The ApacheSW Commons IOS library has a very useful tool for allowing you to get a List of the lines of a File, the readLines() method of the FileUtils class. The ReadListOfLinesFromFile class demonstrates this.

ReadListOfLinesFromFile.java

package test;

import java.io.File;
import java.io.IOException;
import java.util.List;

import org.apache.commons.io.FileUtils;

public class ReadListOfLinesFromFile {

	public static void main(String[] args) {
		try {
			File file = new File("test.txt");
			List<String> lines = FileUtils.readLines(file);

			for (String line : lines) {
				System.out.println("line:" + line);
			}

		} catch (IOException e) {
			e.printStackTrace();
		}
	}
}

The test.txt file is shown here:

test.txt

this is
a test
of commons io

Executing ReadListOfLinesFromFile with test.txt generates the following console output:

line:this is
line:a test
line:of commons io
