The first simple explanation of the Java cross-platform features is equivalent to saying that a Java program can run on different operating system platforms (the platform here is simply viewed as an operating system platform). Let's use some examples to illustrate its benefits.We first understand some basic knowledge, the computer is composed of hardware and software, software is divided into system softwar
