The program uses a random number generator to simulate our case. Random r = new Random(); boolean male = r.nextBoolean(); TheRandomclass is used to produce random numbers. ThenextBooleanmethod returns randomly a boolean value. if (male == true) { ...
Reverse a String in Java Java Object-Oriented Programming (OOP) OOP is a programming paradigmthat assumes centrality in Java because it allows for codes that are modular, reusable, maintainable, or easy to develop. The most characteristic features that it uses include classes and objects, encapsula...
