Assume that the first value read specifies the number of values to input from the user. The factorial of a positive integer n written n! Write an application that evaluates the factorials of the integers from 1 to 5. Display the results in tabular format in a JTextArea that is displayed on a message dialog.

What difficulty might prevent you from calculating the factorial of 20?

Use a for loop to vary the interest rate. Add scrolling functionality to the JTextArea so you can scroll through all the output. Use for loops to generate the patterns. A statement of the form System.

There should be no other output statements in the program. The last two patterns require that each line begin with an appropriate number of blanks. Write an applet that reads five numbers each between 1 and For each number read, your program should draw a line containing that number of adjacent asterisks.

Method fillRect of class Graphics requires the same arguments as method drawRect. Multiply each number entered by the user by 10 to determine the width of the rectangle.

Write an application that reads a series of pairs of numbers as follows: Your program should use a switch structure to help determine the retail price for each product. Your program should calculate and display the total retail value of corn stock market prices products sold last week.

Use a TextField to obtain the product number from the user.

Use a sentinel-controlled loop to determine when the program should stop looping and display the final results. Treat all monetary amounts as integral numbers of pennies. Then "break" the result into its dollar portion and cents portion by using the division and modulus operations, respectively.

What does each of the following statements print? Are the parentheses necessary in each case? If you are not familiar with these number sprint stock market today yahoo finance, read Appendix E, first.

Place the results in a JTextArea with scrolling functionality. Display the JTextArea in a message dialog. Print a table that shows the value of p approximated by one term of this series, by two terms, by three terms, etc.

These three sides must satisfy the relationship that the sum of the squares of two of the sides is equal to the square of the hypotenuse. Write an application to find all Pythagorean triples for side1side2 and the hypotenuse all no larger than Use forex hero apk triple-nested for loop that tries all possibilities. This is an example of joptionpane character input force" computing.

You will learn in more advanced computer science courses that there are large numbers of interesting problems for which there is no known algorithmic approach other than using sheer brute force.

These laws state that the expression! Maximize your use of repetition with nested for structures and minimize the number of output statements. Your program should then display a diamond of the appropriate size.

Actually, break statements and continue statements can always be replaced by structured statements, although doing so can be awkward. Describe in general how you would remove any break statement from a loop in a program and replace that statement with some structured equivalent. The break statement leaves a loop from within the body of the loop.

The other way to leave is by failing the loop-continuation test. Use the technique you developed here to remove the continue statement from the program of Fig.

A separate switch structure should be used to print the remainder of each verse. Included below are answers to approximately half the of the exercises in the Cyber Classroom.
