方法参数是数组
public class ArrayTest { public static void main(String[] args) { //静态数组 //方式1 int[] arr = {100, 200, 300}; printAarray(arr); //方式2 printAarray(new int[]{122, 22, 344}); //动态数组 int[] arra = new int[5]; printAarray(arra);//5个0 } public static void printAarray(int[] arr) { for (int i = 0; i < arr.length; i++) { System.out.println(arr[i]); } } }
