Find the error

import java.io.File;

public class DetermineFileDirExists {

    private static void doTest() {

        // Create a File object
        File file1 = new File("README_InputFile.txt");
        File file2 = new File("BlaBlaBla.txt");

        boolean b = file1.exists();
        System.out.println();
        System.out.println("Does File/Di " + file1 + " exist? (" + b + ")\n");

        b = file2.exists();
        System.out.println();
        System.out.println("Does File/Di " + file2 + " exist? (" + b + ")\n");


    }


    /**
     * Sole entry point to the class and application.
     * @param args Array of String arguments.
     */
    public static void main(String[] args) {
        doTest();
    }

}

errr, hmm. What was the error message?

[xXHalfSliceXx]

Find the error in the coding.

[WingedPanther]

I'd have to look at a reference, but it looks like you've got a timebomb waiting for you if file1 or file2 does NOT exist. file1 and file2 are not the filenames.

[TkTech]

Erm, I looked through this, and there is none...

[edit]
Proof of concept, I even compiled and ran it, works fine. Haha.

import java.io.File;
public class DetermineFileDirExists {
    private static void doTest() {
        // Create a File object
        File file1 = new File("README_InputFile.txt");
        File file2 = new File("BlaBlaBla.txt");
        boolean b = file1.exists();
        System.out.println();
        System.out.println("Does File/Di " + file1 + " exist? (" + b + ")\n");
        b = file2.exists();
        System.out.println();
        System.out.println("Does File/Di " + file2 + " exist? (" + b + ")\n");
    }
    /**
     * Sole entry point to the class and application.
     * @param args Array of String arguments.
     */
    public static void main(String[] args) {
        doTest();
    }
}

At first glance:
1. You included the proper class
2. You created a proper class header using proper naming conventions
3. You created a proper constructor giving it a private access modifer and making it static allowing you to use the method without having to create an instance of it
4. Proper syntax of a comment
5,6. Proper creation of a File object (which accepts a string, path can either be absolute or relative)
7. You created a variable b of the boolean type which is the correct type because exists() returns a boolean value
8,9. You print out the results with the proper use of string concatenation
10,11,12. Same as 7,8,9 respectivley
13. Close the constructor
14,15,16,17. Proper comment syntax
18. Proper creation of the main method
19. Proroper reference to the doTest() method. No instantiation needed being that doTest() is a static method
20. Closing of the main method
21. Closing of the class

Conclusion: No error

Test conclusion:
No compile errors, no run time errors, works if a file exists and if a file does not exist.

Ill be ****ed if there is an error

edit:
just not sure what the /Di is for

edit:

the error is in the /Di

it is suposed to be pointed to /Dir
Meaning Directory

[Jordan]

Hmm, that is a little hard to guess. How do we know that the creator didn't have a /Di directory?

[xXHalfSliceXx]

thats what i have been saying that I don't really like this example.

Closed. Make a new one.
