Please UseCodeTags for the source code posted.

Also you need to loop through the entire contents of the file and print them. In your code- You are just getting the first line- readLine()- would read one line. But your file contains 2 lines.

For reading the file line by line ,you have to use BufferedReader.readLine() method which returns next line text ,if it end of the file (Stream) it returns null
Following is the code for reading data from file

The File#length() method doesn't tell you how many lines you have in your file.
