Hi Friend,

Try the following code:

import java.util.*;

public class CountCharacters {
public static void main(String[] args) {
System.out.println("Enter string");
Scanner input=new Scanner(System.in);
String str=input.nextLine();
String newString=str.replace(" ","");
String s = str.replaceAll((String.format("(.)(?<=(?:(?=\\1).).{0,%d}(?:(?=\\1).))", str.length())), "");
String st=s.replace(" ","");
char character[]=st.toCharArray();
char ch=' ';
System.out.println( "character : Occurence");
for(int i=0;i<character.length;i++){
ch=character[i];

System.out.println( ch+ " " + count(ch,newString));
}
}
static int count(char c, String str) {
if (str == null) return 0;
int cnt = 0;
for (int i = 0;; cnt++) {
if ((i = str.indexOf(c,i)+1) == 0) break;
}
return cnt;
}
}

Thanks
