Open command window "cmd" from Windows prompt.
Type in "javac" in the window. The command should execute giving full usage
of javac and its options. If you get an error message saying that "Javac is not a recognized as an internal or external command", than the Path has not been set.

Why path and class-path in java?
1))What is the difference between "path" and "classpath"? Ans:: We keep all "executable files"(like .exe files) and "batch files"(like .bat) in path variable. And we keep all jar files and class files in classpath variables. So path is set according to the .exe files & .bat files And classpath is set according to the .jar files & .class files. Operating system tries to find .exe and .bat files in path and JVM tries to find all classes in classpath.
How do you set path in java?
1. install JdK 2. include JDK_HOME/bin in your PATH environment variable
What is classpath and path in java?
if you are using the IDE then there is no need to set class path, ant you are using Command prompt to run the java program then you need to set the class path where the class (which is going to be used in your program) is actually located,use the following command:set calsspath=%classpath%;actual_path_of the class;we cancall more than two class by using this command by using separator (,)

Make sure the environmental variables "classpath" and "path" are properly set. Also check if all requisite JARS are present in the projects build path. In case you are getting this during File input/output - check if the file is present in the appropriate location.

How do you set java environment variables?
You need to set The CLASSPATH variable which is an argument set on the command-line that tells the Java Virtual Machine where to look for user-defined classes and packages in Java programs. Syntax is java -classpath "path to the packages". Set the PATH variable if you want to be able to conveniently run the Java 2 SDK executables (javac.exe, java.exe, javadoc.exe, etc.) from any directory without having to type the full path of the command. To set the PATH permanently, add the full path of the j2sdk1.4.2_version\bin directory to the PATH variable. -sravyaa

Make sure you typed the file's name correctly and that you are in the correct directory, or type the file's full path. Try typing "dir" or "ls" and check if the file is actually there.For example, here's what it would look like if you had Test.java in C:\JavaProgramsC:\JavaPrograms>javac Test.javaAnd then to run the compiled program you do thisC:\JavaPrograms>java Test** Also, you have to set the path of the compiler.

Java is both compiled and interpreted language meaning?
Instead of compiling to machine language, the Java compiler compiles for a "ficticious processor". A program called the Java Virtual Machine then interprets this on every machine. Note that Java is NOT an interpreted language. It is solely a compiled language. Java source code is always run through a compiler (typically 'javac') to be turned into bytecode. This is identical behavior as any other compiled language. The confusion is that Java bytecode is usually run on a Java Virtual Machine, which itself may both act as an interpreter and a compiler for the native instruction set the JVM runs on. However, the Java language itself is NOT dependent on how this bytecode is run - in fact, it is possible (and has been done) to build a hardware machine that runs Java bytecode directly.
