Java数组排序代码报错求助：在JDoodle运行程序时出现问题

Hey there! I totally get how frustrating it is when your Java code for generating a random integer array and sorting it throws errors and you can’t pin down the root cause—been stuck in that exact spot more times than I care to admit.

To help you diagnose this quickly, could you share a few key details?

• The full code snippet you’re running (make sure to wrap it in backticks so it’s formatted properly!)
• The exact error message or stack trace you’re seeing in JDoodle—copy-pasting the full text will be way more helpful than a vague description
• The Java version you’ve selected in JDoodle’s settings (different versions can have subtle behavior differences)

For context, common issues with this kind of code often include:

• Forgetting to initialize the array before trying to populate it
• Off-by-one errors when defining the range for random integers
• Misusing sorting methods (like forgetting to import java.util.Arrays before calling Arrays.sort())
• Logical bugs in custom sorting implementations, if you’re not using the built-in sort

Once you share those details, I can walk through the code with you to spot the problem and fix it up!
