why last two requirement pass?

Question about the task

Resolved

package com.codegym.task.task06.task0611; /* StringHelper class */ public class StringHelper { public static String multiply(String s) { String result =""; //write your code here for (int i = 0; i < 5; i++) { result = s; // System.out.println(result); } return result; } public static String multiply(String s, int count) { String result =""; //write your code here for (int i = 0; i < count; i++) { result = s; // System.out.println(result); } return result; } 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.

solution

This program works this way: Line 9 "multiply(String s)" method get a String, for example this: "abc", and it is named here variable "s". Inside the loop, in line 13: This command run five times: in the first circle: The value of the variable "result" is set to "abc" in the second circle: The value of the variable is set to "abc" again. in the third circle: The value of the variable is set to "abc" again in the fourth circle: The value of the variable is set to "abc" again in the fifth circle: The value of the variable is set to "abc" again After this, the method return the result: "abc". This is the totally same string-value we passed to the method. The multiplying is not done. Hint: You should be do something to increase the value of the "result" variable in each circle.
