List 中的最大最小值
以下实例演示了如何使用 Collections 类的 max() 和 min() 方法来获取List中最大最小值: /* author by w3cschool.cc Main.java */ import java.util.*; public class Main { public static void main(String[] args) { List list = Arrays.asList("one Two three Four five six one three Four".split(" ")); System.out.println(list); System.out.println("最大值: " + Collections.max(list)); System.out.println("最小值: " + Collections.min(list)); } } 以上代码运行输出结果为: [one, Two, three, Four, five, six, one, three, Four] 最大值: three 最小值: Four List<Double> input = new ArrayList<Double>(); input.add(2.3); input.add(3.3); input.add(4.3); input.add(5.3); input.add(6.3); input.add(7.3); input.add(8.3); input.add(9.3); input.add(1.3); System.out.println(input); System.out.println("最大值: " + Collections.max(input)); System.out.println("最小值: " + Collections.min(input)); 以上代码运行输出结果为: [2.3, 3.3, 4.3, 5.3, 6.3, 7.3, 8.3, 9.3, 1.3] 最大值: 9.3 最小值: 1.3
public class MAX { @Test public 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); } }
