Java Certification Question 0086

What will happen when you attempt to compile and run the following code

public class MySwitch{

public static void main(String argv[]){
MySwitch ms= new MySwitch();
ms.amethod();
}

public void amethod(){
int k=10;
switch(k){
default: //Put the default at the bottom, not here
System.out.println("This is the default output");
break;
case 10:
System.out.println("ten");
case 20:
System.out.println("twenty");
break;
}
}
}

1) None of these options
2) Compile time error target of switch must be an integral type
3) Compile and run with output "This is the default output"
4) Compile and run with output of the single line "ten"

Answer)

1) None of these options

Because of the lack of a break statement after the break 10; statement the actual output will be

"ten" followed by "twenty"
