Java OCA OCP Practice Question 2351

Question

Which of the following examples defines a correct Java class structure? 

a  #connect java compiler; /*from  www  .  jav  a 2s. com*/
   #connect java virtual machine; 
   class Main {} 

b  package java compiler; 
   import java virtual machine; 
   class Main {} 

c  import javavirtualmachine.*; 
   package javacompiler; 
   class Main { 
       void method1() {} 
       int count; 
    } 

d  package javacompiler; 
   import javavirtualmachine.*; 
   class Main { 
       void method1() {} 
       int count; 
    } 

e  #package javacompiler; 
    $import javavirtualmachine; 
   class Main { 
       void method1() {} 
       int count; 
    } 




f  package javacompiler; 
   import javavirtualmachine; 
   Class Main { 
       void method1() {} 
       int count; 
   } 



d

Note

Option a is incorrect because #connect isn't a statement in Java.

# is used to add comments in UNIX.

Option b is incorrect because a package name (Java compiler) can't contain spaces.

Also, java virtual machine isn't a valid package name to be imported in a class.

The package name to be imported can't contain spaces.

Option c is incorrect because a package statement (if present) must be placed before an import statement.

Option e is incorrect.

#package and $import aren't valid statements or directives in Java.

Option f is incorrect.

Java is case-sensitive, so the word class is not the same as the word Class.

The correct keyword to define a class is class.
