arraycopy数组的拷贝

import java.util.Arrays;

public class CopyArray {

	public static void main(String[] args) {
		
		String[] a={"a","b","c","d","e"};
		String[] b=new String[6];
		System.arraycopy(a, 0, b, 0, a.length);
		//System.arraycopy(原数组, 从原数组哪个位置开始拷贝, 目标数组, 目标数组开始位置, 从原数组中多少个元素拷贝到目标数组中);
		System.out.println(Arrays.toString(b));
	}
}
