Operators in Java

Basic operators in Java are fundamental building blocks for performing operations on variables and values. Here's an overview of the basic operators in Java:

1. Arithmetic Operators:
   • Addition (+): Adds two operands.
   • Subtraction (-): Subtracts the second operand from the first.
   • Multiplication (*): Multiplies two operands.
   • Division (/): Divides the first operand by the second.
   • Modulus (%): Returns the remainder of the division operation.
2. Assignment Operators:
   • Assignment (=): Assigns the value on the right to the variable on the left.
   • Compound Assignment (+=, -=, *=, /=, %=): Combines arithmetic operation with assignment.
3. Increment/Decrement Operators:
   • Increment (++): Increases the value of a variable by 1.
   • Decrement (--): Decreases the value of a variable by 1.
4. Comparison Operators:
   • Equal to (==): Compares two values for equality.
   • Not equal to (!=): Compares two values for inequality.
   • Greater than (>): Checks if the first operand is greater than the second.
   • Less than (<): Checks if the first operand is less than the second.
   • Greater than or equal to (>=): Checks if the first operand is greater than or equal to the second.
   • Less than or equal to (<=): Checks if the first operand is less than or equal to the second.
5. Logical Operators:
   • Logical AND (&&): Returns true if both operands are true.
   • Logical OR (||): Returns true if at least one of the operands is true.
   • Logical NOT (!): Returns the opposite boolean value of the operand.
6. Bitwise Operators:
   • Bitwise AND (&): Performs a bitwise AND operation.
   • Bitwise OR (|): Performs a bitwise OR operation.
   • Bitwise XOR (^): Performs a bitwise XOR (exclusive OR) operation.
   • Bitwise Complement (~): Flips the bits of its operand.
   • Left Shift (<<): Shifts the bits of the first operand to the left by the number of positions specified by the second operand.
   • Right Shift (>>): Shifts the bits of the first operand to the right by the number of positions specified by the second operand.
   • Unsigned Right Shift (>>>): Shifts the bits of the first operand to the right by the number of positions specified by the second operand, filling in the leftmost bits with zeros.

These operators are used extensively in Java for various operations like mathematical calculations, logical evaluations, bitwise manipulations, and more.
