数组的排序和复制的类库

public class ArrayDemo {
	public static void main(String args[]) {

		/*
		//数组指定位置的复制
		int dataA [] = new int [] {1,2,3,4,5,6};
		int dataB [] = new int [] {7,8,9,10,11};

		System.arraycopy(dataA,1,dataB,1,2);//源，复制开始位，目，目开始复制位，长
		print(dataB);
		*/


		//数组排序库函数
		int dataA [] = new int [] {9,8,7,4,5,6,2};
		java.util.Arrays.sort(dataA);
		print(dataA);

	public static void print(int arr[]) {
		for (int x = 0; x < arr.length; x++) {
			System.out.print(arr[x] + ",");
