what is java2

The Java language is an object-oriented programming language. In December 1998, SUN released JDK1.2 and began to use the name "Java 2". At present, we rarely use the JDK1.1 version, so what we call Java refers to Java2.

In fact, Java2 is Java 1.2. Because the changes are relatively large compared to 1.1, it is called Java2.

However, currently we rarely use the JDK1.1 version, so the Java we refer to refers to Java2. That is the Java language.

Java has the characteristics of simplicity, object-oriented, distributed, robustness, security, platform independence and portability, multi-threading, and dynamics.

The release of the Java 2 platform is the most important milestone in the development of Java, marking the beginning of the popularization of Java applications.
