数组或者list最大值最小值

public class MAX {    @Testpublic void test() {int[] arr={1,2,43,45,6,96,2}; int max=-1; int min=-1; for (int i = 0; i < arr.length; i++) { int temp = arr[i]; if(i == 0) { max = temp; min = temp; } if (temp > max) { max = temp; } if (temp < min) { min = temp; } }System.out.println("min is:"+min); System.out.println("max is:"+max); }    }
