Adding array values from one integer array to an another

Question

Please help to resolve the below inquiry. There are 2 classes (Main & Account)

In main class, I am getting scanner input value and passing this value as a integer array to account class. In Account class, I need to read this array and display the values.

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")
}

*My input and output should be like this..

@Pavithra why are you using an integer array to send only 1 number? — Gimhani

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);

Hi Gimhani,Thanks for the response. I have tried the above code in Account class but i was able to print only one value and its not printed the previously entered values. Is it due to the array size is 1 in main class as following : 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);

@Pavithra Hi why are you using an Array type object? I thought you need to have an Account object and then call its add method.

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 );}

Hi Orgil, Thanks so much for the response. I have added array to the list as you advised but i was able to print the values whatever i entered and its not printed the previous entered values. public void add(Integer[] a) { for(int i=0;i<a.length;i++) { list.add(a[i]); } System.out.println("The values are"); for(Integer result : list) System.out.println(result);
