One of the main challenges of being a programmer or software engineer is constant learning. Yes, that's true. As a programmer or developer, we always need to learn new things, sometimes every year. Thanks to C, Java, Linux, and SQL, we still have some ground, but the way these technologies are used changes every year. For example, we have a new JDK 12 release this year, even though many Java developers are still learning Java 8. We also have a Spring Framework 5.0 release last year, combined with Spring Security 5.0 and Spring Boot 2.0 version, which many of us need to learn in 2020.

Eclipse - Access restriction: The type BASE64Decoder is not accessible due to restriction Error [Solved[
Hello guys, if you have been using Eclipse for Java development then you might have seen this dreaded "Access restriction: The type BASE64Decoder is not accessible due to restriction Error" before. This error comes when you are trying to encode String into Base64 using BASE64Decoder in Eclipse because the class BASE64Decoder is not part of JDK's public API, it comes from sun.misc package which is non-public. Though this class is present in JDK and JRE and allows you to encode and decode String into base 64, any access to this class from Eclipse flags as an error in Eclipse IDE. If you compile and run the same program from the command line or Netbeans you will not get this error.

One of such frequently asked SQL question is the real difference between table scan, index scan, an index seek? which one is faster and why? How does the database chooses which scan or seek to use? and How you can optimize the performance of your SQL SELECT queries by using this knowledge. In general, there are only two ways in which your query engine retrieves the data, using a table scan or by using an index.
