我是java的新手,并且一直在尝试创建一个程序来生成100个数字并对赔率和赔率进行排序。无论我做什么,该程序甚至会给出.class预期的错误。任何帮助将不胜感激。

此行中不需要[]
而不是
int randomNumbers[] = new int[100];
// and
int oddNumbers[] = getOddNumbers(oddCount, randomNumbers[]);
写
int[] randomNumbers = new int[100];
// and
int[] oddNumbers = getOddNumbers(oddCount, randomNumbers);
[]
是类型的一部分,而不是名称。

当引用整个数组时,请不要将[]
与变量名一起使用。变化
int oddNumbers[] = getOddNumbers(oddCount, randomNumbers[]);
int evenNumbers[] = getEvenNumbers(evenCount, randomNumbers[]);
到
int oddNumbers[] = getOddNumbers(oddCount, randomNumbers);
int evenNumbers[] = getEvenNumbers(evenCount, randomNumbers);

正如Peter Lawrey所说,你不需要函数调用上的括号。还有一些其他编译错误。首先,看起来您在getEvenNumbers
函数中有一个复制/粘贴错误。 for循环内oddNumbers
应为evenNumbers
。
您还需要初始化整数oddCount
和evenCount
(可能是0
)。
