Method Overriding

1. Program

//Find what it gives Compiletion Error / Compiletion Successfully / Output ? 
class M
{ 
 void test()
 {
  System.out.println("From M");
 }
}

class N extends M
{ 
 protected void test()
 {
  System.out.println("From N");
 }
 public static void main(String[] args)
 {
  N n1 = new N();
  n1.test();
  System.out.println("Done");
 }
}

2. Program

//Find what it gives Compiletion Error / Compiletion Successfully / Output ? 
class T
{
 static void test()
 {
  
 }
}

class U extends T
{
 void test() // must be static for Overriding
 {
  
 }
}
