Question

public static int getNextLargest(int[] numArray, int searchNum)
    {for(int i:numArray){
       out.println(i);
       if(searchNum < i){
           numArray.add(i);
       }
   }

    return -1;
}

除了将存储在i中的内容添加到数组中之外，它完全符合我的要求。我也尝试了numArray [i]，它也无法工作。

public static int getNextLargest(int[] numArray, int searchNum)
{
  for(int i:numArray){
    //You should use System.out.println.
       System.out.println(i);
    //You are modifying the inputArray in this line
       if(searchNum < i){
    //1. There is no add method on integer, you can use ArrayList of Integers to use add method. ArrayList<Integer> numArray=new ArrayList<Integer>; 
    //2. int[] array will not increase its size automatically. You have use use ArrayList to do this
           numArray.add(i);
       }
   }

    return -1;
}

为什么我的代码不打印出阵列？
