Java Exercises: Restore the original string by entering the compressed string with this rule

Java Basic: Exercise-238 with Solution

When character are consecutive in a string , it is possible to shorten the character string by replacing the character with a certain rule. For example, in the case of the character string YYYYY, if it is expressed as # 5 Y, it is compressed by one character.
Write a Java program to restore the original string by entering the compressed string with this rule. However, the # character does not appear in the restored character string.
Note: The original sentences are uppercase letters, lowercase letters, numbers, symbols, less than 100 letters, and consecutive letters are not more than 9 letters.

Input:
Multiple character strings are given. One string is given per line.
Output: The restored character string for each character on one line.

Sample Solution:

Java Code:

import java.util.*;
public class Main 
{
    public static void main(String[] args) 
    {
        Scanner stdIn = new Scanner(System.in);
		    System.out.println("Input the text:");
            String str = stdIn.next();
            for(int i = 0; i < str.length(); ++i)
            {
                if(str.charAt(i) == '#')
                {
                    for(int j = 0; j < (str.charAt(i + 1) - '0'); ++j)
                    {
                        System.out.print(str.charAt(i + 2));
                    }
                    i += 2;
                }
                else
                {
                    System.out.print(str.charAt(i));
                }
            }
            System.out.println();
    }
}

Sample Output:

Input the text:
XY#6Z1#4023
XYZZZZZZ1000023
