6. Experiment with this program. Add the following lines to the end of

your HelloWorld.java source file (i.e., immediately after the last println
statement):

// Create a new instance of the ErrorMsg class.
ErrorMsg myErrorMsg2 = new ErrorMsg ();
// Set the text item to some text String, and print its contents.
myErrorMsg2.setErrorMsg ("Some Text for #2");
tempMsg = myErrorMsg2.getErrorMsg ();
System.out.println (tempMsg);
// Print the text item in the original object.
tempMsg = myErrorMsg.getErrorMsg ();
System.out.println (tempMsg);

7. Save the program again. Compile and execute it by performing these state-

ments in the command window:

➔ javac HelloWorld.java

➔ java HelloWorld

Your DOS window should look like this:

C:>javac HelloWorld.java

C:>java HelloWorld
Hello World!
