Float double big problem

Question

New to java.
Heres a perplexing issue:
     private Float lengthInFeet;
     private Integer lengthInInches;
     public void calcLengthInFeet()     
          lengthInFeet = lengthInInches * 1.0 / 12.0;
compile error:
incompatible types
found : double
required: java.lang.Float
lengthInFeet = lengthInInches * 1.0 / 12.0;
What am I doing wrong?
Thanks,
sb

Answer 1

You are mixing primitive types and class types.
You need to know the difference.
To create a new Float object, you have to use the new operator.
Try reading the section on variable types in the online tutorial:
http://java.sun.com/docs/books/tutorial/java/nutsandbolts/variables.html
You can also fix this single problem by changing the class types to primitive types, like this:
private double lengthInFeet;
private int lengthInInches;However, unless you learn/understand the distinction between the types, you won't get much farther. Read the tutorial.
