1Z0-811 - Java Foundations exam

Hello,

This practice tests will help you to check your basic Java knowledge before passing official 1Z0-811 exam. Every example question here was checked, tested and explained by me. You can be sure about the answers, as each piece of code has been written in IDE and tested.

Passing this exam will give you first official Java certificate - Java Certified Foundations Associate. This exam is also Java version independent so it will be valid forever.

Please find additional information about this exam straight from the Oracle website:
