I know, but i want to know

Question about the task

Resolved

I know i have to use the Integer "a" in the loop for. But, why if i use other Integer "b" the loop dont work?

1. Create a list of strings.
2. Add 5 different strings to it.
3. Display its size on the screen.
4. Use a loop to display its contents, each value on a new line.

Note:
Add strings to the list only after the list is initialized.

Requirements:

The program should not read anything from the keyboard.
Declare an ArrayList<String> variable and immediately initialize it.
The program should add any 5 strings to the list.
The program should display the size of the list on the screen.
The program should display the contents of the list, each value on a new line.

package com.codegym.task.task07.task0707; import java.util.ArrayList; /* What sort of list is that? */ public class Solution { public static void main(String[] args) throws Exception { ArrayList <String> list = new ArrayList<String>(); list.add("CASA"); list.add("CAA"); list.add("ASA"); list.add("CAA"); list.add("CA"); int i = list.size(); for (int a = 0; a < i; a++){ int b = 0; String s = list.get(b); System.out.println(s); b++; } //write your code here } }

solution

because every loop cycle will set b to 0. Try moving line 20 to outside the loop if you want your desired result.
