Main class and Main function:(I need to get input one by one and display the appended values)
System.out.println("Enter the array value");
Array arrayobj = new Array();
int value = scan.nextInt();
Integer[] valuearr = new Integer[1];
valuearr[0] = value;
arrayobj.add(valuearr);

Account class : (Add method)
public void add(Integer[] a) {
    System.out.println("The values are")
}

May be this will help you. You are trying to add an array of size 1 to a list. You must have a global list in account class to where you add numbers into. And, values must be printed from it. If you want an array to come from main class, you can use add all as below.

 class Account {
       ArrayList<Integer> numbers= new ArrayList<>();

       public void add(Integer[] a) {
         numbers.addAll(Arrays.asList(a));
         System.out.println("The values are")
         for (Integer num : numbers) {            
           System.out.println(num);         
         }
       }
    }

If you want to just append a number and print, can use numbers.add(int_value);

I recommend you to use arrayList instead of array

ArrayList<Integer> arrayobj = new ArrayList<Integer>();

Add and print function would be.

 public void add(Integer[] a) {
 arrayobj.add(a);
 System.out.println("The values are:"+arrayobj );}
