How to get C like performance in Java

Understanding how Core Java really works can help you write simpler, faster applications. OverviewJava has many areas which can be slow. However for every problem there is a solution. Many solutions/hacks require working around Java's protections but if you need low level performance it is still possible. Java makes high level programming simpler and easier at the cost of making low level programm
