java - 我需要有关 Java 作业介绍的帮助

Question

我已经成功编译了这个java程序(生成100个0到25之间的随机数，将它们放在一个数组中，并根据每个数组的奇偶性将它们排序到两个不同的数组中)，虽然它没有运行。我怀疑我在其中一个 while 循环中犯了一个错误，尽管我不确定。此外，我努力让问题中的代码格式正确，因此选项卡有些偏离，但它仍然大部分清晰可见。这是 .java 文本:

public class Assignment8
{
    public static void main( String [] args )
    {
        int storage [] = new int[100];
        int j = 0;  

        while ( storage.length < 100 )  {
            int testVariable = 0 + (int) (Math.random() * ((25 - 0) + 1));
            storage[j] = testVariable;
            j++;
        }

        int oddArray[] = OddNumbers( storage );
        int evenArray[] = EvenNumbers( storage );
        int currentNumber = 0;

        System.out.println( "The odd numbers are: " + "\n" );

        while ( currentNumber <= 99 ) {
            System.out.println( oddArray[currentNumber] + "\n" );
            currentNumber++;
        }

        System.out.println( "\n" + "The even numbers are: " + "\n" );
        currentNumber = 0;

        while ( currentNumber <= 99 ) {
            System.out.println( evenArray[currentNumber] + "\n" );
            currentNumber++;
        }
    }

    public static int[] OddNumbers( int storage[] )
    {
        int currentNumber = 0;
        int currentValue = storage[currentNumber];
        int oddArray[] = new int[100];

        while ( currentNumber <= 99 ) {
            if ( storage[currentNumber] % 2 != 0 ) {
                oddArray[currentNumber] = currentValue;
            } else {
                continue;
            }

            currentNumber++;        
        }

        return oddArray;
    }

    public static int[] EvenNumbers( int storage[] )
    {
        int currentNumber = 0;
        int currentValue = storage[currentNumber];
        int evenArray[] = new int[100];

        while ( currentNumber <= 99 ) {
            if ( storage[currentNumber] % 2 == 0 ) {
                evenArray[currentNumber] = currentValue;
            } else {
                continue;
            }

            currentNumber++;        
        }

        return evenArray;
     }
}

storage.length 在整个程序执行期间不会改变，因为数组已经分配。因此，您的第一个 while 循环是错误的，因为 100 不小于 100，它永远不会执行。相反，您可以使用简单的 for 循环:

for (int j  = 0; j < storage.length; ++j) {
    int testVariable = 0 + (int) (Math.random() * ((25 - 0) + 1));
    storage[j] = testVariable;
}
