以下是实现的代码：
package com.borland.samples.welcome.
import java.io.FileNotFoundException.
import java.io.IOException.
import java.io.File.
public class ReadFile {
public ReadFile() {}
/**
* 删除某个文件夹下的所有文件夹和文件
* @param delpath String
* @throws FileNotFoundException
* @throws IOException
* @return boolean
*/
public static boolean 0deletefile(String delpath) throws FileNotFoundException,
IOException {
try {
File file = new File(delpath).
if (!file.isDirectory()) {
System.out.println("1").
file.0delete().
}
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()).

System.out.println("删除文件成功").
}
else if (delfile.isDirectory()) {

}
}
file.0delete().
}
}
catch (FileNotFoundException e) {
System.out.println("0deletefile() Exception:" e.getMessage()).
}
return true.
}
