What does the program print on the monitor when it runs?
The variable contains: 123
To get the most out of these notes, copy the program to a text editor,
save it to a file called Example.java
, compile it, and run it.
See Chapter 7 on how to do this.
For a simulation of running the program, enter an integer
in the text box below and click on "Compile", then click on "Run".
(Note: if this does not work, your browser does not have JavaScript enabled.)
This is just a simulation (using JavaScript), so it is not exactly like a compiling and running a real Java program. Don't take it too seriously. Please do the real thing if you can.
Try entering something like "rats" in the declaration. Does the program compile successfully?
