try{
Connection conn=DriverManager.getConnection("jdbc:microsoft:sqlserver://CE800:1181;UseDatabaseName=supermarket;user=sa;Password=");
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("select * from customers");
while(rs.next()){
System.out.println(rs.getString("username"));
conn.close();
}catch(Exception e){
e.printStackTrace();
return;

Answer 1

Your code seems ok, you probably end up in another Database than you expect.
Not sure about the the UseDatabaseName=supermarket clause in your connection string.
You can confirm that get a connection to another database by changing your query to:
SELECT * FROM supermarket.dbo.customers
if this works you probably get a connection to master and should look closer at the UseDatabaseName=supermarket clause.
You did try to run the query in the Query Analyzer i take it?
