quick way to add onto elements in an array code example

Example 1: 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 );

Example 2: how to add to an array

var ar = ['one', 'two', 'three'];
ar[3] = 'four'; // add new element to ar
