• Java 实例 - 数组扩容

    以下实例演示了如何在数组初始化后对数组进行扩容:

    Main.java 文件

    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); } } }

    以上代码运行输出结果为:

    A
    B
    C
    D
    E
