First of all clear the area - there is no such a thing 'phpmyadmin' database... phpmyadmin is a front-end to manage databases of different kind...
So first - see what database do you use, and based on your code sample it is a SQL flavor, probably MySQL or variant (MariaDB)...
The next step is to search for the combination of 'Java', 'MySQL' and 'INSERT'...
This sample shows how to inject values from local variables in a prepared SQL statement:

Java

String sql1 = "INSERT INTO kunden (name,nachname) VALUES('"txtfldVorname.getText()"')";

First of all, you need to learn Java. Search for Jaba string concatenation.

secondly, not a solution to your question, but another problem you have.
Never build an SQL query by concatenating strings. Sooner or later, you will do it with user inputs, and this opens door to a vulnerability named "SQL injection", it is dangerous for your database and error prone.
A single quote in a name and your program crash. If a user input a name like "Brian O'Conner" can crash your app, it is an SQL injection vulnerability, and the crash is the least of the problems, a malicious user input and it is promoted to SQL commands with all credentials.
