Code That Made Me Cry, #CTMMC™

95% of all code makes me cry. The other 5% are white space.

Broken dates (Java, #50 / 50)

// not really a date, but a Date
Date date1 = new Date(0L);
// really a date, but not a Date
java.sql.Date sqlDate = java.sql.Date.valueOf("1970-01-01");
// really a date, but a Date?
Date date2 = sqlDate;
// a Date with time
date1.getHours();
// a Date without time. <-- throws an IllegalArgumentException.
// Wait, exactly *which* argument is illegal?
date2.getHours();        

Not following subtype contracts, about every type/method/exception name is a misnomer, java.util.Date was already broken, but java.sql.Date just makes it far worse.

Don't let your SQL code make you cry!

Use jOOQ, instead of JDBC.

jOOQ generates Java code from your database and lets you build typesafe SQL queries through its fluent API.
