Suppose I have a java class(TabsAsset) with 20 fields. Then what could be the size of object when I initialize the object.
TabsAsset ta = new TabsAsset();

Formally, it's implementation-dependent, and invisible from Java. Practically, assume 32 bits for each member, plus a 32-bit pointer to the class record, and that will certainly be in the right ballpark.
