Java如何读取一个文本文件的内容呢？

实现思路:
     1.定义一个BufferedReader StringBuilder
	 2.借助while循环，即可依次将文本文件读出来

package com.java265.other;

import java.io.BufferedReader;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileReader;
import java.io.IOException;
import java.io.InputStream;
 
public class Test {
	/*
	 * java265.com 读取文本文件内容的方法分享
	 *  
	 **/
	public static void main(String[] args)   {
      String filePath = "E://person/java265.com/java.txt";
      System.out.println(readFileContent(filePath));
      }
	
	public static String readFileContent(String fileName) {
	    File file = new File(fileName);
	    BufferedReader reader = null;
	    StringBuffer sbf = new StringBuffer();
	    try {
	        reader = new BufferedReader(new FileReader(file));
	        String tempStr;
	        while ((tempStr = reader.readLine()) != null) {
	            sbf.append(tempStr);
	        }
	        reader.close();
	        return sbf.toString();
	    } catch (IOException e) {
	        e.printStackTrace();
	    } finally {
	        if (reader != null) {
	            try {
	                reader.close();
	            } catch (IOException e1) {
	                e1.printStackTrace();
	            }
	        }
	    }
	    return sbf.toString();
	}
}
