Java String Occurrence in a String

     

In this program you will learn how to find the occurrence of a String in another String. Here we have already taken a String.

Description of the code:

In the program code given below, we will find another String from a String which already exists. Here we have taken two variables- result and len. We have applied a condition here that if length is greater than zero then it will start searching for the string with the help of the method base.indexOf();. And once it will find the string at the given position then it will display the following output. 

The code of the program is given below:

import java.util.*;
import java.io.*;
import java.lang.String;

public class StringCount{
  public static void main(String args[]){
  String searchFor = "is";
  String base = "This is the method";
  int len = searchFor.length();
  int result = 0;
  if (len > 0) {  
  int start = base.indexOf(searchFor);
  while (start != -1) {
  result++;
  start = base.indexOf(searchFor, start+len);
  }
  }
  System.out.println(result);
  }

Output of the program:

C:\unique>javac StringCount.java

C:\unique>java StringCount
2

C:\unique>

to search without using string function

this program is very nice. but if u write without using any function then any one can easily understand.
