The core strengths of Java

Java is designed for consumer smart electronics, but smart home appliances are not as big as they were originally imagined. However, in the 90 's, the Internet has entered an explosive stage of development, and overnight, everyone is busy connecting their computers to the network. This time, met a big problem. People find that the Internet is connected to a variety of computers, such as IBM PCs, Macs, various servers and so on, not only the hardware CPU, operating system is different, the entire network environment is very complex. At this time, programmers want their programs to run in different machines, in different environments, which requires a system-neutral language (that is, cross-platform). The Java team suddenly found out that their use of small-scale languages also adapted to the environment of the Internet.

Cross-platform is the core advantage of the Java language, catching up with the development of the Internet, and with the development of the Internet, the establishment of a strong ecological system, has covered the IT industry's "first language", is the computer industry "English."

Although, there are many cross-platform languages, but have lost the opportunity to compete with Java's powerful ecosystem. Java will still become the mainstream language of programming languages in the coming decades.

Java virtual machines are the core of a Java implementation across platforms. In fact, there are a number of programming languages based on the Java Virtual Machine (JVM):
