To use the Java SQL stripper, just paste in your Java formatted SQL string into the textbox on the left, then click convert. The example given converts the following String into a formal SQL query.
"SELECT * " + " FROM USERS u" + "INNER JOIN CODE cd ON cd.userid = u.id " + "WHERE u.id in ('1','2') ";
SELECT * FROM USERS u INNER JOIN CODE cd ON cd.userid = u.id WHERE u.id in ('1','2')
Alternatively, you can just paste in SQL into the left textbox, select the SQL to Java radio button, it will convert the raw SQL into a Java string so you can just paste it into your code.
