Insert data into mySQL table with java

I have a predefined table in a mySQL database:

I am working on saving data inputted from the user to the database but I cant seem to any data to save in the database. With the following code I am trying to update the first row of the database (ID: 1 through OTHER 2: 0). What am I doing wrong?

private java.sql.Connection con = null;
private PreparedStatement pst = null;
private ResultSet rs = null;
private String url = "jdbc:mysql://localhost:8889/deliveryEarn";
private String user = "root";
private String password = "root";

try {
     con = DriverManager.getConnection(url, user, password);
     Statement st = (Statement) con.createStatement(); 

     st.executeUpdate("INSERT INTO incomeCalc " + "VALUES (3, 75, 6, 25, 18.50)");

     con.close();
}

catch (SQLException ex) {
     Logger lgr = Logger.getLogger(deliveryMain.class.getName());
     lgr.log(Level.SEVERE, ex.getMessage(), ex);

 }
