java - getBoolean(String str) and valueOf(String str) of Boolean class gives different output

Question

I am surprised to know that getBoolean() and valueOf() method returns different results for the same input string.

I have tried to pass the "true" to both the methods. But getBoolean() gives me false output whereas valueOf() gives me right output that is true. Why?

                                     The API-documentation is your friend.

• Boolean.getBoolean probably doesn't do what you think it does:

  Returns true if and only if the system property named by the argument exists and is equal to the string "true".

• Boolean.valueOf is probably what you're looking for:
  

  The Boolean returned represents the value true if the string argument is not null and is equal, ignoring case, to the string "true".
