Java 實例 - 數組擴容
Java 實例以下實例演示了如何在數組初始化後對數組進行擴容：
Main.java 檔
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);
}
}
}
以上代碼運行輸出結果為：
A B C D E
