如何为主类制作UML图?我不知道哪个是属性和操作。我不知道哪个属性和操作是公共的还是私有的。这是代码:
public class Assignment {
public static void main(String[] args) {
double pi = 3.14159;
int radius;
Area Ar1 = new Area();
Scanner scanner = new Scanner(System.in);
System.out.println("Choose which shape you want to calculate; \n1 Parallelogram \n2 Circle");
Ar1.setShape(scanner.nextInt());
switch (Ar1.getShape()){
case 1:
System.out.println("Insert length");
Ar1.setLength(scanner.nextInt());
System.out.println("Insert width");
Ar1.setWidth(scanner.nextInt());
System.out.println("Area: " + Ar1.getLength() * Ar1.getWidth());
break;
case 2:
System.out.println("Insert radius");
radius = scanner.nextInt();
System.out.println("Area: " + pi * (radius * radius));
break;
default:
System.out.println("ERROR: Please choose something else");
}
}
}

自从我使用UML已经有一段时间了,即使我这样做,我也不是很严格。
由于该类没有属性且方法是静态的,您只需添加类名和方法名(除非您不计算UML中的静态方法)。
