3. public static void main(String[] args)
4. {
5. int[] firstArray = {; //initialized array.
6. int[] secondArray = {11,14,9,5,2,23,15};
7. int length = firstArray.length + secondArray.length; //add the length of firstArray into secondArray.

How do you merge arrays?

1. Create an array arr3[] of size n1 + n2.
2. Simultaneously traverse arr1[] and arr2[]. ...
3. If there are remaining elements in arr1[] or arr2[], copy them also in arr3[].

How do you copy one array into another?
