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.

Đang xem: Java cannot be resolved to a variable

The error message is because “hours” is out of scope in the setter.

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.

I”ve noticed bizarre behavior with Eclipse version 4.2.1 delivering me this error:

String cannot be resolved to a variableWith 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.
