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;
