求两个一个int，一个float数组最大值

Question

用java中的方法重载（一个int，一个float）和for循环求一个数组中的最大值，要求数组中都是正数

Answer 1

取数组最大值，重载函数就是换一个返回值。

import java.util.Scanner;

public class Main {
    public static float Max (float [] arrs){
        float max = arrs[0];
        for(int i = 0;i<arrs.length;i++){
            if(arrs[i]>max){
                max =arrs[i];
            }
        }
        return max;
    }
    public static Integer Max (Integer [] arrs){
        int max = arrs[0];
        for(int i = 0;i<arrs.length;i++){
            if(arrs[i]>max){
                max =arrs[i];
            }
        }
        return max;
    }
    public static void main(String args[]){
        Integer []arrs = new Integer[] {1,2,3
        };
        float []arrsFloats = new float[] {1F,2F,3F
        };


        System.out.println(Max(arrs));
        System.out.println(Max(arrsFloats));
    }
}
