基本操作--File--获取一个文件的内容

[java]代码库

//获取一个文件的内容
package extractors;

import java.io.*;

public class FileText
{
	//读取一个文件的所有内容
	public static String getText(File f)
	{
		StringBuffer sb=new StringBuffer("");
		try
		{
			FileReader fr=new FileReader(f);
			BufferedReader br=new BufferedReader(fr);
			
			String s=br.readLine();
			
			while(s!=null)
			{
				sb.append(s);
				s=br.readLine();
			}
			br.close();
		}
		catch(Exception e)
		{
			sb.append("");
		}
		
		return sb.toString();
	}

	//读取一个文件的所有内容--重载
	public static String getText(String s)
	{
		String t = "";
		try
		{
			File f = new File(s);
			t = getText(f);
		}
		catch(Exception e)
		{
			t = "";
		}
		
		return t;
	}

	//主函数，测试
	public static void main(String[] args) throws IOException
	{
		String s = FileText.getText("C:/Users/Administrator/Desktop/五子棋/1.g.txt");
		System.out.println(s);
	}
}
