Could not find or load main class kel.java

Answer 1

If there is a main() method in kel.java and if it is successfully compile then

you can run it using following command.

java -classpath kel

in your case you are trying to run kel.java. That is wrong.

Answer 2

After compilation, just give class name, instead kel.java. Just mention kel.

Answer 3

After compilation, you can run by java kel. Simply remove the .class from you compiled file.

Answer 4

Even though your source file's name kel.java, your class' name is just kel

You have to start your program with

java -cp ... kel

You should not add any suffix to the class name.
