Rock Paper Scissors

When two people play rock paper scissors, someone wins, loses, or they tie.

There are 9 combinations.

For Player 1:

Player 1	Rock	Paper	Scissors
Rock	Tie	Lose	Win
Paper	Win	Tie	Lose
Scissors	Lose	Win	Tie

We will code Human vs Computer.

Computer generates random numbers so we will use 0, 1, 2, instead of Rock, Paper, or Scissors.

Random random = new Random();

random.nextInt(3);

The computer will choose either 0, 1, or 2.

Human will choose using Scanner.

Below is a chart of human's wins and losses.

|Computer|

Human	0: Rock	1: Paper	2: Scissors
Rock	Tie	Lose	Win
Paper	Win	Tie	Lose
Scissors	Lose	Win	Tie

Each condition will have its own if statement.

if (computer == 0) {
    if (human == 0) ...
    if (human == 1) ...
    if (human == 2) ...
} 


if (computer == 1) {
    ...
}

Better RPS

You will notice that when human == computer, the game is a tie.

Using some math you can also figure out that when human is one more than computer, the game can be a win or a lose...
