What will happen if i pass query to executeUpdate of prepared statment

[Yogesh Gandhi]

Connection con=DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:xe","system","oracle");  
  
PreparedStatement stmt=con.prepareStatement(query1);  
stmt.setInt(1,101);//1 specifies the first parameter in the query  
stmt.setString(2,"Ratan");  
  
int i=stmt.executeUpdate();  

What will happen if i use stmt.executeUpdate(query2); in the above code?

Will it execute query1, or query2? or will it complain or what will be the behavior.

I learn that we cannot use executeUpdate with parameters on PreparedStatement. It is only meant for Statement object.
But what happens if I do?

The documentation tells you what it does:

Throws:
SQLException - if a database access error occurs, this method is called on a closed Statement, the given SQL statement produces a ResultSet object, the method is called on a PreparedStatement or CallableStatement
