Java读文件夹

使用JAVA读取文件夹中的多个文件

package hx.ReadFile;

import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.File; public class ReadFile {
public ReadFile()
{
}
/**
* 读取某个文件夹下的所有文件
*/
public static boolean readfile(String filepath) throws FileNotFoundException, IOException
{
try{
File file = new File(filepath);
if (!file.isDirectory())
{
System.out.println("文件");
System.out.println("path=" + file.getPath());
System.out.println("absolutepath=" + file.getAbsolutePath());
System.out.println("name=" + file.getName());
}
else if (file.isDirectory())
{
System.out.println("文件夹");
String[] filelist = file.list();
for (int i = 0; i < filelist.length; i++)
{
File readfile = new File(filepath + "\\" + filelist[i]);
if (!readfile.isDirectory())
{
System.out.println("path=" + readfile.getPath());
System.out.println("absolutepath="
+ readfile.getAbsolutePath());
System.out.println("name=" + readfile.getName()); }
else if (readfile.isDirectory())
{
readfile(filepath + "\\" + filelist[i]);
}
} } }
catch (FileNotFoundException e)
{
System.out.println("readfile() Exception:" + e.getMessage());
}
return true;
