Material

-name : String

-weight: double

+ Material ()

+ Material (n: String, w : double)

+ setName(n : String): void

+ setWeight(w : double): void

+ getName(): String

+ getWeight(): double

Write a class declaration for Material class and add the two variables to the class declaration

• name: is a String variable that holds the name of the material.
• weight: is a double variable that holds the weight of the material.

2- The class should have the following constructors:

• A constructor that accepts the following value as argument and assigns it to the appropriate fields: material name and weight.
• A no-arg constructor that assigns empty strings ("") to the name, and 0.0 to the weight field.

3- Write mutator methods that store values in these fields and accessor methods that return the values in these fields as in above UML diagram.

4- Once you have written the class, write a separate program that creates two Material objects to hold the following data:

name	weight
Steel	45.8
Wood
