My programme is this:
class HelloWorld {
// main: generate some simple output
public static void main(String[] args) {
System.out.println("Hello, world.");
}
}
This is what appears:
HelloWorld.java:2: cannot find symbol
symbol : class string
location: class HelloWorld
public static void main(string[] args) {

You write "public static void main(String[] args)"
The compiler reports an error in "public static void main(string[] args)"
Since Java-coding is case-dependent, it's an understandable message. The name of the class is String, not string.
By the way, why add this parameter (a String array of arguments) if you don't use it? That's what I call bad programming. It's sufficient to write public static void main().

The first hit on google about the SELECT is http://www.w3schools.com/sql/sql_select.asp
SELECT * FROM table_name
Years later I'm still fixing that one in far too many systems.

Here's a longer discussion why it's rarely good.

It's fine for ad hoc things but in production code is usually the sign of a beginner SQL programmer or laziness.
