// 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 );java add element to existing array
//original array
String[] rgb = new String[] {"red", "green"};
//new array with one more length
String[] rgb2 = new String[rgb.length + 1];
//copy the old in the new array
System.arraycopy(rgb, 0, rgb2, 0, rgb.length);
//add element to new array
rgb2[rgb.length] = "blue";
//optional: set old array to new array
