If I have a file which has name  name.zz

I want to check

if (name have extension zz)
{
//      Do something
}
else
{
System.out.println(“The file is not a zz file”);
}


Is there a way to check the extension of the file?

I suppose the easiest way is checking that the ".zz" is at the end of the string , which  means that the last index of that is at the string's length - 3, so you get:

   if (name.lastIndexOf(".zz") == name.length - 3)
0
