11. Types of Operator part1

 

1.  Arithmetic Operators

These are used to perform basic mathematical operations.

• Addition (+): Adds two numbers.

  int a = 5;
  int b = 3;
  int sum = a + b; // sum is 8
  

• Subtraction (-): Subtracts one number from another.

  int difference = a - b; // difference is 2

• Multiplication (*): Multiplies two numbers.

  int product = a * b; // product is 15

• Division (/): Divides one number by another.

  int quotient = a / b; // quotient is 1

• Modulus (%): Gives the remainder of a division.

  int remainder = a % b; // remainder is 2

2.   Relational Operators

These are used to compare two values.

• Equal to (==): Checks if two values are equal.

  boolean isEqual = (a == b); // isEqual is false
  

• Not equal to (!=): Checks if two values are not equal.

  boolean isNotEqual = (a != b); // isNotEqual is true
  

• Greater than (>): Checks if one value is greater than another.

  boolean isGreater = (a > b); // isGreater is true
  

• Less than (<): Checks if one value is less than another.

  boolean isLess = (a < b); // isLess is false
  

• Greater than or equal to (>=): Checks if one value is greater than or equal to another.

  boolean isGreaterOrEqual = (a >= b); // isGreaterOrEqual is true
  

• Less than or equal to (<=): Checks if one value is less than or equal to another.

  boolean isLessOrEqual = (a <= b); // isLessOrEqual is false.

3.   Logical Operators

      These are used to combine multiple boolean expressions.

• AND (&&): Returns true if both conditions are true.

  boolean result = (a > 2 && b < 5); // result is true
  

• OR (||): Returns true if at least one condition is true.

  boolean result = (a > 5 || b < 5); // result is true
  

• **NOT (!) **: Reverses the logical state.

  boolean result = !(a > b); // result is false

4. Bitwise Operators

These operate on binary representations of integers.

• AND (&): Performs a bitwise AND.

  int result = a & b; // result is 1 (binary 0101 & 0011 = 0001)

• OR (|): Performs a bitwise OR.

  int result = a | b; // result is 7 (binary 0101 | 0011 = 0111)
  

• XOR (^): Performs a bitwise exclusive OR.

  int result = a ^ b; // result is 6 (binary 0101 ^ 0011 = 0110)
  

• NOT (~): Performs a bitwise NOT.

  int result = ~a; // result is -6 (binary 0101 = 1010)
  

• Left Shift (<<): Shifts bits to the left.

  int result = a << 1; // result is 10 (binary 0101 << 1 = 1010)
  

• Right Shift (>>): Shifts bits to the right.

  int result = a >> 1; // result is 2 (binary 0101 >> 1 = 0010)

5. Assignment Operators

These are used to assign values to variables.

• Simple assignment (=): Assigns the right-side value to the left-side variable.

  int c = a; // c is 5
