Select the best answer.
a. if (6 < 2 * 5)
System.out.print("Hello");
System.out.print(" There");
outputs the following:
i. Hello There ii. Hello iii. Hello iv. There
There
b. if ('a' > 'b' || 66 > (int)('A'))
System.out.println("#*#");
outputs the following:
i. #*# ii. # iii. * iv. none of these
*
#
c. if (7 <= 7)
System.out.println(6 - 9 * 2 / 6);
outputs the following:
i. -1 ii. 3 iii. 3.0 iv. none of these
d. if (7 < 8)
{
System.out.println("2 4 6 8");
System.out.println("1 3 5 7");
}
outputs the following:
i. 2 4 6 8 ii. 1 3 5 7 iii. none of these
1 3 5 7
e. if (5 < 3)
System.out.println("*");
else if (7 == 8)
System.out.println("&");
else
System.out.println("$");
outputs the following:
i. * ii. & iii. $ iv. none of these

Briefly explain what a method is and describe the three main parts of a
method.

By making use of an example, show how method overloading takes place. Also
indicate how overloaded methods can be called from mainline logic.

Use an example to briefly explain the features of a structured program.

Write a python program to create the dataframe and perform Boolean indexing on it.

Write an if-else statement that if userTickets is less than 5, executes awardPoints = 15. Else, execute awardPoints = userTickets. Ex: If userTickets is 3, then awardPoints = 15.
