#Use String#isEmpty()

To check if a String is empty, you could use either of these:

s.length()<1 // 12 bytes s.equals("") // 12 bytes 

However, using .isEmpty() is one byte shorter:

s.isEmpty() // 11 bytes 

Note that for Lists it's still shorter to check the size instead of using isEmpty():

l.size()<1 // 10 bytes l.isEmpty() // 11 bytes
