Java 程序查找平行四边形面积

编写一个 Java 程序，通过示例查找平行四边形的面积。此示例允许我们输入平行四边形的底和高，两者相乘即可得到面积。因此，面积等于底乘以高。

import java.util.Scanner;

public class Example {
	private static Scanner sc;

	public static void main(String[] args) {
		double pgbase, pgheight, pgArea; 
		sc = new Scanner(System.in);
		
		System.out.print("Please Enter the Base =  ");
		pgbase = sc.nextDouble();
		
		System.out.print("Please Enter the Height = ");
		pgheight = sc.nextDouble();

		pgAr = pgbase * pgheight;

		System.out.format("The Area = %.2f",pgAr);
	}
}

Please Enter the Base =  27
Please Enter the Height = 19
The Area = 513.00

在此 程序 中，我们声明了一个返回平行四边形面积的 ParallelogramArea 函数。

import java.util.Scanner;

public class AreaOfParallelogram2 {
	private static Scanner sc;

	public static void main(String[] args) {
		float pgbase, pgheight, pgArea; 
		sc = new Scanner(System.in);
		
		System.out.print("Please Enter the Parallelogram Base =  ");
		pgbase = sc.nextFloat();
		
		System.out.print("Please Enter the Parallelogram Height = ");
		pgheight = sc.nextFloat();

		pgArea = ParallelogramArea(pgbase, pgheight);

		System.out.format(" The Area of a Parallelogram = %.2f",pgArea);
	}
	
	public static float ParallelogramArea(float pgbase, float pgheight) {
		return pgbase * pgheight;
	}
}
