It is said that Java exclusively uses the Pass by value method of parameter passing $($as opposed$)$ in its implementation of functions. How is this possible in light of the fact that Java exclusively uses references variables for working with objects? Wha exactly would happen if the Java development team suddenly announced that the next version of java will switch$-$over to using pass by refrence for reference paramaeters? Give a short example of a piece of Java code $($not complete program$)$ that would be impacted and explain what the consequence would be$?$

In object oriented programming $,$ please explain the difference between an intnce field and a static $($or class$)$ field within the setting of a class defination$>$ Please focus on both the semantic diffrences as well as technical implementation differences $($e$.$g how are they stored in memory $)$ Please provide example of each type.
