exception java.io.IOException is never thrown in body of corresponding try statement

[Bud Tippins]

I'm getting an error "exception java.io.IOException is never thrown in body of corresponding try statement" on line #16.

What is wrong with my code? Any insights appreciated. Thank you.

package practice2;

import java.io.*;

public class Practice2 {

    public static void main(String[] args) {
        Practice2 p2 = new Practice2();
        p2.go();
    }
    
    void go() {
        try {
            File myDir = new File("myDir");
            myDir.mkdir();
        } catch(IOException e){ }
    }
}

Have a look at the Javadocs for the File class. What exceptions can the constructor and mkdir throw?

It's saying that catching an IOException is unnecessary because none of the code in the try block ever throws an IOException. In other words you don't need to surround lines 14 and 15 in a try/catch.

Thanks guys. Based on your comments I got it fixed.

If you wanted to use try catch then use Exception instead of IOException.

Welcome to the Ranch h:)

I wouldn't try to catch any exceptions there. I don't like catch (Exception ex) ... because it is too non‑specific.
