whats wrong in this code??

Question about the task

StringHelper class

Java Syntax, Level 6, Lesson 8

Under discussion

What changes should I make

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) { String result = "jh"; //write your code here for(int i = 0;i<5;i++){ System.out.print(result); } return result; } public static String multiply(String s, int count) { String result = "jk"; //write your code here for(int i = 0;i<count;i++){ System.out.print(result); } return result; } public static void main(String[] args) { } }

Its confusing the Amigo bit throws you, remove the jk and jh they are not needed. change the System.out for 'result += s' . Nothing else is needed. This is code from a bigger piece, all you need to do is show how to concatinate.

the task requires not to use output method, but only returning the calculation i.e. the method must only calculate, e.g. result = result + s;

You are supposed to call the multiply method on main twice. The first one with a string and an integer and the second one with just a string.

The problem with your implementation is that you should not provide a "result" string in the multiply method. You should use the string that is passed on the method.

Here are some corrections:


package com.codegym.task.task06.task0611;

public class StringHelper {
    public static String multiply(String s) {
        String result = ""; //--> declare it as empty string
        //write your code here
        for(int i = 0;i<5;i++){
        //    System.out.print(result); //----> You are not supposed to print the "result" in the method
              result += s ;     // ----> You are supposed to multiply (add) the string "s" that was passed on the method 5 times
        }
        return result; // --> Return multiplied string

        }

    public static String multiply(String s, int count) {
        String result = ""; //--> declare it as empty string
        //write your code here
        for(int i = 0;i<count;i++){
           //    System.out.print(result); // ----> You are not supposed to print the "result" in the method
              result += s ;     // ----> You are supposed to multiply (add) the string "s" that was passed on the method "count"  times
        }
        return result; // --> Return multiplied string
    }

    public static void main(String[] args) {
            System.out.println(multiply("test")); //----> Test multiply(String s){} method
            System.out.println(multiply("test", 3));// ----> Test multiply(String s, int count){} method


    }
}
