Where to use resolve() and relativize() method of java.nio.file.Path class?

Question

Path p1 = Paths.get(\"/Users/jack/Documents/text1.txt\");
Path p2 = Paths.get(\"/Users/jack/text2.txt\");
Path result1 = p1.resolve(p2);
Path result2 = p1.relativize(p2)         


        

Answer 1

The resolve(Path) is a method for creating a new Path by joining an existing path to the current path.

Path path1 = Paths.get("/test1/../test2");
Path path2 = Paths.get("test3");
System.out.println(path1.resolve(path2));

The result will be: /test1/../test2/test3

In fact, the method relativize(Path) is used for constructing the relative path from one Path object to another:

Path path1= Paths.get("E:\\test1");
Path path2= Paths.get("E:\\test2\\test3");
System.out.println(path1.relativize(path2));
System.out.println(path2.relativize(path1));

The result will be:

..\test2\test3  relative path from path1 to path2
..\..\test1     relative path from path2 to path1
