Java OCA OCP Practice Question 2902

Question

Assuming the directories and files referenced here all exist and are accessible within the file system, what is the result of the following code? 

Path path1 = Paths.get("/data/./").resolve(Paths.get("sql.txt")); 
Path path2 = new File("/data/././actions/../sql.txt").toPath(); 
? 
System.out.print(Files.isSameFile(path1,path2)); 
System.out.print(" "+path1.equals(path2)); 
System.out.print(" "+path1.normalize().equals(path2.normalize()));
  • A. true true true
  • B. false false false
  • C. false true false
  • D. true false true
  • E. true false false
  • F. The code does not compile.


D.

Note

The code compiles and runs without issue, so F is incorrect.

The one thing to notice about these paths is that they represent the same path within the file system.

Therefore, isSameFile() would return true and B and C are incorrect.

The second output is false, because Path.equals() does not resolve the path within the file system, so A is incorrect.

Finally, the normalized paths are equals(), since all extra symbols have been removed; therefore D is correct and E is incorrect.
