Why am I getting the error: Incompatible Type

So I am going through the Java tutorial on Oracle' site and I have hit another bump.

Code:

---

import java.io.File;
import java.io.*;
import java.util.Date;

public class Test {
        public static void main(String[] args) throws NullPointerException, IOException {
               
       
        //Testing the setLastModified()
        File e =        new File("xanadu.txt").setLastModified(new Date().getTime());
        }
}

---

I cut out the unimportant part. The question is why am I getting the error: incompatible type:

Code:

---

----jGRASP exec: javac -g Test.java

Test.java:66: error: incompatible types
        File e =        new File("xanadu.txt").setLastModified(new Date().getTime());
                                                              ^
  required: File
  found:    boolean
1 error

 ----jGRASP wedge2: exit code for process is 1.
 ----jGRASP: operation complete.

---

I copied this code from the tutorial after thinking that I typed it wrongly and somehow missed something.

Would you point me in the right direction please? Thanks!

Read the API doc for the setLastModified() method. What does it return?
What is on the left side of the assignment operator?

Break your chained method calls up into single steps.

Sweet. You're the man Norm. It worked. See code below.

Code:

---

File e =        new File("xanadu.txt");
       
        boolean ex = e.setLastModified(new Date().getTime());
       
        System.out.println(ex);

I am now wondering what would be the way to chain the methods and get the desired result? The tutorial had it as one last, but There was no declaration, so I don't know the type on the left of the left hand side.

I personally do NOT like chaining. It doesn't save you any execution time and it can be confusing and cause problems like you just had.

Got it. thanks.
