Operators in Java

Hey there! In this guide, we'll explore operators in Java. Operators are symbols that instruct the compiler to perform specific operations on variables or values. Java supports a variety of operators, including arithmetic, relational, logical, bitwise, and more. Let's dive in!

1. Arithmetic Operators​

Arithmetic operators perform mathematical operations such as addition, subtraction, multiplication, and division.

Example:​

int x = 10, y = 5;
System.out.println(x + y);  // Output: 15
System.out.println(x - y);  // Output: 5
System.out.println(x * y);  // Output: 50
System.out.println(x / y);  // Output: 2
System.out.println(x % y);  // Output: 0

2. Relational Operators​

Relational operators compare two values and return a boolean result (true or false).

Example:​

int x = 10, y = 5; System.out.println(x == y);  // Output: false
System.out.println(x != y);  // Output: true
System.out.println(x > y);   // Output: true
System.out.println(x < y);   // Output: false
System.out.println(x >= y);  // Output: true
System.out.println(x <= y);  // Output: false

3. Logical Operators​

Logical operators are used to perform logical operations and combine multiple conditions.

Example:​

int x = 10, y = 5; System.out.println(x > 5 && y < 10);  // Output: true
System.out.println(x > 5 || y > 10);  // Output: true
System.out.println(!(x > 5));  // Output: false

4. Assignment Operators​

Assignment operators are used to assign values to variables.

Example:​

int x = 10, y = 5; x += y;  // Equivalent to x = x + y
System.out.println(x);  // Output: 15

5. Increment and Decrement Operators​

Increment and decrement operators are used to increase or decrease a variable's value by 1.

Example:​

int x = 10; System.out.println(++x);  // Output: 11 (Pre-increment)
System.out.println(x--);  // Output: 11 (Post-decrement)
System.out.println(x);    // Output: 10

6. Bitwise Operators​

Bitwise operators operate on bits and perform bit-level operations.

Example:​

int x = 10, y = 5; System.out.println(x & y);   // Output: 0
System.out.println(x | y);   // Output: 15

7. Ternary Operator​

The ternary operator is a shorthand for an if-else statement.

Example:​

int x = 10; int result = (x > 5) ? 100 : 200;
System.out.println(result);  // Output: 100
