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);

}

}
