Someone help me how to print this in last line JAVA ARRAYS AND LOOPS FUNCTION

I am having a trouble printing the last line and I do not how it will be printed. can someone help me to solve this problem? i have a source code atleast and you can refer it to output of source code and possible output.

Source code:

    import java.util.*; 
class Main{ 
  

public static int getfrequentelement (int[]a)
{
  int count = 1, tempCount;
  int popular = a[0];
  int temp = 0;
  for (int i = 0; i < (a.length - 1); i++)
  {
    temp = a[i];
    tempCount = 0;
    for (int j = 1; j < a.length; j++)
    {
      if (temp == a[j])
        tempCount++;
    }
    if (tempCount > count)
    {
      popular = temp;
      count = tempCount;
    }
    
  }
  
  return popular;
}

public static void main (String[] args) 
{ 
    
  Scanner x = new Scanner(System.in);
      System.out.print("Enter the number of frequent flyers: ");
      int size1 = x.nextInt();
      int[] a = new int[size1];
      System.out.print("Enter the frequent flyers: ");
      
      
      for(int i=0; i<a.length; i++) 
      {
        a[i] = x.nextInt();
      }
        
      
      System.out.println("Most frequent = "+getfrequentelement(a));

      
    

}
}

Output of source code:

Enter the number of frequent flyers: 6
Enter the frequent flyers: 7 7 7 9 9 9
Most frequent = 9

Expected Output:

Enter the number of frequent flyers: 6
Enter the frequent flyers: 7 7 7 9 9 9
None

Thank you, i hope you can solve it

>Solution :

You must make your method getfrequentelement(int[]a) static, because you cannot call a non-static method in a static method.

public static int getfrequentelement (int[]a)
{
  int count = 1, tempCount;
  int popular = a[0];
  int temp = 0;
  for (int i = 0; i < (a.length - 1); i++)
  {
    temp = a[i];
    tempCount = 0;
    for (int j = 1; j < a.length; j++)
    {
      if (temp == a[j])
        tempCount++;
    }
    if (tempCount > count)
    {
      popular = temp;
      count = tempCount;
    }
  }
  
  return popular;
}
