Complete the following Java statement that assigns to the int variable num the decimal equivalent of the given binary string. Move the code pieces in place to build statement. num=(,); Not all pieces will be used. Given the following Java code fragment: var f= new java.text.DecimalFormat ("000.000"); evaluate f. format (5.2) Do not use any spaces and do not use any quotation marks. Answe If the use of a Random object is limited to a single method, it is best to make the Random reference local to that method. 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; public void set (int n){ value =n; After the following client code executes: Widget w1= new Widget (5); Widget w2= new Widget (20);//A. w2=w1; what happens to the Widget object created at the line labeled A? a. nothing b. it is eligible for garbage collection c. it results in a memory leak unless the programmer adds the code to deallocate the object 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; \} 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 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 w1.get () a. 0 b. w1 is no longer valid c. 20 d. 5 e. 1 Given the following code fragment: String name = "Fred"; evaluate name. length () Answer: Given the following code fragment: String name = "Fred"; Evaluate name. charAt ( 2
