Object Oriented Programming (OOPs) - Question 2

Place the Output Options in the Actual Output Sequence to indicate the output from this code:

 class Alpha { 
  public void foo( String... args ) 
   {System.out.print ("Alpha : foo"); } 
  public void bar( String a ) 
   {System.out.print ("Alpha : bar"); } 
} 
public class Beta extends Alpha { 
  public void foo ( String a) 
   {System.out.print ( "Beta : foo" ); } 
  public void bar( String a) 
   {System.out.print( "Beta : bar" ); } 
  public static void main ( String[] argv) { 
   Alpha a = new Beta(); 
   Beta b = (Beta)a; 
   a.foo( "test" ); b.foo( "test" ); 
   a.bar( "test" ); b.bar( "test" ); 
  } 
}
