Java Constructor Initialization? [duplicate]

Question

Any constructor must explicitly initialize all fields of a class. (Java)

Is this statement true or false? And Can someone please explain why? I do not understand the question.

This statement is false, because all the fields of a class are initialized to their default type values. A reference on an object is initialized to null, an int to 0, a double to 0.0 etc...

First of, please try it.

To answer the question: No. A constructor does not have to initialize all fields.

After the construction of an object all final fields must be initialized.

All non-final variables have default variables in Java. Reference
