Bitwise	bitwise AND	&
	bitwise exclusive OR	^
	bitwise inclusive OR	|
Logical	logical AND	&&
	logical OR	||
Ternary	ternary	? :
Assignment	assignment	= += -= *= /= %= &= ^= |= <<= >>= >>>=

Increment/Decrement Operator

class Demo(){
    public static void main(){
        int x = 10;
        System.out.println(x++);
        System.out.println(++x);
    }
    /* Output:
    10
    12
    */
}

Arithmetic Operators

Arithmetic Operators are:

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

class Arithmetic{
    public static void main(){
        int a = 10;
        int b = 5;
        System.out.println(a+b);
        System.out.println(a-b);
        System.out.println(a*b);
        System.out.println(a/b);
        System.out.println(a%b);
    }
    /* Output:
    15
    5
    50
    2
    0
    */
}

Relational Operator

Relational operators are <, >, <=, >=, !=, instanceOf()

class Relational{
    public static void main(String [] args){
        int a, b, c;
        a = 10;
        b = 20;
        c = 25; 
        System.out.println(a > b);  // false
        System.out.println(a < b);  // true
        System.out.println(a = b);  // 20
        System.out.println(a != b);  // false
        System.out.println(a <= b);  // true
        System.out.println(a >= b);  // true
    }
}

Logical Operators

class Logical{
    public static void main(String [] args){
    // && operator
    System.out.println((5 > 3) && (8 > 5));  // true
    System.out.println((5 > 3) && (8 < 5));  // false

    // || operator
    System.out.println((5 < 3) || (8 > 5));  // true
    System.out.println((5 > 3) || (8 < 5));  // true
    System.out.println((5 < 3) || (8 < 5));  // false

    // ! operator
    System.out.println(!(5 == 3));  // true
    System.out.println(!(5 > 3));  // false
    }
}
