java读取某个文件夹下的所有文件

学习java基础知识，读取文件，读取某个文件夹，需要读取所有文件，如何实现呢，看下实例代码。

实例代码：

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;

}

/**

* 删除某个文件夹下的所有文件夹和文件

*/

/*public static boolean deletefile(String delpath)

throws FileNotFoundException, IOException {

try {

File file = new File(delpath);

if (!file.isDirectory()) {

System.out.println("1");

file.delete();

} else if (file.isDirectory()) {

System.out.println("2");

String[] filelist = file.list();

for (int i = 0; i < filelist.length; i++) {

File delfile = new File(delpath + "\\" + filelist[i]);

if (!delfile.isDirectory()) {

System.out.println("path=" + delfile.getPath());

System.out.println("absolutepath="

+ delfile.getAbsolutePath());

System.out.println("name=" + delfile.getName());

delfile.delete();

System.out.println("删除文件成功");

} else if (delfile.isDirectory()) {

deletefile(delpath + "\\" + filelist[i]);

}

}

file.delete();

}

} catch (FileNotFoundException e) {

System.out.println("deletefile() Exception:" + e.getMessage());

}

return true;
