Java Operators

         Java supports rich set of operators. we have already used several of them such as = , +, -, and * . an operator is a symbol that tells a computer to perform certain mathematical or logical manipulations. Operators are used in programs to manipulate data and variables. Java operators can be classified into

 1.  Arithmetic operators 

2. Relational Operators 

3. Logical Operators 

4. Assignment Operators 

5. Increment and Decrement operators 

6. Conditional Operators 

7. Bitwise operators 

8. Special operators. 

1.  Arithmetic operators 

        Arithmetic operators are used in mathematical expressions in the same way that they are used in algebra. Java provides all the basic arithmetic operations.The following table lists the arithmetic operators:

  • Addition (+)
  • Subtraction (-)
  • Multiplication (*)
  • Division (/)
  • Modulus (%)

 program : 01


output:01


2. Relational Operators

  • Equal to (= =)
  • Not equal to (!=)
  • Greater than (>)
  • Less than (<)
  • Greater than or equal to (>=)
  • Less than or equal to (<=)

program : 02


 

output:02


3. Logical Operators 

        Java has three logical operators. The logical operators && and || are used when we want to form compound condition by combining two or more relations. An example is: a>b && x==10 An expression of this kind which combines two or more relational expressions is termed as logical expression or a compound relational expression. A logical expression also yields a value of true or false according to the truth table.

  • Logical AND ( && )
  • Logical OR ( || )
  • Logical NOT ( ! )

Truth table 

Op-1         Op-2         Op1&&op-2         Op-1||op2 

True          True             True                     true 

True          False            False                    true 

False         True             False                    true 

False         False            False                   false

program : 03

output:03

4. Assignment Operators

  •  Assignment (=)
  •  Compound Assignment Operators (e.g., +=, -=, *=, /=, %=)

 program : 04


output:04

5. Increment and Decrement operators

  •  Increment (++)
  •  Decrement (--)

program : 05

output:05

6. Conditional Operators

  •  (condition) ? expression1 : expression2

program : 06

output:06


7. Bitwise operators

  • Bitwise AND (&)
  • Bitwise OR (|)
  • Bitwise XOR (^)
  • Bitwise NOT (~)
  • Left Shift (<<)
  • Right Shift (>>)
  • Unsigned Right Shift (>>>)

program : 07

output:07

8. Special operators.

        Java supports some special operators of interest such as instance of operator and member selection operator(.)

Java unit-1 history , C++ vs Java , java environment

Java History   Java is one of the most influential programming languages, widely used in various applications, from web development to mobile applications and large-scale enterprise systems. Here's a brief overview of its history: 1. Origins and Development: 1991: Java's development began at Sun Microsystems as part of the Green Project, led by James Gosling, Mike Sheridan, and Patrick Naughton. The project aimed to create a language for programming digital devices like set-top boxes and televisions. 1995:Originally called Oak (after an oak tree outside Gosling's office), the language was later renamed Java, inspired by Java coffee. It was officially released by Sun Microsystems as Java 1.0. The language was designed to have the "Write Once, Run Anywhere" (WORA) capability, allowing code to run on any device that supports the Java Virtual Machine (JVM). 2. Key Features: Java's popularity grew due to several features: Platform Independence: Java applications a...

java program structure                     Java program may contain many classes of which only one class define a main method. Class contain data members and methods that operate on the data members of the class.   Documentation Section In Java, comments are used to annotate code and are ignored by the compiler. Java supports two types of comments: single-line and multi-line comments. 1.Single-Line Comments Syntax: Single-line comments start with `//` and continue to the end of the line. Use Case: Ideal for brief explanations or notes that occupy only one line. Example: class MyClass {      public static void main(String[] args)            {              int number = 10; // This is a single-line comment              System.out.println(number); // Outpu...
