In this program, we will create a simple calculator to perform addition, subtraction, multiplication, and division operations using a switch case. Program/Source Code: The source code tocreate a simple calculator using the switch caseis given below. The given program is compiled and executed succe...
Save the TradeEvent.java file and close the code window. And that's all there is to creating a JavaBean (at least, in this case). The next step is to tell your application that the JavaBean should be used as an event type. Configure the TradeEvent Event Type In this section, you'll...

Then, switch...case statement is used for checking the operator entered by user. If user enters + then, statements for case: '+' is executed and program is terminated. If user enters - then, statements for case: '-' is executed and program is terminated. This program works similarly for...
The Java Object Mapper is a simple, light-weight framework used to map POJOs to the Aerospike database. Using simple annotations or a configuration YAML file to describe how to map the data to Aerospike, the project takes the tedium out of mapping the da
It can be very cumbersome, error prone, and time consuming to converse with a computer using only zeros and ones. Numerical machine code (computer code using only zeros and ones) does exist but is rarely used by programmers. For that reason most people program using a “higher-level”...
In addition to asserting the correct code, Lizard may choose not to deal with some advanced or complicated language features: C/C++ digraphs and trigraphs are not recognized. C/C++ preprocessing or macro expansion is not performed. For example, using macro instead of parentheses (or partial stat...
Although it's hard to visualize what color XOR mode will pick, there is one important special case. Let's say that there are only two colors: a background color (the XOR color) and a foreground color (the painting color). Each pixel must be in one color or the other. Painting “...
