COSC 236
Lab 2*

1.   Write a complete Java program that produces the following output (use System.out.println() to print each line to the screen):

What is the difference between

a ‘ and a “?  Or between a ” and a \”?

One is what we see when we’re typing our program.

The other is what appears on the “console.”

2. Write a complete Java program that produces the following output (use System.out.println() to print each line to the screen):

A “quoted” String is

‘much’ better if you learn

the rules of “escape sequences.”

Also, “” represents an empty String.

Don’t forget: use \” instead of ” !

” is not the same as ”

3. Write a program that stores the integers 62 and 99 in variables, and stores their sum in a variable called total. Print out the total to the screen.

4. Write a program that declares the following:

·         a String variable named name

·         an int variable named age

·         a double variable named annualPay

Store your age, name, and desired annual income as literals in these variables. The program should display these values on the screen in a manner similar to the following:

My name is Joe Smith, my age is 26 and

I hope to earn $100000.0 per year.

5. Write a program that has the following String variables: firstName, middleName, and lastName. Initialize these with your first, middle, and last names. The program should also have the following char variables: firstInitial, middleInitial, and lastInitital. Store your first, middle, and last initials in these variables. The program should display the contents of these variables on the screen.
