ex:
Suppose you are a landscape architect who charges $5,000 per mile to landscape a highway, and suppose you know the length in feet of the high way you are working on. Write a Java program to calculate the price you charge when the length is 6000 and 4000, respectively.
Hint: There are 5280 feet in a mile.

Homework 9/19/2008
1. Explain bytecode, JVM
The java compiler translates your program into a language called byte-code,which is the machine language for a fictitious computer.It is easy to translate this byte-code into the machine language of any particular computer.Each type of computer will have its own interpreter that translates and executes byte-code instructions.
Byte-code is the machine language for a fictitious computer called the Java Virtual Machine.
2. Explain class, object
Object-orirnted programming has its own specialized terminology.The object are called,appropriately enough,object.Object of the same kind are said to have the same type or,more often,are said to be in the same class.
3. Reading Assignments:
