When calling method error .class expected

Question

First the method I'm calling.
public void ExeSqlStmt(String sqlStmt, String columnNames[], String connectString, String userName, String password,int numColumns)
This compiles clean. The code that calls the method is giving me fits with expecting .class, expecting ), can not resolve symble and unexpected type.
The offending line is near the bottom of the code.
Thanks,

Answer 1

In your call your referencing the array as colNames[] - it should be colNames (no []'s )
exeStmt.exeSqlStmt(sqlStmt, colNames, connectString, userName, password, 3);
