求最大值与最小值

[java]代码库

package C;
import java.util.*;
public class maxandmin {
	public static void main(String[] args){
		Scanner out = new Scanner(System.in);
		int[] arr =new int[3];
		for(int j = 0;j < 3;j++){
			System.out.println("请输入一个数");
			arr[j] =out.nextInt();
		}
		int max = arr[0];
		int min = arr[0];
		for(int i = 1;i < 3;i++){
			if(max < arr[i]){
				max = arr[i];
			}
			if(min > arr[i]){
				min = arr[i];
			}
		}
		System.out.println("最大值："+max);
		System.out.println("最小值："+min);
	}
}
