Java string array add element

Java array add element

// A better solution would be to use an ArrayList which can grow as you need it. 
// The method ArrayList.toArray( T[] a ) 
// gives you back your array if you need it in this form.

List<String> where = new ArrayList<String>();
where.add(element);
where.add(element);

// If you need to convert it to a simple array...

String[] simpleArray = new String[ where.size() ];
where.toArray( simpleArray );

Add string to array java

in java, once you declared an array you cannot change its size.
so that adding an element to the array is not possible.
you can declare an arraylist, which is the same as array but its resizable.
meaning that you can add or remove at any time and as much you want.
for example:
ArrayList<String> languages = new ArrayList<String>(); 
languages.add("PHP");
languages.add("JAVA");
languages.add("C#");
ArrayList<int> numbers = new ArrayList<int>(); 
numbers.add(9);
numbers.add(14);
numbers.add(2);
