Interpretation is slower than native execution, and compilation at load java 7 certifications or runtime has an initial performance penalty for the compilation. Modern performant JVM implementations all use the compilation approach, so after the initial startup time the performance is equivalent to native code. When generics were added to Java 5.0, there was already a large framework of classes , so generics were chosen to be implemented using erasure to allow for migration compatibility and re-use of these existing classes.

  • Notable changes include language-level support for lambda expressions and default methods, the Project Nashorn JavaScript runtime, a new Date and Time API inspired by Joda Time, and the removal of PermGen.
  • They also help developers share information about their projects with other team members.
  • Java programmer certifications are designed to tell would-be employers whether or not you really know your stuff, and cracking the OCA Java SE 7 Programmer Certification is not an easy task.
