Software Engineering I have an idea of how to create a simple Message class with the following features:
It should reside in the package message.
It should contain a private field that holds a message of type String
It should have a public constructor that takes a message of type String and assigns it to the message field
It should override the toString method to print the contents of the message field
However, I cannot remember how to create a JUnit Test case for my message class. I need to create a test case that requires the following:
It should reside in the package message.
It should test at least two different Message objects to see if their toString methods return the correct value.

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.
