Explanation:

class Employee

{

String name;

double salary;

void tostring()

{

System.out.println("Employee:\nName: "+name+"\nSalary: "+salary+"\n");

}

Employee(String n,double s)

{

name=n;

salary=s;

}

}

class Manager extends Employee

{

String department;

void tostring()

{

System.out.println("Manager:\nName: "+name+"\nDepartment: "+department+"\nSalary: "+salary+"\n");

}

Manager(String n,double s,String d)

{

super(n,s);

department=d;

}

}

class Executive extends Manager

{

void tostring()

{

System.out.println("Executive:\nName: "+name+"\nDepartment: "+department+"\nSalary: "+salary+"\n");

}

Executive(String n,double s,String d)

{

super(n,s,d);

}

}

public class test

{

public static void main(String args[])

{

Employee e =new Employee("Neo",12000);

e.tostring();

Manager m =new Manager("Cramster",100000,"Homework");

m.tostring();

Executive ex =new Executive("Chuks",1000000,"Homework");

ex.tostring();

}

}

yes we can change both the color of the value of a cell as well as background color of a cell at the same time .

as we know that excel sheet consists of columns and rows.

and intersection of column and row is called cell.

we can change color of the cell and background of the cell at the same time.

hence the statement that

can a person change color of the cell and background of the cell at the same time is true.
