Java Programming - Write a GUI program which incorporates a try-catch block to error check your input for integers and alphabetic characters other than Y or N. Your program must include two interactions. Each interaction will ask the user at least two questions, both of which require a yes/no response (Y or N). The program flow will depend on both user responses. Your program must include at minim...

Java Programming - Write a complete interactive Java GUI program(for example: javax.swing.JOptionPane;) NOT A APPLET that requests two numbers from the user. The first number is the row dimension and the second number is the column dimension. Print to the user a rectangle of stars based on the input. The program must do the following: 1. Print the rectangle of stars. 2. Error check for bad inp...

PERL Programming - 1. Physicists tell us that the lowest possible temperature is absolute zero. Absolute zero is -459.69 degrees Fahrenheit. a. Accept inputs from the user: a beginning temperature, an ending temperature, and an increment value (all Fahrenheit). b. Check for bad input: a temperature less than absolute zero and an ending temperature less than a beginning temperature. The pro...

PERL Programming - Write a program called tripper.cgi that will ask the user the number of miles he has driven and the amount of gas he used. In the tripper script, write a subroutine called mileage that will calculate and return the user’s mileage (miles per gallon). The number of miles driven and the amount of gas used will be passed as arguments. All variables should be my variables. Print th...

Java Programming - You have already written the code for the four loop problems which you will now combine into one program with four distinct methods. For this assignment you will write methods, two value returning methods and two void methods. You may choose which of the four problems are coded into which method. Each method must represent one of the 4 distinct loop problems. The methods must i...
