    Question Question about File renameTo() method : Abnormal output

    public static void main(String[] args) throws Exception
    {
    File fl1 = new File("D:/Education/Java/Test1");
    File fl2 = new File("D:/Education/Java/Test2");
    fl1.renameTo(fl2);
    p("New File Name is : "+ fl1.getName());
    }

    For the above code snippet O/P is
    run:
    New File Name is : Test1
    BUILD SUCCESSFUL (total time: 2 seconds)

    My question is :
    At my system although the Test1 gets renamed as Test2 after compilation but still fl1.getName() returns the old name Test1. Why so?

    Read the caveats for this method in the Method Detail section of the File api.
