Java有一个路径连接方法吗？ [英] Does Java have a path joining method?

问题描述

完全重复：

在java中合并路径 p>

我想知道在Java中是否有这样的方法。以这个片段为例：

$ p $ //这将输出一个/ b
System.out.println（path_join 一， b））;
// a / b
System.out.println（path_join（a，/ b）;


解决方案

引用对同一个问题的好的答案：

如果你以后需要返回字符串，可以调用getPath（）。真的很想模仿Path.Combine，你可以写一些东西：

  public static String combine（String path1，String path2） {
文件file1 =新文件（path1）; 
文件file2 =新文件（file1，path2）; 
返回file2.getPath（）; 
}

combine paths in java

I would like to know if there is such a method in Java. Take this snippet as example :

// this will output a/b
System.out.println(path_join("a","b"));
// a/b 
System.out.println(path_join("a","/b");

解决方案

To quote a good answer to the same question:

If you want it back as a string later, you can call getPath(). Indeed, if you really wanted to mimic Path.Combine, you could just write something like:

public static String combine (String path1, String path2) {
    File file1 = new File(path1);
    File file2 = new File(file1, path2);
    return file2.getPath();
}
