How to get the initialisation value for a Java Class reference

Question

I have a Class reference for an arbitrary type. How to get that type\'s initialisation value? Is there some library method for this or do I have to rol

You can use Defaults class from guava library:

public static void main(String[] args) {
    System.out.println(Defaults.defaultValue(boolean.class));
    System.out.println(Defaults.defaultValue(int.class));
    System.out.println(Defaults.defaultValue(String.class));
}

Prints:

false
0
null
