How to resolve the Java NegativeArraySizeException exception?

The NegativeArraySizeException in Java indicates that an array is being created with a negative size. To fix this exception, ensure that no negative sized arrays are specified in your code.

Here are some ways to resolve the NegativeArraySizeException exception:

1. Check the calculation logic of the array size to ensure that negative sizes do not occur.
2. Add conditional statement to prevent the creation of arrays with negative size.
3. You can use a try-catch block to catch the NegativeArraySizeException and handle it by informing the user to input a valid array size when the exception is caught.
4. Use the Math.abs() method to get the absolute value and avoid negative numbers.

Here is a sample code demonstrating how to handle the NegativeArraySizeException.

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        
        try {
            System.out.println("请输入数组大小：");
            int size = scanner.nextInt();
            
            if (size < 0) {
                throw new NegativeArraySizeException("数组大小不能为负数");
            }
            
            int[] array = new int[size];
            System.out.println("数组创建成功，大小为：" + size);
        } catch (NegativeArraySizeException e) {
            System.out.println("输入的数组大小为负数，请重新输入");
        }
    }
}

In the example above, we use a try-catch block to catch the NegativeArraySizeException and prompt the user to input a valid array size when the exception is caught. This helps prevent the program from throwing an exception due to a negative array size. You can choose an appropriate solution to handle the NegativeArraySizeException based on your specific situation.
