public void setHoursWorked        hoursWorked   hours      You haven t defined hours inside that method  hours is not passed in as a parameter  it s not declared as a variable  and it s not being used as a class member  so you get that error

If you look at the scope of the variable  hoursWorked  you will see that it is a member of the class  declared as private int   The two variables you are having trouble with are passed as parameters to the constructor   The error message is because  hours  is out of scope in the setter

I ve noticed bizarre behavior with Eclipse version 4 2 1 delivering me this error   String cannot be resolved to a variable   With this Java code   if  true      String my variable    somevalue       System out println  foobar      You would think this code is very straight forward  the conditional is true  we set my variable to somevalue   And it should print foobar   Right    Wrong  you get the above mentioned compile time error   Eclipse is trying to prevent you from making a mistake by assuming that both statements are within the if statement   If you put braces around the conditional block like this   if  true       String my variable    somevalue         System out println  foobar      Then it compiles and runs fine   Apparently poorly bracketed conditionals are fair game for generating compile time errors now
