寻找三个数字的平均数的Java程序

编写一个Java程序，使用+和/算术运算符找到三个数字的平均值。首先，它接受三个双数类型的数字，然后使用算术加号将它们相加，并使用/运算符找到平均值。

package RemainingSimplePrograms;

import java.util.Scanner;

public class AvgOfThree1 { 
private static Scanner sc; 
public static void main(String\[\] args) { 
        sc = new Scanner(System.in);

	System.out.print("Please Enter the first Number = ");
	double num1 = sc.nextDouble();
	
	System.out.print("Please Enter the Second Number = ");
	double num2 = sc.nextDouble();
	
	System.out.print("Please Enter the Third Number = ");
	double num3 = sc.nextDouble();
	
	double average = (num1 + num2 + num3)/ 3;
	System.out.println("\\nThe Average of Three Numbers = " + average);
}

在这个Java例子中，我们创建了一个calAvg函数，找到并返回三个数字的平均值。

package RemainingSimplePrograms;

import java.util.Scanner;

public class AvgOfThree2 { 
private static Scanner sc; 
public static void main(String\[\] args) { 
        sc = new Scanner(System.in);

	System.out.print("Please Enter the first = ");
	double num1 = sc.nextDouble();
	
	System.out.print("Please Enter the Second = ");
	double num2 = sc.nextDouble();
	
	System.out.print("Please Enter the Third = ");
	double num3 = sc.nextDouble();
	
	double average = calAvg(num1, num2, num3);
	System.out.println("\\nThe Average = " + average);
}

public static double calAvg(double a, double b, double c) {
	return (a + b + c)/3;
}

Please Enter the first = 99
Please Enter the Second = 124.7
Please Enter the Third = 33.89

The Average = 85.86333333333333
