Java Questions - (Has 2 Parts). Based on each code, which answer out of the choices "A, B, C, D, E" is correct. Each question has one correct answer. Thank you. Part 1 - Which method do you need to invoke to display a frame (or a "form")? A. displayWindow = true; B. setVisible = true; C. setVisible(true); D. setDisplay(true); E. setShowForm(true);

Instructor note: This lab is part of the assignment for this chapter. HINT: 1). The decision means how many times to flip the coin. 2). Use a random integer variable to indicate the head or tail in each toss. Java Define a method named coinFlip that takes a Random object and returns "Heads" or "Tails" according to a random value 1 or 0. Assume the value 1 represents "Heads" and 0 represents "Tails". Then, write a main program that reads the desired number of coin flips as an input, calls method coinFlip() repeatedly according to the number of coin flips, and outputs the results. Assume the input is a value greater than 0. Ex: If the random object is created with a seed value of 2 and the input is: 3 the output is: Heads Tails Heads Note: For testing purposes, a Random object is created in the main() method using a pseudo-random number generator with a fixed seed value. The program uses a seed value of 2 during development, but when submitted, a different seed value may be used…
