因此，我的代码无法运行a[j]=sc.nextInt()

Question

类测试10｛

static double displaySalesObject(String id , double amount) {
return amount;
}

public static void main (String[] args) {
sales s1 = new sales ();
sales s2 = new sales ();

System.out.print(s1.getsalesid() + "," + s1.getamount());
System.out.print(s2.getsalesid() + "," + s2.getamount());
s1.determineDiscount();
s2.determineDiscount();
//}
//public static void main(String args[]) {
//  public void displaySalesArray(){        
//Scanner sc=new Scanner(System.in);
int[] a=new int[6];
System.out.println("Please enter elements...");
for(int j=0;j<6;j++)
//a[j]=sc.nextInt();
System.out.println("Array elements are : ");
for (int i=0;i<a.length;i++)
System.out.println(a[i]);
}

}

**我试着用这个方法通过数组。这是正确的使用方式吗？并且在a[j]=sc.nextInt((处也有错误；**

这就是您想要的吗？

public class Test {
static double displaySalesObject(String id, double amount) {
return amount;
}
public static void main(String[] args) {
sales s1 = new sales();
sales s2 = new sales();
System.out.print(s1.getSalesid() + "," + s1.getAmount());
System.out.print(s2.getSalesid() + "," + s2.getSalesid());
s1.determineDiscount();
s2.determineDiscount();
System.out.println("Please enter elements...");
Scanner sc = new Scanner(System.in);
int[] a = new int[6];
passArrayToTheMethod(sc, a);
}
private static void passArrayToTheMethod(Scanner sc, int[] a) {
for (int j = 0; j < 6; j++)
a[j] = sc.nextInt();
System.out.println("Array elements are : ");
for (int i = 0; i < a.length; i++)
System.out.println(a[i]);
}
}
