基础编码

public class Test {
public static void main(String[] args) {
File file = new File("D:/myword", "test.txt");
if (file.exists()) {
file.delete();
System.out.println("文件已删除");
} else {
try {
file.createNewFile();
System.out.println("文件已创建");
} catch (Exception e) {
e.printStackTrace();
}
}
}
}

import java.io.File;

public class Test {

String name = file.getName();
long length = file.length();
boolean hidden = file.isHidden();
System.out.println("文件名称：" + name);
System.out.println("文件长度：" + length);
System.out.println("该文件是隐藏文件吗？" + hidden);
} else {
System.out.println("该文件不存在");
