import java.util.Scanner; public class Calc5{ public static void main(String args[]){ Scanner obj = new Scanner(System.in); System.out.println("please enter operand1, operand2 and operator(+,-,x,/)"); int a = obj.nextInt(); int b = obj.nextInt(); double c ; char op = obj.nextChr ();

                if(op == '+'); 
                c = a+b;
                    System.out.println ("a" +"+"+ "b");
                    System.out.println("the result is=" + c);

                if (op == '-');
                c = a-b;
                    System.out.println ("operand1" +"-"+ "operand2");
                    System.out.println("the result is=" + c);

                 if  (op == '/') ;
                c= a/b;
                       System.out.println ("operand1" +"/"+ "operand2");
                       System.out.println("the result is=" + c);

                if (op == '*'); 
                c = a * b;
                    System.out.println ("operand1" +"x"+ "operand2");
                    System.out.println ("the result is=" +c);

} // end of main

} // end of class
