Java is a class-based, general-purpose object-oriented programming language designed to have fewer implementation requirements. Java is a computing platform for application development that is quick, safe, and dependable. As a result, it's widely used in data centers, game consoles, cell phones, laptops, scientific supercomputers, and other places to create Java applications.
With other more popular features like ARM blocks and String in Switch, the Java API gives outstanding support for random numbers with the java.util.Random class, Math.random() utility method, and the recently added ThreadLocalRandom class in Java 7. This random() method appears to be the best way to generate random numbers in Java; it only produces random doubles, but you can also use Random to generate floating-point numbers and pseudo-random integers.
The Java Platform is a collection of programs that make it easier for programmers to design and operate Java applications. It consists of a compiler, an execution engine, and a library collection. It's a mix of computer software and technical standards.
