Midterm Study Exercises:
Here is a study fill in the blank sheet of the basic Java syntax you need to know
Write the following programs in both Alice and Java:
1. Ask a user for 2 numbers. Put both numbers into variables. Switch the values in the variables. Print out the first variable value and then the second one.
2. Ask a user for one number, and then add4 to it 5 times, telling the user the new value each time. To accomplish this: Write and use a function add4 to take a given number parameter and add 4 to it.
3. All of your homework exercises are also excellent study
exercises, including the CodeLab exercises.
Simpler programs:
4. Ask the user for a number and print the absolute value of the
number using Math.abs. (This ensures you know how to use scanner, and
Math.abs.)
5. Write a program that sets 2 variables and then prints the highest
of the two variables.
6. Fill in the main method for this program:
public class myTest
{
public static void main()
{
String mood = "happy";
int age = 3;
// call the method printMood passing
it mood and age
// change the mood to sad and x to 2
// call the method printMood
passing it mood and age
}
public static void printMood (String myMood, int
myAge)
{
System.out.println("I am " + myAge + "years old and I am " + myMood);
}
}
