Re: [Java] NoClassDefFoundError exception

 

Hello
This message tells you that there is no class named first.class.

ex:
1- source code
class First  //  no public and capital letter F
{

system.out.println("Hello world");

}

2- save source code in file named first.java // note small letter f
3- compile it
4- output of compilation will be First.class // capital F as source code not small f as file name

5- so , you must use capital Letter "java First" because there is no file named first.class with small f

also, if you want make a class pulbic you must name the file as source code with capital F
also, only one class in the same file can be made public
