CODE EXAMPLE FOR JAVA

error: could not find or load main class main caused by: java.lang.classnotfoundexception: main

//well, that means that ur main method doesn't exist, or your main method is out of your class.
//so, keep focusing in bracing part.
//main method should be like this:
Class main{
	public static void main(String[] args) {
	//ur code
	}
}


//hopefully this can help u :D
