windows 7 x64 - How do I get my java program running even though it has no errors? What have I done wrong? How can I make the program run? -
in program supposed ask user whether or not order 1 pizza , if yes, must enter:
their last name (don't worry validating),
their choice of pizza type and
their choice of pizza size.
the choices veggie, cheese, pepperoni, , supreme. can small, medium, or large.
each person can order 1 pizza. things need validate initial response, types of pizza, , sizes. when compiled program had no errors, when tried run did show code. when "all did show code" mean on browser used showed see in notepad++. ran clicking "run" drop down button on notepad++. gave me options run in different browsers. tried running in mozilla , chrome same results (only showing source code, not running program). advice on how program working??

did compiled program before running? you must have jdk installed in pc
steps compile , run java program - 1 ) write java code using text editor , save file classname.java (in case, class name "pizzaorders" ).
2) open command prompt , navigate folder have saves previous file. (i.e pizzaorders.java).
3)run command javac pizzaorders.java.
4)run command java pizzaorders.
