? and : operator in java code example

Example 1: Operators in java

// java assignment operator with examples
public class AssignmentOperatorDemo
{
   public static void main(String[] args)
   {
      int numOne = 60;
      int numTwo = 30;
      numTwo += numOne;
      System.out.println("(+=) : " + numTwo);
      numTwo -= numOne;
      System.out.println("(-=) : " + numTwo);
      numTwo *= numOne;
      System.out.println("(*=) : " + numTwo);
      numTwo /= numOne;
      System.out.println("(/=) : " + numTwo);
      numTwo %= numOne;
      System.out.println("(%=) : " + numTwo);
   }
}

Example 2: Operators in java

// java unary increment (++) operator
public class JavaUnaryOperator
{
   public static void main(String[] args)
   {
      int a = 23;
      // 23 gets printed and increment to 24
      System.out.println("Java post-increment = " + a++);
      // a value was 24, incremented to 25
      System.out.println("Java pre-increment = " + ++a);
   }
}
