1/Write a TeachArithmeticFrame class that teaches children arithmetic. The frame uses a JLabel for a problem and a JTextField for the user answer. When the user presses the Enter key (while the JTextField object is active) or clicks the OK button, display a message stating whether the user’s answer is correct. When the Next button is clicked, display a new problem. The numbers are limited to two digits. Consider using a larger font for the JLabel and JTextField text. You can change the color of text by calling the setForeground method, for example. questionLbl.setForeground(Color.RED); 2/Extend the TeachArithmeticFrame class so that …

Hello. At work, I have to count about 5k in a day for products. When someone takes out or puts in products for example 450 I have to recount again. So I want to create a system that when someone puts some kind of product on the shelf they would enter the quantity they are putting on the stock. For example, TOM puts 150 pcs of -product1- in stock. Then Bill will take 50 pcs of the same product1. So the system would do the calculation: 150-50 = 100 pcs left in stock. When TOM will put again 110 pcs …

**Task** Your task is to write a program that will draw graphs and output them as coloured image in the .ppm file format and display them using a suitable external image viewer (IrfanView). The program will use code generated sine waves, and harmonics of these, to calculate and display the harmonic components of a square wave. All sine wave harmonic should be displayed, each in a different colour – and the square wave that results from summing all the sine waves should also be displayed. The resultant waveforms should be output as a single file in the .ppm format. Initially, …

Before anyone files a bug report, we are no longer pretty printing (using javascript to add line numbers & color coding) code snippets when on mobile browsers for performance reasons. It's not that it was particularly non-performant on mobile.
