Help to understand the code!
Hello, everyone! I'm learning JAVA for applying to a job exam and I'd like to know what is really happening (output) in the code below that was used in a previous exam. Thank you so much for your attention and participation.
[code = Java]
public class Va1 {
public static String getStr() {
return “abcdefghijklmnop“;
}
public String ini(String s, int cpr) {
return s.substring(0, cpr);
}
public String fin(String s, int cpr) {
return ini(s, cpr)+s.substring(s.length()-cpr, s.length());
}
}
public class Va2 extends Va1 {
public static String getStr() {
return “0123456789ABCDEF“;
}
public String ini(String s, int cpr) {
return s.substring(s.length()-cpr, s.length());
}
public static void main(String[] args) {
Va1 o=new Va2();
System.out.println(o.fin(o.getStr(), 5));
}
}
