美团笔试 7 的整除问题。来大佬看代码了

考试时，用C++写的，过10%，就去写第二道了，写完第二道，又用java写了下，然而没写完，就没交，来大佬看看，格式没调，大佬凑合着看吧，看看这个能过多少

package demo1;

import java.util.Scanner;

public class Test {

public static void main(String[] args) {

int length = 0;

int i;

int sum=0;

int x;

String s;

Scanner scanner = new Scanner(System.in);

Scanner scanner1 = new Scanner(System.in);

length = scanner.nextInt();

int[] intArray = new int[length];

for (i = 0; i < length; i++) {

intArray[i] = scanner1.nextInt();

}

for (i = 0; i < length; i++) {

for (int j = 0; j < length; j++) {

}

else {

s = String.valueOf(intArray[i]) + intArray[j] + "";

x = Integer.valueOf(s).intValue();

if (x % 7 == 0) {

}

}

}

}System.out.println(sum);

}

}
