corejava-string-handling: Write a program that reads in a String and replace the numerals

Write a program that reads in a String. If a word in the String contains a numeral n (0 < n < 10) then your program must replace that numeral by the character that follows the numeral repeated n times. It can be assumed that there is no numeral at the end of any word.

Sample Input:

I wo3rk a2t Ig5ni6te.

Sample Output:

I worrrk att Ignnnnnitttttte.

import java.util.Scanner;


public class StringFormatter {
public static void main(String[] args) {
Scanner input=new Scanner(System.in);
System.out.println(replaceNumerals(input.nextLine()));
}

public static String replaceNumerals(String input){
StringBuilder output=new StringBuilder();
for(int i=0;i<input.length();i++){
if(Character.isDigit(input.charAt(i))){
for(int j=1;j<Integer.valueOf(Character.toString(input.charAt(i)));j++){
output.append(input.charAt(i+1));
}
}else{
output.append(input.charAt(i));
}
}
return output.toString();
