just-in-time compilation(The compilation that converts Microsoft intermediate language (MSIL) into machine code at the point when the code is required at run time)
just-in-time compiler(A compiler takes the Java bytecode (which is machine-independent) and compiles it on demand into native code for the target machine, giving faster execution. Since JIT compilers operate on the client machine, they preserve the platform-independence of the compiled Java program)
just-in-time debugging(A technique that catches faults that occur while the program is running outside the development environment. You must set this option in the development environment before executing your program)
