What's wrong?

Question about the task

StringHelper class

Java Syntax, Level 6, Lesson 8

Resolved

It says it won't compile on the server but it runs fine on my computer?

public class StringHelper {
    public static String multiply(String s) {
        return s.repeat(5);
    }

    public static String multiply(String s, int count) {
        return s.repeat(count);
    }

    public static void main(String[] args) {

    }
}

Make the StringHelper class, which will have 2 static methods:
String multiply(String s, int count) - returns a string that has been repeated count times.
String multiply(String s) - returns a string that has been repeated 5 times.

For example:
Amigo -> AmigoAmigoAmigoAmigoAmigo

Requirements:

The program must not read data from the keyboard.
The StringHelper class's methods must return a string.
The StringHelper class's methods must be static.
The StringHelper class's methods must be public.
The multiply(String s, int count) method must return a string that has been repeated count times.
The multiply(String s) method must return a string that has been repeated 5 times.

package com.codegym.task.task06.task0611; /* StringHelper class */ public class StringHelper { public static String multiply(String s) { return s.repeat(5); } public static String multiply(String s, int count) { return s.repeat(count); } public static void main(String[] args) { } }

b.s. . Please CodeGym be more carefully with the requirements special the output . the task is very simple use of encapsulation but the out put i.e "Amigo ->" " AmigoAmigoAmigoAmigoAmigo " the first fragmento "Amigo ->" looks like is part of the requirements. I could solve it in 1 or 2 attempts. please avoid doubts on yours requirements. thanks . :)

String does not have a repeat method that can be used like this

https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/lang/String.html Yes it does. But I discover it is only in Java 11 so this must be the problem, that the server has an earlier version.

yes you are right, its available in Java 11 which was released in September this year, I guess we have version 10 which does not support it. Here you can use concat method or maybe a loop to add the string to itself 'n' number of times

It won't compile, or it won't validate?

It won't compile on the server but it compiles on my computer. I think I figured out what's going on. I have Java 11, but the server must have an older version in which the repeat method doesn't exist.
