Java How can I create a MySQL table with specific column names and types using Java?

[Franco]

need help with some coding


public void createTable(String tableName, String[] columnNames, String[] columnType, String[] Keys) throws SQLException {

try {
stmt = conn.createStatement();
String sql = <need help here>
stmt.executeUpdate(sql);
}
catch (SQLException e) {
}
}

not sure how to type the code for String sql
with columnNames, columnType as arrays...
should i actually for-loop it??

 

[Franco]

so far.. i got

String sql = "CREATE TABLE " + tableName + "(" + columnNames + " VARCHAR(32))";

i know it's wrong , but then not sure how i should write it...
another word... stucked :)

for (int i = 0; i < columnNames.length; i++) {
    sql += columnNames[i] + " " + columnType[i] + ",";
}
sql += ");";
