Comment détecter si une BD MySQL existe en JAVA?

J'ai trouvé la commande est :

SHOW DATABASES LIKE '<databaseName>'

public static boolean searchDatabase(String databaseName) {
    try {
        Statement stmt = connection.createStatement();
 
        // Creates a result set containing all databases named 'databaseName' 
		String sqlQuery = "SHOW DATABASES LIKE '"+databaseName+"'";
 
    	if (DatabaseController.debug) {
    		System.out.println(sqlQuery);
    	}
        ResultSet rs = stmt.executeQuery(sqlQuery);
        System.out.println("rs.getFetchSize() Nombre de lignes dans le select = "+getSize(rs));
        if (getSize(rs)>0) {
        	return true;
        }
    } catch (SQLException e) {
		e.printStackTrace();
    }	
    return false;
}
 
/**
 * Get the number of rows contained in the parameterized ResultSet.
 * 
 * @param rs
 * @return
 * @throws SQLException
 */
private static int getSize(ResultSet rs) throws SQLException {
	rs.last();                 // Jump to last row
	int rowcnt = rs.getRow();  // get the row count
	rs.beforeFirst();          // reset to allow forward cursor processing
	return rowcnt;
