The ZipCode Class

1. the attributes
   • String fiveDigit
   • String plus4

The App class

1. create 2 ZipCode objects called z1 and z2.
   1. z1 data
      • fiveDigit - "90210"
      • plus4 - "" (blank, no spaces)
   2. z2 data
      • fiveDigit - 16802
      • plus4 - 1503
2. display all the data from each object
   1. if the second attribute, plus4, is blank, display only the first attribute fivedigit
      • for instance, 16801
   2. if the second attribute, plus4, is not blank,
      • display only the first attribute fivedigit followed by a "-" and then the plus4 attribute
        • for instance, 16802-1503
   3. make sure you display the data using the objects z1 and z2
      • A statement using a fixed string is not a correct answer
        • System.out.println("16802-1503"); is not the answer
      • looking at the data and having specific "system.out" is not the correct answer
      • You need to use if statements (or other kind of tests) to handle any variable/object

Output
