Given integer variables x and y, print their values and and their sum. For example if x is 1 and y is 2 , print: The sum of 1 and 2 is 3 There are 4 codes but only 1 is correct. Here is one possible correct solution to the above: System.out.println("The sum of " +x+ " and " +y+ "is " +(x+y) ); Here are 3 other codes with errors: System.out.println("The sum of " +x+ " and " +y+" is " +x+y ); System.out.println ("The sum of x and +y is " +x+y ); System.out.println("The sum of x and y is x+y "); Write the test cases to distinguish the above correct code from the above incorrect codes
