Shapes

Lab to work on static methods, parameters and return statements.

To Do:

• Think about formulas used to determine the area of various shapes.
  • How many measurements are needed to determine the area?
  • What data type would be best to represent these measurements?
• For example, the area of a square can be determined using the formula: A = s^2.
  • The formula requires one measurement, the side length, to calculate the area.
  • The measurement can be either a whole number, or decimal, so using a double seems appropriate.
• Therefore, a method signature to calculate the area of any square could be:

public static void square(double s){
  //insert code here
}

Part 1:

• Other shapes you may consider:
  • Triangle
    • A = 1/2(bh)
    • Heron's formula
  • Rectangle
  • Circle

---

Part 2:

• Use existing methods to go a step further and determine the volume of 3D-shapes.
  • Cube
  • Triangular Prism
  • Rectangular Prism
  • Sphere
• Think about how these volume formulas relate to the area forumulas you already developed into Java methods.
  • Reuse code when you can!

Extension:

• Include drawing methods that use nested for loops to produce ASCII art shapes.
