Java: Slice Array To End
提问by Mike
I have a string array with at least three elements. I'd like to copy the third and all subsequent elements into a new array. How can this be most efficiently achieved?
我有一个至少包含三个元素的字符串数组。我想将第三个和所有后续元素复制到一个新数组中。如何才能最有效地实现这一目标？
回答by Kevin Bowersox
String[] arr = {"One", "Two", "Three", "Four", "Five"};
String[] arr2 = Arrays.copyOfRange(arr, 2, arr.length);
//Note third param is exclusive
