This quiz covers Programs 1-10 in Lab #1, but does not cover any of the Additional Exercises in that lab.
Important note: Quiz difficulty levels will increase with each of the first few quizzes. That is, this quiz is quite a bit less difficult than future quizzes in this class.
Question 1: Write a Java program which uses a while statement to compute and print out the sum of the integers from 123 to 789. That is, 123 + 124 + ... + 788 + 789.
Question 2: Write a Java program which reads in integers, stopping only when the same integer is entered in twice in a row. Print out the total number of integers read.
Question 3: Give the value that each of the following
expressions evaluates to (you should assume that all values are integers, and
all math is integer math).
3a) 2 * 3
3b) 2 * 3 + 4
3c) 2 + 3 * 4
3d) 9 / 3
3e) 10 / 3
3f) 11 % 3
3g) Math.abs(10) + Math.abs(-10)
3h) Math.abs(10 + -10)
