This article mainly introduces the java development of .java files and .class file example analysis, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let Xiaobian take you to understand.

Generation process

Create a local text file with the .java suffix and write down the statements you want to execute, as shown in the following figure:

Use the javac command to compile (note: if you download JDK), compile as follows:

Step 1: enter the bin directory of JDK, enter cmd in the file directory path, and enter the dos interface

Step 2: execute the javac + Java file path, as shown in the following figure

Finally, you get the class file, as shown in the figure:

Note: if you want to execute the class file, go directly to the dos interface under the current directory and execute Java Test to see the output of the program.

Conclusion: through the operation of the whole process, I believe you have basically understood the connections and differences between them, which can be summarized as follows:

You can think of the Java file as just a text file, which is a program written in Java, or a block of code for a task.

Class file is essentially a binary file, it is generally generated by a .java file through the javac command (the tool provided by jdk itself), and this file can be loaded (class load) by jvm (java virtual machine), and then interpreted and executed into java, that is, to run your program.

Thank you for reading this article carefully. I hope the article "sample analysis of .java files and .class files in java development" shared by the editor will be helpful to you. At the same time, I also hope you will support us and pay attention to the industry information channel. More related knowledge is waiting for you to learn!
