declares a variable called tokenUrl and initializes it with the empty string. The next if condition uses this variable by

Here "".equals(tokenUrl) evaluates to true. Then, !"".equals(tokenUrl) is always false.

An ever-false value which is ANDed with anything else will always result in false. Hence, the code in the if block is dead code (and can never be reached).
