Example 2: how to add elements in string array in java

Arrays in Java have a defined size, you cannot change it later by adding or removing elements (you can read some basics here). Instead, use a List : ArrayList<String> mylist = new ArrayList<String>(); mylist. add(mystring); //this adds an element to the list.
