'cos' they are just comments.
When compiled, comments produce no executable code. Rather, comments are intended to let other developers know what is happening in a program.
That means to load a computer program into a computer's memory, and have the computer carry out the instructions in the program.
The program that runs on the client computer is the client program. Web-browser is a prominent example for client program.
Java is a semi compiled programming language. This means that when the program is written it is compiled into BinCode which is machine independent. When it arrives at your computer is is then compiled using the components of the Java runtime into code which can be executed on your computer (usually displayed in your browser). The Java runtime is the collection of library files compiler and virtual machine to make this possible.
It is normally interpreted by another computer program. However subsets of the language can be compiled.
The program compiled itself to give the correct result.
As far as I know, interpreted software does not run compiled software at all.
Compile time is when the compiler translates your source code into computer language. Run time is when the actual program runs.
That refers to the program that runs the compiled Java program.
In Computer Science, source code is generally computer instructions written in a form that is able to be read by a human. Source code is usually text and can even include comments about a computer program.
Java is a computer programming language. Java programs can be interpreted (the computer compiles and runs the program as the code is executed) or it can be pre-compiled into bytecode (the computer doesn't have to compile it as soon as it is run, so time is saved.)
The comments are there to (a) aid in debugging the program, (b) help the programmer layout the program in logical steps and (c) show anyone else looking at the code to see what each section of the code actually does.
