Question

已知一个int数组, 编程从数组中获取最大数.

Answer 1

public class MaxMin{
public static void main(String[] args){
int[] arr=new int[]{3,4,25,2,6,24,17,23,4,5};
int min,max;
min=max=arr[0];
for(int i=1;i<arr.length;i++)
{
if(min>arr[i])min=arr[i];
if(max<arr[i])max=arr[i];
}
System.out.println("\n数组中的最大数为"+max+"，\n最小数为"+min+"。");
}
}

Answer 2

import java.util.Arrays;
public class MaxMin {
public static void main(String[] args) {
int[] arr = new int[] { 3, 4, 25, 2, 6, 24, 17, 23, 4, 5 };
Arrays.sort(arr);//升序排列
System.out.println("\n数组中的最大数为" + arr[arr.length-1] + "，\n最小数为" + arr[0] + "。");
}
}
