You have to change the location of file only.
Please rate.

import java.io.File;
import java.io.IOException;
import java.util.Scanner;
public class Hello {
public static void main(String[] args)throws IOException
{
File inputFile = new File("C:/AmitKumar/Eclipse_Workspace/Demo/src/hello.txt");
Scanner scan = new Scanner ( inputFile );
String input=scan.nextLine();
String[] words = input.split("\s+");
int count=0;
input=input.replace('a','$');
input=input.replace('e','$');
input=input.replace('i','$');
input=input.replace('o','$');
input=input.replace('u','$');
System.out.println( input );
for(int i=0;i<words.length;i++)
{
String temp=words[i].toLowerCase();
if(temp.charAt(0)=='t'&& temp.charAt(1)=='h')
{
count++;
}
}
System.out.println("Number of word start with th is : "+count);
}
}
