    Default Connect class with code?...?

    I am a beginner to java, and as I was reading my textbook I got confused....so I'm here.

    It says you can create your own classes which define methods, then you can write a separate code which invokes that new class you created and creates objects with reference to the new class. My question is, in my book they are shown in two files...how do you connect the two so the code knows where the class info is? Make sense?

    If I've understood your question, its quite simple; All that needs to be done is keep
    the source/class files in the same directory and it will be fine.

    ie.
    Take this directory:
    C:\Users\YourName\HelloWorld

    Then inside HelloWorld have two .java files
    MyFirstClass.java and MyFirstClassTest.java
    Then when you compile (via command line?)
    you'd type:
    C:\Users\YourName\HelloWorld\javac MyFirstClass.java
    C:\Users\YourName\HelloWorld\javac MyFirstClassTest.java

    Now the class files will have been created and will be in the same current directory and aslong as this is the case, they will find each other.
    When you run MyFirstClassTest with
    C:\Users\YourName\HelloWorld\java MyFirstClassTest
    It will run fine.

    When you get more into Java you can start reading about Packages.
