Consider the following code, and suppose the main method in Sub is executed. public class Super { private String y; public Super () { stut();} public void stut() { if (y == null) {y = “cat”;} else {y = y + y;}} } public class Sub extends Super { private String x; public Sub (String s) { x = s;} @Override public void stut() { x = x + x; } public static void main(String[] args) { Super s = new Sub(“dog”); } } Is this true or false: the stut() method in Super is invoked
