The Sun Certified Java Developer (SCJD) certification was a certification program offered by Sun Microsystems, which is now owned by Oracle Corporation. The SCJD certification was designed for Java developers who have a solid understanding of Java programming and who are interested in developing network-based Java applications.
The SCJD certification program was retired in 2010, and there is no direct replacement for it. However, the Java programming language and platform have continued to evolve, and there are other Java certifications available from Oracle, such as the Oracle Certified Professional Java Developer (OCPJD) certification. This certification focuses on the development of enterprise applications using Java technologies such as JPA, EJB, and JAX-WS.
