JAVA之设计一个立方体类Cube,只有边长属性，计算表面积和体积

import java.util.Scanner;

class acube
{
	int s,c;
	public int bmj(int a)//表面积
	{
		s=a*a*6;
		return s;
	}
	public int tj(int a)//体积
	{
		c=a*a*a;
		return c;
	}
}
public class cube {
	public static void main(String[] args) {
		int b,s,tj;
		Scanner s1=new Scanner(System.in);
		System.out.println("请输入正方体的边长:");
		b=s1.nextInt();
		acube one;
		one=new acube();
		s=one.bmj(b);
		tj=one.tj(b);
		System.out.println("面积为:"+s);
		System.out.println("体积为:"+tj);
		

	}

}

运行后结果如下:
