When I try to run compiled .class java program with this command
java main.class
I get this error
Error: Could not find or load main class main.class
When I compile the program with
javac main.java
It compiles nicely with no errors and gives me a .class file
What am I doing wrong?
I tried editing system variables to no avail.
When you run the java command it expects the fully qualified name of a class that has a main method (application entry point) not a class file name.
So it should be
java Main
Where Main is the fully qualified name of a class of the same name, residing in the default package in this case.
You may want to take a look at the documentation of the java command.
You may simply write this to run the program:-
java main
Remove the .class
let me explain you from very basic
.class files are created when you compile a .java file
javac is a command to compile a java code i.e. .java file
whereas java requires precompiled files. that can me a "NAME" of a class which has main method in it or it can be an entire .jar file.
so in your case the command which you are looking for is "java main".
java main. You don't want the.class.
