Does Java create another strong reference instance from get() of WeakReference instance

Question

For example,

WeakReference<Obj> weakObj = new WeakReference<>(obj);
Obj obj2 = weakObj.get()

In this example obj2 is strong reference type?

If yes means GC is not able to remove this reference until its parent get GCed?

Yes, it's a normal reference. If you `get` the object and keep a normal reference to it, then it will not be garbage collected. — khelwood, Sep 28 '20 at 08:54

Yes

Default references are strong references

Your weakObj is a WeakReference, and yes, get() returns a standard reference.
