Question

java定义一个三角形类（Triangle）,成员变量是三条边的长度,定义方法perimeter()求周长

Answer 1

class Triangle{

inta,b,c,l;

public static void perimeter(){

l=a+b+c;

}

}

public class TriangleTest{

public static void main(String[] args){

Triangle t1= new Triangle();

t1.a=x;

t1.b=y;

t1.c=z;

t1.perimeter();

System.out.println("三角形t1的周长为："+t1.l);

}

}
