Read File to Byte Array 

Apache Commons IO is a java library with simple IO utilities and filters. This requires the library commons-io-2.1.jar to be in classpath. The following example shows using FileUtils.readFileToByteArray() API. It returns the entire file content as byte array.

File Name  :  C:/Test/rule_engine_names.txt

File Name  :  
com/bethecoder/tutorials/commons_io/tests/ReadFileToByteArray.java

package com.bethecoder.tutorials.commons_io.tests;

import java.io.File;
import java.io.IOException;

import org.apache.commons.io.FileUtils;

public class ReadFileToByteArray {

  /**
   @param args
   @throws IOException 
   */
  public static void main(String[] argsthrows IOException {
    File file = new File("C:/Test/rule_engine_names.txt");
    byte [] fileBytes = FileUtils.readFileToByteArray(file);
    String fileContent = new String(fileBytes);
    System.out.println(fileContent);
  }
}
   

It gives the following output,
