这是我的代码：

import java.util.Scanner;

class Main
{
    public static void main( String[] args ) /*throws IOException*/
    {
         Main myWork = new Main();
         myWork.begin();
    }


    void begin()
    {
        Scanner input = new Scanner( System.in );
        int inputArraySize; // size of array
        int[] inputNumberSequence; // input sequence of numbers saved in array

         while( true )
        {
//            jollyJumpers = new JollyJumpers( inputArraySize );
                        inputArraySize = input.nextInt();
                        inputNumberSequence = new int[ inputArraySize ];

            for( int iii = 0; iii < inputArraySize; ++iii )
            {
                inputNumberSequence[iii] = input.nextInt();
            }

            if( jollyOrNotJolly( inputNumberSequence, inputArraySize ) )
                System.out.println( "Jolly" );

            else
                System.out.println( "Not jolly" );
        }
    }


    boolean jollyOrNotJolly( int[] inputNumberSequence, int inputArraySize )
    {
        int maxInteger = inputNumberSequence[0];
        int minInteger = inputNumberSequence[0];
        int summationOfInputNumberSequence = 0;
        int temporaryElementFromList;
        int summation_From_MinInteger_To_MaxInteger = 0;

        for( int iii = 0; iii < inputArraySize; ++iii )
        {
            temporaryElementFromList = inputNumberSequence[ iii ];

            if( temporaryElementFromList > maxInteger )
                maxInteger = temporaryElementFromList;

            else if( temporaryElementFromList < minInteger )
                minInteger = temporaryElementFromList;

            summationOfInputNumberSequence += temporaryElementFromList;
        }

        for( int jjj = minInteger; jjj <= maxInteger; ++jjj )
        {
            summation_From_MinInteger_To_MaxInteger += jjj;
        }

        return summationOfInputNumberSequence == summation_From_MinInteger_To_MaxInteger;
    }
}

可能已经有点晚了但是我建议在你的代码周围包装一个try-catch块，它可以捕获任何异常，只是打印出来。然后你会得到一个WA错误，你可以开始缩小try-catch，直到你再次遇到Runtime Exception。然后，您可以正确地确定抛出异常的位置。至少就是我这样做的方式，面对的是我最初无法复制的例外情况。
