Question on when toString() method is called

The above code prints
Krishna
Inside String method

I umderstand StringBuilder has it's own toString method so it calls that method and prints Krishna . I am trying to find out what triggers calling of toString method. println method calls toString method on the argument that is passed ? I checked API .println method actually calls Strin.valueOf methos on the argument that is passed. Can someone explain and trace how exactly toString method is called ?

Thanks,
Veena

According to the documentation for String.valueOf(Object obj), if the argument is null, then a string equal to "null" [is returned]; otherwise, the value of obj.toString() is returned.
