Compiling two java files at a time?

Why is a just-in -time compiler useful for executing Java programs?

I'm not sure if it's "useful" as much as it is the fact of it being how the Java compiler works. However, there's a GCC frontend for compiling Java to native machine code rather than bytecode.

How do you compiling a source code in java?

The javac command is used to invoke Java's compiler and compile a Java source file. A typical invocation of the javac command would look like below: javac [options] [source files] Both the [options] and the [source files] are optional parts of the command, and both allow multiple entries. The following are both legal javac commands: javac -help javac ClassName.java OneMoreClassName.java The first invocation doesn't compile any files, but prints a summary of valid options. The second invocation passes the compiler two .java files to compile (ClassName.java and OneMoreClassName.java). Whenever you specify multiple options and/or files they should be separated by spaces. This command would create the .class files that would be require to run the java progam.

Compiling Java ProgramsThe javac command is used to invoke Java's compiler and compile a Java source file.A typical invocation of the javac command would look like below:javac [options] [source files]Both the [options] and the [source files] are optional parts of the command, and both allow multiple entries.

Whenever you specify multiple options and/or files they should be separated by spaces.This command would create the .class files that would be require to run the java progam.Compiling with -dBy default, the compiler puts a .class file in the same directory as the .java source file. This is fine for very small projects, but once you're working on a project of any size at all, you'll want to keep your .java files separated from your .class files. The -d option lets you tell the compiler in which directory to put the .class files it generates (d is for destination).Lets take a look at two example commands:javac -d classes source/MyTestClass.javajavac -d ../classes com/scjp/test/MyTestClass.javaExample 1 - Compile file named "MyTestClass.java" that is present inside the "source" sub-directory of the current directory and put the .class file in the "classes" sub-directory of the current directoryExample 2 - Compile the file named "MyTestClass.java" that is present in the following directory hierarchy "com/scjp/test/" from the current directory and put the .class file in the folder "classes" that is present one level above the current directoryOne thing you must know about the -d option is that if the destination directory you specify doesn't exist, you'll get a compiler error. If, in the previous example, the classes directory did NOT exist, the compiler would say something like:java:5: error while writing MyTestClass: classes/ MyTestClass.class (No such file or directory)

What is the statement which causes header files to be merged with the source files statements before compiling takes place?

#include #include "filename"The difference between these two is that, in the first example, the compiler will look in "standard" places for the included file, while, in the second example, the compiler will look in "user specified" places for the included file.
