合并两个数组

如果要将两个数组合并，也许有很多方法，这里给出一个比较简便的解决方案：

import java.util.*;

public class HeBingArrayTest {
	public static void main(String[] args) {
		String[] a = {"a","aa","aaa"};
		String[] b = {"b","bb","bbb"};
		String[] c = new String[a.length + b.length];
		
		//方法一
		List<String> list = new ArrayList<String>(Arrays.asList(a));
		list.addAll(Arrays.asList(b));
		Object[] tmpCards = list.toArray();
		for(int i = 0; i < tmpCards.length;i ++) {
			System.out.println(tmpCards[i]);
		}
		
		//方法二
		System.arraycopy(a,0,c,0,a.length);
		System.arraycopy(b,0,c,a.length,b.length);
		for(int i = 0;i <c.length;i ++) {
			System.out.println(c[i]);
		}
	}
}

果然简单粗暴
