第七章第九题（找出最小元素）（Find the smallest element）

• 7.9（找出最小元素）使用下面的方法头编写一个方法，求出一个整数数组中的最小元素：
  public static double min(double[] array)
  编写测试程序，提示用户输入是个数字，调用这个方法返回最小值，并显示该最小值。下面是该程序的运行示例：
  Enter 10 numbers: 1.9 2.5 3.7 2 1.5 6 3 4 5 2
  The minimum number is 1.5
  7.9（Find the smallest element）Use the following method header to write a method to find the smallest element in an integer array:
  public static double min(double[] array)
  Write a test program, prompt the user to input a number, call this method to return the minimum value, and display the minimum value. The following is an example of how to run the program:
  Enter 10 numbers: 1.9 2.5 3.7 2 1.5 6 3 4 5 2
  The minimum number is 1.5
• 参考代码：

package chapter07;

import java.util.Scanner;

public class Code_09 {
    
    
    public static void main(String[] args) {
    
    
        double[] array = new double[10];
        Scanner input = new Scanner(System.in);
        System.out.print("Enter 10 numbers: ");
        for (int i = 0;i < 10;i++)
            array[i] = input.nextDouble();
        System.out.println("The minimum number is " + min(array));
    }
    public static double min(double[] array){
    
    
        double min = array[0];
        for (int i = 1;i < array.length;i++)
            if (min > array[i])
                min = array[i];
        return min;
    }
}

• 结果显示：

Enter 10 numbers: 1.9 2.5 3.7 2 1.5 6 3 4 5 2
The minimum number is 1.5
