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:
/*

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);
}
}
}
以上代码运行输出结果为:
A
B
C
D
E
