JAVA小练习122——数组工具类的一些补充方法

import java.util.Arrays;
import java.util.List;




public class Demo122 {

	public static void main(String[] args) {
		int[] arr= {10,19,66,88};
		int [] newArr=Arrays.copyOf(arr, 10);
		System.out.println("新数组元素："+Arrays.toString(newArr));
		newArr=Arrays.copyOfRange(arr, 1, 3);//1---2+1
		System.out.println("新数组元素："+Arrays.toString(newArr));
		System.out.println("对应位置上元素一致吗："+Arrays.equals(arr,newArr));
		
		Integer [] arr1= {12,22,55,100};
		List<Integer> list=Arrays.asList(arr1);
		System.out.println(list);
