Java: is there an easy way to select a subset of an array?

Question

I have a String[] that has at least 2 elements.

I want to create a new String[] that has elements 1 through the rest of them. So.. basically, just skipping the first one.

Can this be done in one line? easily?

Answer 1

Use copyOfRange, available since Java 1.6:

Arrays.copyOfRange(array, 1, array.length); 

Alternatives include:

• ArrayUtils.subarray(array, 1, array.length) from Apache commons-lang
• System.arraycopy(...) - rather unfriendly with the long param list.
