Reading and displaying data from a .txt file

Question

How do you read and display data from .txt files?

Answer 1

You most likely will want to use the FileInputStream class:

int character;
StringBuffer buffer = new StringBuffer("");
FileInputStream inputStream = new FileInputStream(new File("/home/jessy/file.txt"));

while( (character = inputStream.read()) != -1)
        buffer.append((char) character);

inputStream.close();
System.out.println(buffer);

You will also want to catch some of the exceptions thrown by the read() method and FileInputStream constructor, but those are implementation details specific to your project.
