You could also use a loop.
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import java.util.Arrays;
import java.util.List;
public class MultiTry {
public static String test(List<String> constr, String un, String pw) {
for(String constr1 : constr) {
try(Connection con = DriverManager.getConnection(constr1,
un, pw)) {
// do something with connection
return constr1 + " worked";
} catch (SQLException e) {
// nothing => go next connection string
}
}
return "Houston we got a problem";
}
public static void main(String[] args) {
String res =
test(Arrays.asList("jdbc:mysql://localhost:3308/Test",
"jdbc:mysql://localhost:3307/Test", "jdbc:mysql://localhost:3306/Test"),
"root", "");
System.out.println(res);
}
}
