hi friend,

Array is a group of similar type of elements. This is a very important concept of a programming languages that implements the Array variable. It contains the list of elements of similar types.

In Java, size of array is fixed when it is created so we can't add additional value into it. For the variable size of array you would be required to implement the List as ArrayList of java.util.Collection

A simple example of adding element into an array is given as below hope this will helpful for you.

public class AddElement
{
   public static void main(String args[])
    {
        int num = 0;
        int lastNum = 10;
        int[] numArray = new int[lastNum];
        for(int i = 0; i < numArray.length; i++)
         {
            numArray[i] = num;
            num++;
            System.out.print(numArray[i] + " ");
         }
    }
}
