Hi Friend,

Try the following code:

import java.util.*;
class  TotalOccurrences
{
    public static void main(String[] args) 
    {
        int count=0;
        Scanner input=new Scanner(System.in);
        System.out.print("Enter Sentence: ");
        String str=input.nextLine();
        System.out.print("Enter string to search: ");
        String st=input.nextLine();
        StringTokenizer stk=new StringTokenizer(str);
        while(stk.hasMoreTokens()){
            String s=stk.nextToken();
            if(s.equals(st)){
                count++;
            }
        }
        System.out.println(st+" occurs "+count+" times in a sentence");
        }
}

Thanks
