Java 中的路径解析方法，示例

原文:https://www . geesforgeks . org/path-resolvesibling-method-in-Java-with-examples/

resolveSibling()Java . nio . file . path的方法，用于根据该路径的父路径解析给定路径..

有两种类型的 resolveSibling()方法。

resolveSibling(Path other) method of java.nio.file.Path used to resolve the given path as parameter against this path’s parent path. This is very useful where a file name needs to be replaced with another file name. For example, suppose that the name separator is “/” and a path represents “drive/newFile/spring”, then invoking this method with the Path “plugin” will result in the Path “drive/newFile/plugin”. If this path does not have a parent path or other is absolute, then this method returns others. If other is an empty path then this method returns this path’s parent, or where this path doesn’t have a parent, the empty path.

语法:

```java default Path resolveSibling(Path other)

```

参数:该方法接受单个参数其他，这是针对该路径的父路径进行解析的路径。

返回值:此方法返回结果路径。

下面的程序说明了解析(路径其他)方法: 程序 1:

```java // Java program to demonstrate // Path.resolveSibling(Path other) method

import java.nio.file.Path; import java.nio.file.Paths; public class GFG {     public static void main(String[] args)     {

// create object of Path         Path path             = Paths.get("drive\temp\Spring");

// create an object of Path         // to pass to resolve method         Path path2             = Paths.get("programes\workspace");

// call resolveSibling()         // to create resolved Path         // on parent of path object         Path resolvedPath             = path.resolveSibling(path2);

// print result         System.out.println("Resolved Path "                            + "of path's parent:"                            + resolvedPath);     } } ```

Output: 2. resolveSibling(String other) method of java.nio.file.Path used to converts a given path string which we passed as parameter to a Path and resolves it against this path’s parent path in exact same manner as specified by the resolveSibling method.

语法:

```java default Path resolveSibling(String other)

```

参数:该方法接受单个参数其他，这是针对该路径的父路径解析的路径字符串。

返回值:此方法返回结果路径。

异常:如果路径字符串无法转换为路径，该方法抛出invaliddathexception。

下面的程序说明了 resolveSibling(String other)方法: 程序 1:

```java // Java program to demonstrate // Path.resolveSibling(String other) method

import java.nio.file.Path; import java.nio.file.Paths; public class GFG {     public static void main(String[] args)     {

// create an object of Path         Path path             = Paths.get("drive\temp\Spring");

// create a string object         String passedPath = "drive";

// call resolveSibling()         // to create resolved Path         // on parent of path object         Path resolvedPath             = path.resolveSibling(passedPath);

// print result         System.out.println("Resolved Path of "                            + "path's parent:"                            + resolvedPath);     } } ```

Output:
