Using BufferedReader.readLine() in a while loop properly

Question

So I\'m having an issue reading a text file into my program. Here is the code:

     try{
        InputStream fis=new FileInputStream(targetsFile);
        Bu         


        

Answer 1

Concept Solution:br.read() returns particular character's int value so loop continue's until we won't get -1 as int value and Hence up to there it prints br.readLine() which returns a line into String form.

    //Way 1:
    while(br.read()!=-1)
    {
      //continues loop until we won't get int value as a -1
      System.out.println(br.readLine());
    }

    //Way 2:
    while((line=br.readLine())!=null)
    {
      System.out.println(line);
    }

    //Way 3:
    for(String line=br.readLine();line!=null;line=br.readLine())
    {
      System.out.println(line);
    }

Way 4: It's an advance way to read file using collection and arrays concept How we iterate using for each loop. check it here http://www.java67.com/2016/01/how-to-use-foreach-method-in-java-8-examples.html
