Create a public class named Course. Course should store two pieces of data: a name (as a String) and an enrollment (as an int). Provide a public constructor that allows both fields to be set, with the name first. Following the encapsulation pattern we have introduced, provide both a setter and a getter for the enrollment as getEnrollment and similar. Provide only a getter for the name as getName. Finally, reject negative enrollment values and null names using assert.
