[Java] Boolean.valueOf("1")

Returns a Boolean with a value represented by the specified string. The Boolean returned represents a true value if the string argument is not null and is equal, ignoring case, to the string "true".



所以，Boolean.valueOf("1") returns false.



有點荒謬又不會太荒謬，能理解又不太能理解，以後看到 Boolean.valueOf() 要特別小心。
