Top Java Coders, Developers for Hire in Ukraine

Java is a highly typed programming language oriented on objects. Java apps are usually transformed into the bytecode, that’s why it can be displayed on any device using a virtual Java machine.The language was made by Sun Microsystems. The official release date is May 23, 1995. Often the disadvantages of the concept of a virtual machine include a decline in performance. A number of improvements have slightly increased the speed of execution of Java programs: the use of the technology of translating bytecode into machine code directly while the program is running (JIT-technology) with the ability to store class versions in the machine code; wide use of platform-oriented code (native-code) in standard libraries; hardware that provides faster processing of bytecode (for example, Jazelle technology supported by some ARM architecture processors).
