Executing the classes is called a thread. We can read or write the java package using this package. It consists of important sub-packages like java.
A Server is a machine that provides services to other computers in a network. Using java. An applet is dynamically interactive programs Applets are client side programs. There are five data type as follows 1. Integer Data Types: These data types represent numbers without decimal point like 10, , , 0 etc.
Float Data Type: Single Point These data types represent numbers with decimal point like Data Types float Single precision double double precision Ex: Character Data Type: Data Types Char Ex: What is Unicode System? A bit character set standard, designed to include characters appearing in most languages including Chinese, Japanese, etc.
Unicode is a standard to include alphabets from all human languages into java.
Unicode system uses 2 bytes of memory to represents a single character. String Data Type: Boolean Data Type: This data type represents two values, either true or false or binary values like 1 or 0. ASCII -: American Standard Code for Information Interchange A code for information exchange between computers made by different companies; A string of 7 binary digits represents each character; used in most microcomputers.
Operators An operator is a symbol that can perform an operation on operands variable ; Operators are convenient to program or to do convenient to do programming. If an operator acts on a single variable Operand then it is called as Unary operator. If an operator acts on a two variables Operands then it is called as Binary operator. If an operator acts on a three variables Operands then it is called as ternary operator. There are twelve Operators as follows 1. Membership or. Dot Operators Instanceof Operators New Operators Arithmetic Operators: These operators performs basic arithmetic operations etc.
Unary Operators: This operator negates the value of variable. This operator is increases the value of variable by 1.
In Pre Increment. Increment is done first, and then all other operations are done later. In Post Increment. All other operations are done first; and then increment is done at the end.
This operator is decreases the value of variable by 1. In Pre Decrement. Decrement is done first, and then all other operations are done later. In Post Decrement. All other operations are done first; and then Decrement is done at the end. Unary Minus -: This operator is changes the sign value of variable.
Assignment Operators: This operators store a value into a variable. Relational Operators: These operators are supports to compare two quantities; they are used in construction of simple conditions. Logical Operators: These operators are used to construction to compound conditions. Boolean Operators: Bitwise Operators: These operators are used for testing, complementing or shifting bits to the right or left.
A list of seven Bitwise operators as follows 1. Bitwise OR 4. This operator performs ANDing operation on individual bits of numbers. Truth Table: It gives the relations between input bits to output bits. This operator performs ORing operation on individual bits of numbers. Conditional Operators: The conditional operator consist of two symbols?
It acts upon three variables so it is called ternary Operators. Dot Operators: This operator represents the membership. Dot operator can use as follows To refer to class and interfaces of a packages. Class Ex: BufferedReader; To refer to variable of a class. To refer to method of a class. Sqrt is a static method of the Math class.
Instanceof Operators: This operator is useful to know whether an object belongs to a class or an object. New Operators: This operator is useful to create an object to a class or an object. Control Statements The Control statements are changes the flow of the execution of programing statements. Using control statements it is possible to create computers and difficult programs with complex or critical logics. Control statements are divided into 3 parts, they are 1. Branching Statements 2.
Looping Iterative statements 3.
Jump statements Branching Statements: Branching conditional statements can be divided into two parts they are Un Conditional Conditional. Un Conditional: The keywords goto are reserved but not used. In the early days of Java, it is a UnConditional Statement; Java does not allow the goto control statement because a mass of tangled jumps and conditional branches that makes a program virtually impossible to understand.
This conditional statements executes a task one or more statements depending upon whether a conditional is true or not. This conditional statements is useful to execute a particular task from among several tasks depending upon the value of a variable. Statements 1;. Case n: Statements n; [default: If none of the statements are selected in the switch statement then default case will be executed by default.
Switch Statement is most suitable to Menu Driven programs. Looping Iterative statements: A loop iterative can execute several times but a statement can execute in one time there are four types of looping statements. The for loop operates as follows. When the loop first starts, the initialization portion of the loop is executed. Generally, this is an expression that sets the value of the loop control variable, which acts as a counter that controls the loop.
It is important to understand that the initialization expression is only executed once. Next, condition is evaluated. This must be a Boolean expression. It usually tests the loop control variable against a target value. If this expression is true, then body will executed. If it is false, the loop terminates. Next, the iteration portion of the loop is executed. The loop then iterates, first evaluating the conditional expression, then executing the body of the loop, and then executing the iteration expression with each pass.
This process repeats until the controlling expression is false. For loop is used to execute for a fixed no. We can write for loop by eliminating initialization; condition; iteration expressions or any two expressions or all of the three expressions.
A loop that is executed for ever is called infinite looping statement. Infinite loops are draw back in a program To terminate or stop the continuous execution of infinite looping program it is needed to use a shortcut key on keyboard.
Nested Loops Java allows loops to be nested. That is, one loop may be inside another. For example, here is a syntax that nests for loops: This loop repeatedly executes group of statements foreach element of a collection A collection represents a group of elements or objects. Using foreach statement each element of an array arr will executes. A jump statement allows your program to execute in a non-leaner fashion.
Core Java: An Integrated Approach by R. Nageswara Rao
Java supports three jump statements: These statements transfer control to another part of your program. In Java, the break statement has three uses. First, as you have seen, it terminates a statement sequence in a switch statement. Second, it can be used to exit a loop. Third, it can be used as a civilized form of goto. The last two uses are explained here. Using break to exit a loop Ex. Using break as a Form of Goto: The general form of the labeled break statement is shown here: When this form of break executes, control is transferred out of the named block of code.
The labeled block of code must enclose the break statement, but it does not need to be the immediately enclosing block. This means that you can use a labeled break statement to exit from a set of nested blocks. But you cannot use break to transfer control to a block of code that does not enclose the break statement.
This is after second block. It is useful to force an early iteration of a loop. That is, you might want to continue running the loop, but stop processing the remainder of the code in its body for this particular iteration.
Core Java: An Integrated Approach
Here is an example program that uses continue to cause two numbers to be printed on each line: Here is an example program that uses continue to print a triangular multiplication table for 0 through 9. The last control statement is return. The return statement is used to explicitly return from a method. That is, This return statement immediately terminates the method in which it is executed and come back to the calling method.
This return statement can be return some resulting value to the calling method. The following example illustrates this point: Return statement in main method will terminate the application.
What is difference between System. Represents normal termination. Represents termination due to an error. IO Streams basics A Stream represents the act of flow of data from one place to another place. A stream is an abstraction that either produces or consumes information. Play a video or audio file as it downloads from the Internet. There are two types of streams 1.
They are reading or receive the data. They are writing or send the data. All streams are represented as classes in java. The Predefined Streams: All Java programs automatically import the java.
This package defines a class called System, which encapsulates several aspects of the run-time environment. For example, using some of its methods, you can obtain the current time and the settings of various properties associated with the system.
System also contains three predefined stream variables, in, out, and errs. These fields are declared as public and static within System. This means that they can be used by any other part of your program and without reference to a specific System object. By default, this is the console. These are byte streams, even though they typically are used to read and write characters from and to the console.
