For this assignment, you are to complete the development of the Java class Interval. Each instance of this class represents an interval over the real numbers. For example, the interval [4.3, 8.5] is the set of all real numbers x satisfying 4.3 ≤ x ≤ 8.5.
Most of the class's methods are only stubs and are clearly marked as such. A few methods are provided in full.
The simple nature of the subject matter of this assignment (intervals), together with the detailed method specifications present in the source code provided to you, make it unnecessary to provide any further explanation here.
For the purposes of testing your work, you are encouraged to make use of the Java application IntervalApp.
Use the file submission system in order to submit your source code (i.e., the Interval.java file, not the Interval.class file). Remember to include, within your source code, comments that acknowledge every person who provided assistance to you and comments that describe any deficiencies of which you are aware.
