How this code is giving int output

Question

import java.util.Scanner;
public class Program
{
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
String n =sc.nextLine();
int a =n.length();
String w="";
char [] x = {'G','

Answer 1

Once check the line w=w+j
You are adding integer(index)
Suppose n=$arada, index of $ is 0
So, w=w+0 (since, $==$)... At this time the value of j is 0...so,w=w+0 = 0(which is in string format) and you are getting the result as 0 (which you are thinking the result is in integer format). If you want a string, then try with arrays... Hope you understand... 👍
