There are three person objects, john, mary and jane, sharing a piggy bank of $1000. The Person class contains a double field for the piggy bank. Implement a Java program to instantiate the three objects as follows: Person john = new Person( ); Person mary = new Person( );
Person jane = new Person( );
This Person class also has two methods: one is to withdraw money and the other is to check balance of the piggy bank. Balance checking will return a double primitive value. Provide another class MyProg to start the program execution. In the main method, you should model the following behavior by using the methods. First, John took $75 out of the piggy bank and then viewed the balance. Mary later took away $150. John again withdrew another $120. Finally, Jane checked the balance of the piggy bank. Your program should print out the result for each balance checking. (2.5 pts) Show the UML class diagram for the Person class.
