Create a class which ask the user to enter a sentence, and it should display count of each vowel type in the sentence. The program should continue till user enters a word “quit”. Display the total count of each vowel for all sentences

CODE:
import java.util.*;
class CountVowel
{
     public static int a,e,i,o,u;
     public static void main(String m[])
    {
           Scanner in=new Scanner(System.in);
           String s=new String();
           while(true)
           {
                  int ta=0,te=0,ti=0,to=0,tu=0;
                  System.out.print("\nEnter A line :");
                  s=in.nextLine();
                  if(s.equals("quit"))
                 {
                        break;
                  }
                  else
                  {
                         int n=s.length()-1;
                        for(int x=0;x<=n;x++)
                       {
                            switch(s.charAt(x))
                           {
                       case 'a' : case 'A' : a++; ta++;
                      break;
                 case 'e' : case 'E' : e++; te++;
                      break;
                 case 'i' : case 'I' : i++;  ti++;
                      break;
                 case 'o' : case 'O' : o++; to++;
                   break;
                 case 'u' : case 'U' : u++; tu++;
                   break;
         }

              }
              System.out.println("\n\n In this statement:");
             System.out.println("a comes: "+ta+" times");
             System.out.println("e comes :"+te+" times");
              System.out.println("i comes :"+ti+" times");
             System.out.println("o comes: "+to+" times");
             System.out.println("u comes :"+tu+" times");
        }
          }
          System.out.println("\n\n Totle numbers of the vovels::");
          System.out.println("a comes "+a+" times");
          System.out.println("e comes "+e+" times");
          System.out.println("i comes "+i+" times");
          System.out.println("o comes "+o+" times");
          System.out.println("u comes "+u+" times");
     }
}
OUTPUT :
