//Program to find frequency count of letters in a given text

import java.util.*;
class fcount
     {
   public static void main(String args[])
      {
    char ch;
    String s;
    int i,f=0;
    System.out.println(" Enter a string : ");
    Scanner obj=new Scanner(System.in);
    s=obj.nextLine();
    char a[]=s.toCharArray();
    System.out.println("Enter a character to find its frequency : ");
    ch=obj.next().charAt(0);
    for(i=0;i<a.length;i++)
       {
        if(ch==a[i])
            f++;
       }
    System.out.println("\n Frequency count of "+ch+" is : "+f);
    System.out.println();
     }
}

The Output will be similar to this
