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:

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);
}
}
