Problem 1
Create a complete Java program in a class named Bday that declares four variables and assigns appropriate values to them.
your birthday month (1-12)
your birthday day (1-31)
the birthday month of another student sitting near you today (1-12)
the birthday day of that same student near you (1-31)
Ask your neighbor for their name and for the proper numbers to store in the variables for his/her birthday. Then produce output in this format using your four variables:
My birthday is 9/19, and Suzy's is 6/14.
Problem 2 : Syntax errors(10)
The following program contains 9 mistakes! What are they? Copy and paste the following code into Jgrasp/Eclipse and correct the various mistakes.
public class Oops {
public static void main(String[] args) {
int x;
System.out.println("x is" x);
int x = 15.2; // set x to 15.2
System.out.println("x is now + x");
inty; // set y to 1 more than x
y = int x + 1;
System.out.println("x and y are " + x + and + y);
}
}
Problem 3:
Write a for loop that produces the song Bottles of Beer on the Wall:
10 bottles of beer on the wall, 10 bottles of beer
Take one down, pass it around, 9 bottles of beer on the wall
9 bottles of beer on the wall, 9 bottles of beer
Take one down, pass it around, 8 bottles of beer on the wall
... (output continues in the same pattern) ...
1 bottles of beer on the wall, 1 bottles of beer
Take one down, pass it around, 0 bottles of beer on the wall
Problem 4:
Write a complete Java program that produces this sequence of numbers using a for loop:
8
11
14
17
20
23
Problem 5: Printing a design
Write a program to produce the following output using nested for loops. Use a table to help you figure out the patterns of character on each line.
Test your loop expressions in Practice-1t! using the checkmark icon above. Use your expressions in the loop tests of the inner loops of your code.
Problem 6:
Consider the following method for convening milliseconds into days:
// converts milliseconds to days
public static double toDays (double millis) {
return millis / 1000.0 / 60.0 / 60.0 / 24.0;
Write a similar method named area that takes as a parameter the radius of a circle and that returns the area of the circle. For example. the call area (2.0 ) should return 12. 566370614359172. Recall that area can be computed as it times the radius squared and that Java has a constant called Math . PI.
Problem 7:
Write a method named pay that accepts two parameters: a real number for a TA's salary. and an integer for the number of hours the TA worked this week. The method should return how much money to pay the TA. For example. the call pay (5. 50, 6) should return 33.0.
The TA should receive *overtime pay of 1.1/2 normal salary for any hours above 8. For example. the call pay (4.00, 11) should return (4.00*8) + (6.00*3) or 50.0.
