Java不输出或请求键盘输入

我很难让我的java代码正确地输出所需的结果。更不用说我的System.out.Println没有提示输入。我所有的代码都很好，没有错误。然而，它似乎没有输出任何东西或请求输入

问题是在psvm方法和下面的代码段中没有任何内容

Scanner scan = new Scanner(System.in);
        int myNum[] = new int[5];
        int i;
        int sum = 0;
        for (i = 0; i < myNum.length; i++) {
            System.out.print("Enter the number " + (i + 1) + " : ");
            myNum[i] = scan.nextInt();
        }

        for (i = 0; i < myNum.length; i++) {
            System.out.print("The number " + (i + 1) + " : ");
            System.out.print(myNum[i] + "\n+");

            for (int e = 1; e <= i; e++) {
                sum = sum + e;
            }
            System.out.println(sum);
        }

Scanner scan=新的扫描仪（System.in）；
int myNum[]=新int[5]；
int i；
整数和=0；
对于（i=0；i例如（int e=1；e在课程结束时把东西放在
{Scanner…}
并把
main
放在它所属的地方spublic static void main（String[]args）{}只是执行…没什么：-）谢谢！我感谢你的帮助。@A.Duffy，如果我的答案解决了你的问题，别忘了投票并为社区接受答案。
