两个数字相乘的Java程序

用一个例子编写一个两数相乘的Java程序。这个例子接受两个整数值并将这些数字相乘。接下来，println语句将打印这些数值的乘积输出。

package SimpleNumberPrograms。

import java.util.Scanner;

public class MultiplyTwoNumbers { private static Scanner sc;

public static void main(String\[\] args) {
	int Number1, Number2, product;
	sc = new Scanner(System.in);
	
	System.out.print("Enter the First integer Value =  ");
	Number1 = sc.nextInt();

	System.out.print("Enter the Second integer Value = ");
	Number2 = sc.nextInt();
	
	product = Number1 \* Number2;
	System.out.println("\\nProduct of the two integer values = " + product);
}

在这个例子中，productofTwo函数接受两个双倍的值，并返回这两个值的乘法。

package SimpleNumberPrograms;

import java.util.Scanner;

public class MultiplyTwoNumbers2 { private static Scanner sc;

public static void main(String\[\] args) {
	double Number1, Number2, product;
	sc = new Scanner(System.in);
	
	System.out.print("Enter the First =  ");
	Number1 = sc.nextDouble();

	System.out.print("Enter the Second = ");
	Number2 = sc.nextDouble();
	
	product = productofTwo(Number1, Number2);
	System.out.println("\\nProduct of two float values = " + product);
}

public static double productofTwo(double a, double b) {
	return a \* b;
}

Enter the First =  19.5
Enter the Second = 33.2

Product of two float values = 647.4000000000001
