相当于PHP中的PHP'array_splice'

Question

如何在java

中实现array_splice()

$input = array("red", "green", "blue", "yellow");
array_splice($input, 2);
// $input is now array("red", "green")

Answer 1

Java等价物是List.subList(int, int)。

Answer 2

您可以使用Arrays.copyOfRange(sourceArray, start, end);。

String[] anArray = new String[] { "red", "green", "blue", "yellow" };
String[] subset = Arrays.copyOfRange(anArray, 0, 2);
