Compound Operators

  • +=, -=, *= and /=
  • Makes code compact
  • Operator precedence for compound assignments : The expression on the right side of the = will always be evaluated first!
int x = 2;

x *= 3 + 5;

//This is equivalent to x = x * (3 + 5) and NOT x = (x*2) + 5.

Relational Operators

  • Can be applied to ANY combination of integers, floats or chars.
  • int's can be compared to doubles
  • char's can be compared to int's
                int i = 4;
		double pi = 3.14;
		
		if( i > pi) {
			System.out.println("Greater than pi");
		}
		
		char c = 'C';
		
		if( c > 66) {
			System.out.println("C > B");
		}


Equality Operators

  • '==' and '!=' are used to test for equality.
  • Can't compare inequal types.
