Question

1
Demonstrate the use of local variables in a Java program that has
1 function

2
Demonstrate the use of overloaded methods
each has three primitive parameters
two methods computes and returns the product to the calling method for printing
one method computes and prints the product; does not return a result

3
Demonstrate the use of overloaded constructors
Three constructors each initialize two variables
Three methods, 1 computes the radius of a circle, 1 computes the area of a rectangle, and area of sphere

Answer 1

1)Local Variables: These are the variables declared inside a method, we can use those variables inside the method only.
other method even don;t know about those varibles which are declared in other method... if we try to refer it out of the method it will shows an error...

Output :

2)Method Overloading: Method overloading means creating multiple methods with same name but differ in number
of arguments or type of arguments. If we want to return any value we have to give return type to the method

Output :

3)Constructor Overloading: constructors with same names but differ in number of arguments or type of parameters.
constructor will be automatically called when the object is created for the class.
