Hi!
I need help please about Template Pattern in OOP_java.
My task is !
use the Template method pattern to define an abstract class Filter with a public method filter (the template method) that calls the method accept (the hook method) that can be implemented in different ways in the different concrete classes.
Write a test program by extending the class Filter and defining accept so that only strings of at most three characters are accepted.
Thanks to you!
CODE
abstract class Filter<T> {
public void filter(T obj) {
accept(obj);
}
public abstract boolean accept(T obj);
}
class Test extends Filter<String> {
@Override
public boolean accept(String str) {
if (str.length() <= 3) {
return true;
}
return false;
}
}
