1. In the following code, suppose that f is an instance of Foo. class Foo int i; static int s; void
imethod) static void s method ) Which of the following statements is(are) incorrect? int t =
f.imethod(); f.smethod(); System.out.println(f.s); System.out.printin(f.i);
Solution
1. answers are option (2),(3),(4). because it is possible to call method and access class variables
using an object of that class. option (1) is wrong.
int t=f.imethod(); // ( this statement is wrong.because in method declaration, its return is void.
but here it is trying to return an integer value )
2. answer is option (1) char[ ] charArray=new char[25];. here an array is declared correctly .
all other options are wrong.
int[ ] words=new words [10]; // ( this declaration is wrong. because its syntax is not correct.it
should write like this int[ ] words=new int [10]; )
char[ ] charArray="computer science" // ( "computer science" is a string not array of
charecters. here array type is declared as char. )
double[3] nums= {3.5,35.1,32.0}; // ( array declaration is not correct . )
3. answer is o ption (4). f.imethod(); . because f is an instance object of the class Foo. a method
can be called by an object. all other options are wrong .
System.out.println(Foo.s) // ( i t is not possible to access an instance variable of a class by using
class name instead of instance object ).
System.out.println(Foo.i) // ( i t is not possible to access an instance variable of a class by using
class name instead of instance object ).
Foo.smethod(); // ( i t is not possible to call a method of a class by using class name instead of
instance object ).
