Consider the following class definition: public class Mello \{ public static int melloize(int n){ return 2n3; \} Now consider the following client code fragment: System.out.println(Mello.melloize(19); The literal value 19 in the client's code is known as what? a. a user parameter b. an actual parameter c. a client parameter d. a formal parameter Consider the following class definition: public class Mello \{ public static int melloize(int n){ return 2n3; \} The variable n in the melloize method definition is known as what? a. a user parameter b. a client parameter c. an actual parameter d. a formal parameter In order for all code outside of a class to be able access a method, the method must be declared as wha a. static b. public c. It is not possible for code outside of a class to access the method within that class. d. No special notation is required. e. open Consider the following class definition: public class Mello \{ public static int melloize(int n){ return 2n3; \} Indicate whether each of the following represents a legal Java statement in the context of the given class definition. x and y are properly declared and initialized integer variables. scan is a properly declared and initialized java. util. Scanner object reference. x=Mello.melloize(5)x=Mello.melloize(5,y=Mello.melloize(x);Mello.melloize(x); y=Mello.melloize(x+2); x=Mello.melloize(5.0); x=Mello.melloize(scan.nextInt()); x=Mello.melloize(Mello.melloize(3)); What JUnit method compares an expected result with an actual result? a. test b. assertEquals c. compareEquals d. testEquals e. checkEquals The method call Compute.process (19,4) should return the value 3.5. Considering the imprecision of floating-point arithmetic, complete the statement below that allows JUnit to regard any floating-point number in the range 3.49 to 3.51 as a correct result. assertEquals(3.5,Compute.process(19,4),); Consider the following two method definitions: public static int f1( int n){ if (n1){ s+=2; n; Method f1 is computationally more efficient than f2. Select one: True False Given the following class definition: public class Mello \{ public static int melloize(int n){ return 2n3; \} evaluate the following expression: Mello.melloize(19)
