在控制檯輸入舉行場合寬並求出其周長和麪積

import java.util.Scanner;
public class qiujuxing {
public static void main(String args[]) {
Scanner x = new Scanner(System.in);
System.out.print("請輸入矩形長：");
double a;
a = x.nextInt();
Scanner y = new Scanner(System.in);
System.out.print("請輸入矩形寬：");
double b;
b = y.nextInt();
double zhouchang = (a + b) * 2;
double mianji = a * b;
System.out.println("該矩形的周長爲：" + zhouchang);
System.out.println("該矩形的面積爲：" + mianji);
}

}
