Java Operators

1. Arithmetic Operators:

// Addition
int sum = 5 + 3;  // Result: 8

// Subtraction
int difference = 7 - 4;  // Result: 3

// Multiplication
int product = 2 * 6;  // Result: 12

// Division
int quotient = 10 / 2;  // Result: 5

// Modulus
int remainder = 15 % 4;  // Result: 3

2. Relational Operators:

// Equal to
boolean isEqual = (5 == 5);  // Result: true

// Not equal to
boolean isNotEqual = (4 != 3);  // Result: true

// Greater than
boolean isGreater = (7 > 5);  // Result: true

// Less than
boolean isLess = (2 < 4);  // Result: true

// Greater than or equal to
boolean isGreaterOrEqual = (10 >= 8);  // Result: true

// Less than or equal to
boolean isLessOrEqual = (6 <= 9);  // Result: true

3. Logical Operators:

// Logical AND
boolean resultAnd = condition1 && condition2;  // Result: false

// Logical OR
boolean resultOr = condition1 || condition2;   // Result: true

// Logical NOT
boolean resultNot = !condition1;                // Result: false

4. Assignment Operators:

// Assignment
int x = 10;

// Compound Assignment
int a = 5;
a += 3;  // Equivalent to: a = a + 3;

5. Bitwise Operators:

Bitwise operators perform operations at the bit level.

// Bitwise AND (&)
// Bitwise OR (|)
// Bitwise XOR (^)
// Bitwise NOT (~)
// Left Shift (<<)
// Right Shift (>>)
// Zero-fill Right Shift (>>>)

6. Other Operators:

// Conditional (Ternary) Operator (? :)
int max = (a > b) ? a : b;

// Instanceof Operator
if (obj instanceof MyClass) {
    // code
}

These are some of the main categories of operators in Java. Understanding how to use operators is essential for writing effective and expressive Java code.
