Please help!!!

Consider the following class definition: public class Widget \{ private int value; public Widget(int val) \{ value = val; public int get() return value; \} public void set(int n){ value =n; \} After the following client code executes: Widget w1= new Widget (5); Widget w2= new Widget (20); w2. set(1); what is the value of the following expression? w1.get() a. 1 b. w1 is no longer valid c. 0 d. 20 e. 5 Each object (instance of a class) maintains its own instance variables. Instance variables are not owned by the class. Select one: True False All instances of a class share the same instance variables. Select one: True False Consider the following counter class: public class Counter \{ private int count =0; public Counter() count =0; \} public void increment() count++; \} public int get() \{ return count; public void reset() \{ \} count =0; \} What is the value of count after the execution of the following code fragment? Counter cnt1 = new Counter(); Counter cnt2 = new Counter () ; Counter cnt3 = new Counter(); cnt1.increment(); cnt1.increment(); cnt1.increment (); cnt2. increment (); cnt3. increment(); cnt3. increment (); int count =cnt1get(); a. 2 b. 5 c. 4 d. 3 e. 1 f. 0 g. 6 What is the name of the special method that programmers can define for a class that enables instances of the class to represent themselves in a human-readable string form? Note: Proper capitalization is important. Do not include spaces or parentheses. Answe A class method of a class may access only class variables of the class, and it does not have unqualified access to instance variables of the class. Select one: True False Consider the following class definition: public class Widget \{ private int value; public Widget(int val) \{ value = val; \} public int get() \{ return value; \} In the following client code, is the object that w references mutable or immutable? Widget w= new Widget (5); a. it is immutable b. it is mutable c. it is both mutable and immutable d. it is neither mutable nor immutable
