Creating a Symbolic Link
CreateSymbolicLink.java
import java.io.*;
import java.nio.file.*;
public class CreateSymbolicLink {
public static void main(String[] args) {
Path newLink = Paths.get("test-link");
Path target = Paths.get("Format.java");
try {
Files.createSymbolicLink(newLink, target);
} catch (IOException x) {
System.err.println(x);
}
}

import java.io.*;
import java.nio.file.*;
public class CreateHardLink {
public static void main(String[] args) {

}
Detecting a Symbolic Link
TestSymbolicLink.java
import java.nio.file.*;
public class TestSymbolicLink {
public static void main(String[] args) {
Path file = Paths.get("test-link");
if (Files.isSymbolicLink(file)) {
System.out.println("I am symbolic link!");
} else {
System.out.println("guess wrong!");
}

public static void main(String[] args) {
Path link = Paths.get("test-link");
try {
System.out.format("Target of link '%s' is '%s'%n", link, Files.readSymbolicLink(link));
} catch (IOException x) {
System.err.println(x);
}
}
