One assigns a value to a variable when it is defined.
The other does not and lets the compiler give a default value to the variable.

integers are assigned 0 value by default, and objects (String is one of) are assigned null by default.
So there is no difference if you write:
int age = 0;
and
int age;

It depends on if the variable is at the class level or inside of a method. Local variables must be given an initial value.
