Question

java

Write a program using console dialog (see InputTest.java and Retirement.java) to read two or more resistance values and calculate the total resistance if the resistors are in series and if the resistors are in parallel.

Modify the program to use command line arguments for the resistance values.

Modify the program again to use JOptionPane

Create a bin directory on your computer and add it to your path. Download the utility dsize.zip and unpack it into the bin directory. Open a command window, change (cd) to some folder that has sub-folders, and enter the command:

Capture a screen image of the resulting output and embed the image in your submission.

Download hilite.zip and get the source-highlighting program to work. Note: copy the un-zipped files in Src-Highlite.zip to your C:Program Files directory. Keep the same directory structure.

You should submit an index.html document summarizing your work and reporting validation tests. You should also submit source files and other files helpful in reconstructing or verifying your work.

Explanation / Answer

NOTE : Create 3 classes. 1. Main.java ; 2. Resistance.java ; 3. ClosingFrame.java. Copy each of the elow respective code in there respective files. Keep all the three Java files at same location.

For excercise 4. You need to install the file in your PC and run it. Pleas download and run the file as instructed.

For excercise 5. Youjust need to extract the files in your C drive>> Program Files.
