Java I/O - 如何创建绝对路径和相对路径

import java.io.File;

public class MainClass {

  public static void main(String[] args) {

    File absolute = new File("/public/html/javafaq/index.html");
    File relative = new File("html/javafaq/index.html");

    System.out.println("absolute: ");
    System.out.println(absolute.getName());
    System.out.println(absolute.getPath());

    System.out.println("relative: ");
    System.out.println(relative.getName());
    System.out.println(relative.getPath());
  }
}
