package com.bethecoder.tutorials.guava.io_tests;

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

import com.google.common.base.Charsets;
import com.google.common.io.Files;

public class ReadFirstLineOfFileTest {

  /**
   @param args
   @throws IOException 
   */
  public static void main(String[] argsthrows IOException {
    File file = new File("C:\\abcd.txt");
    String firstLine = Files.readFirstLine(file, Charsets.UTF_8);
    System.out.println("First Line : " + firstLine);
