jsp 目录文件操作

jsp教程目录文件操作

file file1 = new file ("c:tempmynote.txt"); // in windows
file file2 = new file ("/tmp/mynote.txt"); // in linux/unix

检测文件路径

import java.io.file;
public class mainclass {
public static void main(string[] a) {
    file myfile = new file("c:" + file.separator + "jdk1.5.0" +

file.separator, "file.java");
    system.out.println(myfile.getname());
    system.out.println(myfile.getpath());
}
}

获取远程图片

import java.io.file;
import java.net.uri;

public class mainclass {
public static void main(string[] a) throws exception {

file remotefile = new file(new uri("file:///index.htm"));
}
}

上级目录

import java.io.file;
public class mainclass {
public static void main(string[] a) {
    file myfile = new file("c:" + file.separator + "jdk1.5.0" +

file.separator, "file.java");
    system.out.println(myfile.getparent());
    system.out.println(myfile);
}
}

判断是否为目录

import java.io.file;
public class mainclass {
public static void main(string[] a) {
file myfile = new file("c:" + file.separator + "jdk1.5.0" +

file.separator, "file.java");
system.out.println(myfile.isdirectory());
}
}

是否为文件

import java.io.file;
public class mainclass {
public static void main(string[] a) {
file myfile = new file("c:" + file.separator + "jdk1.5.0" +

file.separator, "file.java");
system.out.println(myfile.isfile());
}
}
