HAVE READ:

• pp. [58-61,72-73,78-88]
• pp. [130-136]

KNOW:

• how to create a while loop.
• how to read a line of String input from the keyboard
• how to read values of primitive types from the keyboard when separated by spaces.
• use of Scanner hasNext() to determine if additional input is available

BE ABLE TO:

• Write programs with conditional control flow, based upon variable declarations

DAILY QUESTION:

• Write a program that reads a word from the keyboard and outputs that word five times, once per line.

Sample Exam Question:

Write a program that reads in two integers from the keyboard. Then if the first number is greater than the second number swap their values (hint: you will need a third variable to perform this action). Then output the numbers (one per line) such that the smaller number appears first, then the larger number second.

Go through all the steps in the design recipe in the development of your program.
