What will happen when you attempt to compile and run the following code?
abstract class Hall{
public abstract void getFireStation();
}

public class Haddon extends Hall{

public static void main(String argv[]){
new Haddon().getFireStation();

}

ds Question is from Marcus Green according to me the ans have to be option 3
plz help me to trace the flow
public synchronized void getFireStation(){
System.out.print("opposite");
}

}



1) Compile time error, synchronized can only be used in a class that extends Thread
2) Compile time error, malformed method getFireStation in class Hall.
3) Compilation and output of opposite at runtime
4) Compile time error, code within main method is incorrect

Yes the code prints "opposite" because of this method
