Stages of Software Development Lifecycle using a waterfall approach In the waterfall approach, each stage of the project delivered is a set of tasks that have to be completed by a planned deadline. A common set of stages for a software development project are [1]: System requirements Software requirements Analysis Program design Coding Testing Operations (until the system reaches its end of life - EOL) In theory, after the requirements are gathered, and the system was designed, implementation has to satisfy the requirements and the design without the possibility of changing the agreements made during in previous phases. Each phase is a silo of work, which is disconnected from other silos . This can result in a situation of conflicting requirements being detected during the testing or deployment phase without a chance to discuss these requirements with their authors. Maintenance is a special type of stage because there are cases when it is unknown, how long the system will be...
When programming, sometimes you need to store a multi-line text in one String variable. So instead of having multiple variables of type String and then, joining all of them into one I recommend using Java feature called Text Blocks. Compared to a simple String variable, a text block has to start with a triple quotation mark. //regular String variables String greeting = "Welcome to Dastin Sandura's blogspot!"; String description = " I blog about the practical use of Java language. " For comparison, below is a String, initialized with a text block. //text block stored in String variable String multiLineGreeting = """ Welcome to Dastin Sandura's blogspot! I blog about the practical use of Java language."""; Both of the variables presented above are of type String, which means that by looking at a variable type you cannot tell if its value was set, by using the text block Java feature. However, the most critical difference betw...
