Java program to find the frequency of word present in string by using String Tokenizer

Write a Java program to find the frequency of word present in string by using  String Tokenizer Class.

Note . The word should not be a substring of a taken of the input string.

Sample Input:

The salesman is carrying a green bottle in the green bag and wearing a green cap. 

The frequency of the word to determine : green

sample output:

The frequency of the word green is : 3

Solution:

Enter any String: 

The salesman is carrying a green bottle in the green bag and wearing a green cap

The frequency of the word to determine: 

green

The frequency of the word The salesman is carrying a green bottle in the green bag and wearing a green cap is :3

import java.util.*;
class FindFrequency
{
   
    public static void main(String arr[])
    {
        Scanner sc=new Scanner(System.in);
        System.out.println("Enter any String: ");
        String s=sc.nextLine();
        System.out.println("The frequency of the word to determine: ");
        String f=sc.nextLine();
        int count=0;
        StringTokenizer st=new StringTokenizer(s);
        String t="";
        while(st.hasMoreTokens())
        {
            t=st.nextToken();
            if(t.equals(f))
            {
                count++;
            }
        }       
        System.out.println("The frequency of the word "+s+" is :"+count);        
    }
}
