Question

Can someone please help with this in JAVA?

Write one application program by using the following requirements:

1) Exception handling

2) Inheritance

a) At least one superclass or abstract superclass: this class needs to have data members, accessor, mutator, and toString methods

b) At least one subclass: this class also needs to have data members, accessor, mutator, and toString methods

c) At least one interface: this interface needs to have at least two abstract methods

d) At least one method overloading

e) At least one method overriding

f) At least one static member and one static method

g) Polymorphism: you need to have at least one superclass reference to reference objects of a subclass

3. Within your application, please include comments at the places where you use the above items.

**This is what I have so far***

public class gatorade {

public void nutrition() {
System.out.println("nutrition facts method");
System.out.println("90 Calories");
System.out.println("0 Grams Fat");
System.out.println("20 MG Sodium");
System.out.println("18 Grams Sugar");
System.out.println("0 Grams Protein");
}
}
//inheritance
public class blueberry extends gatorade{
System.out.println("Color is blue");

public class orange extends gatorade{
System.out.println("Color is orange");

public class lemonlime extends gatorade{
System.out.println("Color is yellow");

public class fruitpunch extends gatorade{
System.out.println("Color is red");

Note: Could you plz go through this code and let me know if u need any changes in this.Thank You
