Java 實(shí)例 - 數(shù)組擴(kuò)容
以下實(shí)例演示了如何在數(shù)組初始化后對(duì)數(shù)組進(jìn)行擴(kuò)容:
/* author by w3cschool.cn 文件名:Main.java */ public class Main { public static void main(String[] args) { String[] names = new String[] { "A", "B", "C" }; String[] extended = new String[5]; extended[3] = "D"; extended[4] = "E"; System.arraycopy(names, 0, extended, 0, names.length); for (String str : extended){ System.out.println(str); } } }
以上代碼運(yùn)行輸出結(jié)果為:
A B C D E
