  1. Experiment content

(1) Search the Internet for information to understand the origin and development history of Java.

(2) Practice using common MS-DOS commands. Master the use of the following commands: dir, cd, javac, java, set, etc.

(3) Download and install jdk, and complete the environment setup.

(4) Develop a Java application separately and use the output method to output "East China Jiaotong University Welcome!"; set the string to be output as a variable and then output it; create a new class and set the string to be output to this Class attributes, use the main class method to create a new class object and implement string output.
