Logical operators. &&, | | , !.

Conditional operators ?:

 public class ArithmeticOperators
 {

    public ArithmeticOperators()
         {
        int x = 20 y = 10, z ;
         z=x+y;
        System.out.println("+ operator resulted in " +z);
                public static void main(String arg[])
               
              {
                new Arithmeticoperators();
                 }
                    }
