Compiler bug?

So, when I have to initialize the variable in the constructor, and I use Craig's method, it won't compile. For example when I write it like this : "mCreationDate = creationDate;" I get this error: " symbol: variable author
location: class Treet
./com/teamtreehouse/Treet.java:13: error: cannot find symbol
mDescription = description;
^ " But when i use "this" to refer to the current object, like this: "this.mCreationDate = mCreationDate;" my code works just great.

Why?

Hello, @Roland Williams! Thank you for the fast answer. Lately, I got it, it was my mistake. When I was declaring the parameters of the constructor i have declared it wrong, something like the following example:

// bla-bla-bla main class stuff
private String mExample;
public Method (String mExample) {  // instead of public Method (String example)
mExample = example; 
}

So the problem is you named the argument for the constructor mExample as well. When you try to set mExample to example below, there is no example variable.

private String mExample;
public method (String **example**){
mExample = example;
}
