18. Save this class, and then compile it in the command window:
➔
javac ErrorMsg.java
19. Add the
bolded
lines of code to the end of the
HelloWorld
class so that it
looks like this:
// Call the new variation on getErrorMsg.
tempMsg = myErrorMsg.getErrorMsg ('U');
System.out.println (tempMsg);
// Print the public variables after performing this overloaded call.
System.out.println ("msgSize " + myErrorMsg.msgSize);
System.out.println ("interface " + myErrorMsg.interfaceInUse);
System.out.println ("counter " + myErrorMsg.getCounter ());
// Print the localCounter variable.
System.out.println
("localCounter " + myErrorMsg.getLocalCounter ());
20. Save the source file, then recompile and run the modified program in the
command window:
➔ javac HelloWorld.java
➔ java HelloWorld
