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

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?

Use copyOfRange, available since Java 1.6:

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

Stream API could be used too:

String[] array = {"A", "B"};

Arrays.stream(array).skip(1).toArray(String[]::new);

However, the answer from Bozho should be preferred.

String[] subset = Arrays.copyOfRange(originalArray, 1, originalArray.length);
