//Q. 41:
//Arithmeticmean(ClassesandObjects)
/*
Java program to find arithmetic mean
Mandatory:
1. Create a new class "Mean" and the object name for the class should be "obj"
2. Create two methods as follows:
a. Method name = getMean()
b. Type = void
c. Access Specifier = public
d. Argument Type = no arguments
a. Method name = calculateMean()
b. Type = void
c. Access Specifier = public
d. Argument Type = no arguments
3. Access the methods getMean() and displayMean() using the object name "obj" from the main method
4. The input details are promoted in getMean() and the transpose is calculated and printed in displayMean()
