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() {
}
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;
}
public static void main(String[] args) {
try {
readfile("e:/videos");
// deletefile("D:/file");
} catch (FileNotFoundException ex) {
} catch (IOException ex) {
}
System.out.println("ok");
}
}
