Whenever I write a code that includes an ArrayUtil, it causes an unexpected error:
int[] values = ArrayUtil.randomIntArray(30, 300);
I use Eclipse to write my code, and there is always a red underline under “ArrayUtil”. What am I doing wrong?
What package does your ArrayUtil belong to? No one can answer with certainty without that information.
Did you get it here? If yes, your signature looks right. You probably haven’t imported it yet, or the class isn’t in your CLASSPATH. Eclipse is telling you to correct one or the other.
