Hello I have a method that returns an array that contains values and i want to add those values in another table but it shows the following exception :

java.sql.SQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'application JAVA','','0','0','0','0','2','','','0')' at line 1

The prob is in this part : +tickets.get(i).getContent()+ because when i replace it with “test” or whatever it works well
I did a main test to see if +tickets.get(i).getContent()+ and it return the values that i want
also the type of the column that I want to insert in it’s string
