Hello my question is fairly simple though I can't seem to find the solution. I'm writing a program that basically calculates the area of different shapes. I am making a seperate method per shape to do the calculations but in my main method I need to call the method according to what shape it is. I have the program ask which shape, how do i make it call the method the user inputs for?

I have the shapes listed like this :

```
int 1 = triangle;
int 2 = square;
int 3 = rectangle;
int 4 = trapezoid;
int 5 = pentagon;
int 6 = hexagon;
int 7 = octagon;
int 8 = circle;
System.out.println("Enter the number of the shape you are calculating the are of.");
System.out.println("1. Triangle");
System.out.println("2. Square");
System.out.println("3. Rectangle");
System.out.println("4. Trapezoid");
System.out.println("5. Pentagon");
System.out.println("6. Hexagon");
System.out.println("7. Octagon");
System.out.println("8. Circle");
keyboard.nextInt();
```

I have the methods written out, below in the program. I just need to know how to call the method. Any help would be much appreciated.
