Answer 1

Try this website. It may have all the problems you are likely to encounter.

Good luck.

Answer 2

lets say this is ur code:
class test{
public static void main(String arg[]){
S.o.pln("hello..");
}
}

just make sure you save this file under test.java
if you are using the notepad, check if it is saved under test.java.txt, it is a common mistake.. the correct one is test.java

Answer 3

I guess, you gave different names for the file and class

It should be like

Example.java

public class Example {

.....

...
...
}

I guess you understand that the class name and file name must be same. Hope this will resolve.

Answer 4

give the full source code.might be issue with classpath.
