Chapter 9.7, Problem 9.7.1CP

Program:

//class definition

public class F {

//data members

int i;

static String s;

//define a method

void imethod() {

}

//define a static method

static void smethod() {

}

}

// to print the result

System.out.println(f.i);

// to print the result

System.out.println(f.s);

// print the result by accessing the value using instance variable

f.imethod();

// print the result by accessing the value using instance variable

f.smethod();

System.out.println(F.i);

System.out.println(F.s);

F.imethod();

F.smethod();

Explanation:

Statement 1:

System.out.println(f.i):

• As “f” is the instance of class “F”, the value of the member variable “i” can be accessed through the instance “f”.

Hence, the above the statement is “Correct”.

Statement 2:

System.out.println(f.s):

• As “f” is the instance of class “F”, the value of the member variable “s” can be accessed through the instance “f”.

Hence, the above the statement is “Correct”.

Statement 3:

f.imethod():

• As “f” is the instance of class “F”, method “imethod()” can be accessed through the instance “f”.

Hence, the above the statement is “Correct”...
