[Crazy Java handouts-Reading Notes] A Brief History of 1.1Java, handout 1.1 java

At the end of 1990, James Gosling led the Green Program to prepare a general control system. Using an embedded platform, James Gosling had limited system resources and C ++ was not suitable, because C ++ is too complex, it lacks the garbage collection system, portability, distributed and multi-thread functions. Gosling decided to create a brand new language Oak.

In the summer of 1992, the Green plan had been completed. In November of the same year, the Green Plan was converted into "FirstPerson". Several successive transactions on the set-top box failed, and the Green Plan was almost aborted.

In the summer of 1994, the Internet and browsers bring the gospel to Oak, WebRunner, a Java-language browser. Because the Oak trademark has been registered by someone else, it is renamed Java.
