Csc211 LAB 1

On the C drive create a directory(folder) csc211.
Open up textpad
Before you type anything save the file as Welcome.java (The 'W' is uppercase) in the csc211 directory
Type in exactly as written the following program. (This is called the source code)
Next you want to compile it. On the toolbar in textpad select tools, then select compile java
If you do not see any error messages and you get the code back, now you want to run the program. From tool select Run Java Application
If the program compiled and ran correctly continue. If not, ask me or one of your classmates

Introduce the following errors, one at a time, to the above program. After you introduce the error, recompile the program. If the program compiles try running it. Make sure you Fix the previous error before you introduce a new one,

	(a)  Change public Welcome to public welcome

	
	(b)  Remove the first quotation mark in the string literal.

Add another println statement to the Welcome program so it prints out the message.

Next type in the program Calculator1. Before you do this create a new file in Textpad called Calculator1.java
Compile and run it.
If the program compiled and ran correctly continue. If not, ask me or one of your classmates

 	         operand2;
