There are different ways to achieve this -

First One -

try {

File f = new File("data.txt");

FileInputStream fis = new FileInputStream(f);

byte[] content = new byte[fis.available()];

fis.read(content);

String data = new String(content);

String[] split = data.split(System.getProperty("line.separator"));

String lastLine = "";

if(split.length > 0){

lastLine = split[split.length -1];

}

System.out.println(lastLine);

} catch (Exception e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

Second One -

You may try the RandomAccessFile in java.io

First goto the last position

RandomAccessFile rfile = new RandomAccessFile(file,"r");

rfile.seek(file.length());

Third One -

FileInputStream fis=new FileInputStream("D:\\ test\\sample.txt");

String fileContent = new Scanner(fis).useDelimiter("\\Z").next();
