Why does the following code not compile? Java C# public class XYZ { private int myNum; public XYZ() { myNum=0; public class XYZ { private int myNum: public XYZ() { myNum=0; public XYZ(int n1) { myNum-n1: public XYZ (int n1) { myNum = n1; public class ABC extends XYZ { private int num2; public ABC() { public class ABC: XYZ { private int num2; public ABC() { myNum=0; } myNum=0; num2=0; pubilc ABC(int n1) { myNum=n1; num2=n1*2; num2=0; I public ABC (int n1) { myNum = n1; num2 =n1*2; class Main { public static void main(String[] args) { ABC myABC = new class MainClass{ public static void Main (string[] args) { ABC myABC= new ABC(); ABC(): } }
