System.out.println("2");
}
System.out.println(test instanceof TP1);//line 1
}
public class Test implements TP{
public static void main(String[] args) {
Test test=new Test();
System.out.println(test instanceof TP1);
}
public interface TP extends TP1 {
}
public interface TP1 {
}
public class Test {
public static void main(String[] args) {
Test test=new Test();
}
void call() throws FileNotFoundException{

How many ways Child class of test Class can override call method?
