The difference between java and js

The difference between java and JavaScript is: runtime environment and object-oriented.

1, running environment: Java is a compilation language, and its code needs to run on a Java virtual machine (JVM). JavaScript is an explanatory language, and its code can run on any interpreter that supports JavaScript, such as a browser.

2. Object-oriented: Java is a completely object-oriented language, and all codes must be defined in classes. Although JavaScript is also an object-oriented language, it can operate on any object.

Enterprise applications of Java include various types of applications, such as e-commerce websites, enterprise resource planning (ERP) systems and customer relationship management (CRM) systems.

2. Mobile development: Java can also be used to develop Android applications. Android operating system is developed based on Java, so Java programmers can easily use Java language to develop Android applications, including various types of applications, such as social media applications, games, weather applications and so on.

3. Embedded system: Java can also be used to develop embedded systems. Embedded system is a special type of data processing system, which is usually used to control and manage machines, equipment or systems.
