Java – is initialization the same as null initialization?

If you declare such an object:

Object x;

Does it initialize to null?

For example, is will (x = = null) true?

Solution

If x is a field, it will be null by default If it is a local variable, it must be explicitly initialized before using it This is in JLS § 4.12 5: Initial values of variables
