Java Compilers

ALSO CALLED: Java JIT Compiler, Java Just-in-Time Compiler, Just-in-Time Java Compiler
DEFINITION: In the Java programming language and environment, a just-in-time (JIT) compiler is a program that turns Java bytecode (a program that contains instructions that must be interpreted) into instructions that can be sent directly to the processor. After you've written a Java program, the source language statements are compiled by the Java compiler into bytecode rather than into code that contains instructions  …

JAVA COMPILERS DEFINITION (continued): …  that match a particular hardware platform's processor (for example, an Intel Pentium microprocessor or an IBM System/390 processor). The bytecode is platform-independent code that can be sent to any platform and run on that platform. In the past, most programs written in any language have had to be recompiled, and sometimes, rewritten for each computer platform. One of the biggest advantages of Java is that you only have to write and compile a program once. The Java on any platform will interpret the compiled bytecode into instructions understandable by the particular processor. However, …
