The compiling error states that it is located where it says "& ansCorrect < 9", although I don't know how to fix it. Keep practicing in Lv2 to improve.") Ĭase ansCorrect = 0 & ansCorrect < 6: JOptionPane.showMessageDialog(null, "You scored" + ansCorrect + "out of 10. The specific part of code where the problem lies is as follows: public void answerValidation()įor(int i = 0 i =8 & ansCorrect =6 & ansCorrect < 7: JOptionPane.showMessageDialog(null, "You scored" + ansCorrect + "out of 10. The problem at hand is as stated in the question: I am receiving an "incompatible types" error when compiling my code and I can't seem to fix it regardless of any modification I do. I'd like to ask for assistance since I am relatively new to the program of Greenfoot. Hence our results show the larger the image dimensions used, the better the values.A new user here. The results of the paper are encouraging and efficient compared to other algorithms that performed the same work. Java itself is known for object-oriented programming. If you have previously had a basic java programming will be easier in understanding programming in greenfoot. The measures MSE, PSNR, NSCR, and UACI are using to measure the work efficiency in the encryption algorithm, and in measuring the efficiency of the hidden algorithm, use the measures SNR, PSNR, and MSE. One of them greenfoot applications that are easy to operate for beginners. Also used a fractional fourier transform to choose magnitude value as specific data to hide encoded image data. Greenfoot supports the Java Programming Language, so students learn standard object-oriented. This algorithm includes the LSB algorithm to determine the hidden bits and the zero-crossing K-means algorithm in selecting locations mining in a scattered manner so that hackers cannot easily retrieve the hidden data of any hacked person. An on-screen piano that you can really play. Finally, in the third phase, a new algorithm is suggested to hide the encrypted gray image at random locations within a speech file. These are just here for those of you curious to play without waiting for me to introduce things. English pig.' He was on the PA so I answered. Greenfoot scenarios shown in video: ants, asteroids, fatcat, little-crab, marbles, piano, wave, wombats (Note: At this stage you are not expected to do anything with these scenarios yet. The second phase generates hybrid keys by mixing a Zaslavsky and a 3D Hanon map that are used to encrypt the gray image values produced after the scramble. He was going to have one green foot and one blue foot for weeks. The first phase includes scrambling the values of the gray image depending on a series of keys that are generated using a quantum chaotic map. In this simulation insted of the piano playing music it plays star wars quotes. This paper proposes a working mechanism in three phases. CHAPTER 6: Making music: An on-screen piano. Your browser does not support the canvas tag. You can use your keyboard keys or the mouse to play. Basically you add bluejcore.jar and greenfoot.jar (found in your installation directory of Greenfoot) as your project libraries and create a properties file (details in the link) for Greenfoot. Introduction to Programming with Greenfoot: Object-Oriented Programming in Java with Games and Simulations. It isn't very good and 4a and b are skipped because there were not files provided. Information hiding techniques are constantly evolving due to the increased need for security and confidentiality. This link is about Greenfoot in Eclipse, but the steps also seem to work with IntelliJ.
