Java: is there an easy way to select a subset of an array?
Solution 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.
Solution 2:
String[] subset = Arrays.copyOfRange(originalArray, 1, originalArray.length);
See Also:
- java.util.Arrays
Solution 3:
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.
