I had written a code to show a billboard program and I wanted to prevent the system from crashing by using an
IndexOutOfBoundsException when users enter an invalid choice. I can’t seem to get it to run properly.
Here is what I have:
if (index <= messages.size()) this.text = messages.get(index - 1); else throw new IndexOutOfBoundsException("Invalid Number Choice");
Here is my error:
Exception in thread “main” java.lang.RuntimeException: Uncompilable source code – constructor IndexOutOfBoundsException in class java.util.IndexOutOfBoundsException cannot be applied to given types;
required: no arguments
reason: actual and formal argument lists differ in length.
I really don’t know where to go from here. I tried try/catch and I can’t use the
IndexOutOFBoundsException which I wanted to use because I have another
Class I’m calling.
Good that you are using a StringIndexOutOfBoundsException.
However, I should mention that based on your error ” Uncompilable source code – constructor IndexOutOfBoundsException in class java.util.IndexOutOfBoundsException” You must have imported a different exception Class it should be java.lang.IndexOutOfBoundsException
