Answer 1

It is possible that you are not in the same directory as the file when you are attempting to compile.
1. if you are typing javac Hello.java, make sure the prompt is in the same directory. For example, if you created the Hello.java file in C:\Test make sure the dos prompt is at C:\Test when you type javac Hello.java OR alternatively, if you didnt change the directory of the prmpt make sure you type javac C:\Test\Hello.java from the prompt.

2. Make sure the class specified in the file matches the actual file name. For example, public class hello{} must be in a file called hello.java, while public class Hello{} must be a file called Hello.java---notice that capitalization is NOT ignored.

Good luck.

Chech that u have used camel casing for the main class name and also that main class name is same as the file name Hello.java.
and u are writing the same in the command prompt while compiling.
