    3. From the Save as type combo box, choose Text Documents (All Files).

    1. Open "comand prompot" window. You can first start then run type cmd and then this console window is open
    2. The command prompt shows your current directory, show your current directory your home directory for Windows 7. To compile your source file then generate a byte code (.class file). For example, if your source directory is Newfolder on the C drive, type the following command at the prompt and press Enter:
    3. cd C:\Newfolder
