Lukas Eder shares his personal tips and habits after more than 20 years of programming, which he groups under the banner of “defensive programming”. Surely he’s not the only one who gets paranoid now and then?

// Bad
if (variable.equals("literal")) { ... }

// Good
if ("literal".equals(variable)) { ... }

IMO code like this hides real bugs, I'd much rather get a null exception and figure out why the variable is NULL instead of been fooled into thinking evreything is working because it didn't crash.
