Java SE:

Java SE is the abbreviation of Java Platform, Standard Edition (also known as Java 2 Platform), used for development and Deploy Java applications on desktops, servers, and embedded devices and real-time environments. Java SE includes class libraries for developing Java Web services and provides the foundation for Java EE.
Java SE (Java Platform, Standard Edition, Java Standard Edition) is based on JDK and JRE.

Java EE:

Java EE, Java Platform Enterprise Edition (Java Platform Enterprise Edition), is a standard platform launched by Sun for enterprise-level applications and is used to develop B/S architecture software. It is mostly used for enterprise-level development, including web development and so on. Also called J2EE.

Enterprise Edition helps develop and deploy server-side Java applications that are portable, robust, scalable, and secure. Java EE is built on the basis of Java SE. It provides Web services, component models, management and communication APIs, and can be used to implement enterprise-class service-oriented architecture (SOA) and Web 2.0 applications.

Java EE is an architecture that leverages the Java2 platform to simplify complex issues related to the development, deployment, and management of enterprise solutions. The foundation of J2EE technology is the core Java platform or Java SE. Java EE not only consolidates many advantages of the standard version, such as the "write once, run anywhere" feature, the JDBC API for convenient database access, CORBA technology, and the ability to apply on the Internet security mode to protect data, etc., and also provides comprehensive support for EJB (EnterpriseJavaBeans), Java Servlets API, JSP (Java Server Pages) and XML technology. The ultimate goal is to become an architecture that enables enterprise developers to significantly reduce time to market.

The Java EE architecture provides a middle-tier integration framework to meet the needs of applications that require high availability, high reliability, and scalability without too much cost. By providing a unified development platform, J2EE reduces the cost and complexity of developing multi-tier applications, and at the same time provides strong support for the integration of existing applications, fully supports EJB, has good wizards to support packaging and deployment of applications, and adds directory support. Enhanced security mechanisms and improved performance.
