Compare 2 text files

Question

Hello guys ... I want to compare two text files and then print line if the files are identical or not. What I have here is comparing linie by line and is printing after each line. How can compare all the text and after that just print if all the file is the same or not
import java.io.BufferedReader;
import java.io.FileReader;
public class compare
     public compare() throws Exception
          BufferedReader fx = new BufferedReader(new FileReader("1.txt"),1024);
          BufferedReader sx = new BufferedReader(new FileReader("2.txt"),1024);
String s;
String y;
while ((s=fx.readLine())!=null)
if ((y=sx.readLine()).equals (s))
     System.out.println("These line is the Same");
else
         System.out.println("These line is different");
sx.close();
fx.close();
     public static void main(String[] args) throws Exception
             new compare();
}Thanks

do you have any idee what could be the problem?Yes, all sorts of things.
Don't compare Strings with ==
sx.readLine() == fx.readLine()Use equals() instead
sx.readLine().equals(fx.readLine())Do you know what the word 'different' means?
if (sx.readLine() == fx.readLine())
        different = true;If so, then why do you set 'different' to true when the lines are the same?
if (sx.readLine() != fx.readLine())
     System.out.println("This file is identical");You've already read all the lines in the files, why are you reading again? Use the boolean you set in your loop!
if (different)
    System.out.println("File is different");
