if I want my program to display information (values) but also take user input into the Array using Java, how is it done? Please guide me. When my program starts up, I want to see the values but I also want to allow the user to input value into the array

my code only allows user input but I also want to show values. how do I display values that I've hard coded?

If you want to get an input for an array you need to get the size of array before creating the array. Then you can get input from the system. I have Provided you a sample program which will be useful for you to get inputs for an array. You can refer the java docs for various methods you could use.

 import java.util.Scanner;
    public class Test
    {
        public static void main(String[] args)
        {
            int n;
            Scanner sc=new Scanner(System.in);
            System.out.print("Enter Array Size:");
            n=sc.nextInt();
            int[] array = new int[n];
            System.out.println("Enter Array elements: ");
            for(int i=0; i<n; i  )
            {
                array[i]=sc.nextInt();
            }
    
            for (int i=0; i<n; i  )
            {
                System.out.println(array[i]);
            }
        }
    }  

You need to create the array of your required type and size then you have to get the inputs using a for loop for array elements.
