Question

please use java

Write a program that prompts the user to enter line of text (including whitespace). The program then replaces the following vocals with numbers: a = 1, e = 2, i = 3, o = 4, u = 5 and outputs the result to the console. The program does not consider case, so a = 1, A = 1, e = 2, E = 2, etc.

Example:
Input: Hello, how are you?
Output: H2ll4, h4w 1r2 y45?

The program must be error-free to get the points.

import java.util.Scanner;

public class sh {
public static void main(String[] args) {
  
Scanner in=new Scanner(System.in);
System.out.println("Enter sentence: ");
String sentence=in.nextLine();
char[] ch = new char[sentence.length()];
  
// Copy character by character into array
for (int i = 0; i < sentence.length(); i++) {
ch[i] = sentence.charAt(i);
}
for (int i = 0; i < sentence.length(); i++) {
if(ch[i]=='a' ||ch[i]=='A')
ch[i]='1';
if(ch[i]=='e' ||ch[i]=='E')
ch[i]='2';
if(ch[i]=='i' ||ch[i]=='I')
ch[i]='3';
if(ch[i]=='o' ||ch[i]=='O')
ch[i]='4';
if(ch[i]=='u' ||ch[i]=='U')
ch[i]='5';
}
String new_str = new String(ch);
System.out.println(new_str);
  
}
