Write a program in Java to find out the number of occurrences of the string "mobnet" from a file (c:\test.txt)?

import java.io.BufferedReader;

import java.io.FileReader;

import java.util.regex.Matcher;

import java.util.regex.Pattern;

public class TxtCount {

/**

* @param args

* /

public static void main(String[] args) throws Exception {

BufferedReader br = new BufferedReader(new FileReader("C:\\test.txt"));< /p>

StringBuilder sb = new StringBuilder();

while (true) {

String str = br.readLine();

if (str == null)

break;

sb.append(str);

}

Pattern p = Pattern.compile ("mobnet");

Matcher m = p.matcher(sb);

int count = 0;

while(m.find()) {

count++;

}

System.out.println("mobnet-*** appeared" + count + "times");

p>

}

}
