Delete all files with an extension using Java

Question

I\'m (relatively) new to Java and I\'m trying to implement a .jar that runs a list of commands that in Windows XP\'s command prompt it would be:

cd\\
cd myfolder         


        

Answer 1

fList.get(i) should be fList[i] as fList is an array, and it returns a File reference not a String.

Change: -

String pes = fList.get(i);

to: -

File pes = fList[i];

And then change if (pes.contains(".lck") == true) to
if (pes.getName().contains(".lck"))

In fact, since you are checking for the extension, you should use endsWith method rather than contains method. And yes, you don't need to compare your boolean value with ==. So just use this condition: -

if (pes.getName().endsWith(".lck")) {
    boolean success = (new File(fList.get(i)).delete());
}
