Question

Good afternoon,

I need assistance find the correct answer to the following question to an entry-level Java assignment as I am confused about how to find it.

Thank you!

Q3 Assume a static method in a Java class. Which of the following statements would cause the method to be erroneous? 2 Points The method calls another static method in the same class The method is called from another non-static method The method accesses a non-static attribute in the same class The method accesses a static attribute in the same class Q4 Given the following code and its output, which statement describes better the implementation of class Person? 2 Points Code: Person p = new Person("Luis"); System.out.println( p ); Output: Luis O Class Person implements the toString method. O Class Person has a private attribute. O Class Person has a method named printin Class Person has zero bugs. Q5 The argument in the main function is: 2 Points public static void main(Stringl] args) O Useless. Useful for passing information when starting the program. Useful to allow programs to use Strings. Not an array

Answer 1

Please comment if you have any doubt

Q3)
   Ans: c) The method accesses a non-static attribute in the same class
       Reason : A static method can only access static memeber but not non-static attribute. So the it will be erroneous.

   Not a), because the method can call another static method
   Not b), because the method can be called from another non-static method
   Not d), because the method can access static attributes

Q4)
   Ans: a) Class Person implements the toString method
       Reason: toString() method is used to return string representation of the Object

   Not b), because it won't return anything
   Not c), because println method can be used to print but the returned value won't be representation for the pbject
   Not d), because bugs has nothing to do with it

Q5)
   Ans: b) Useful for passing information when starting the program
       Reason: The argument is used to pass command line arguments before starting the program

   Not a), because it is not useless
   Not c), because it is not required to use strings in program
   Not d), because it is an array
