Explanation / Answer

public static void main(String[] args) {
Scanner s = new Scanner(System.in);
int computer, user;
  
System.out.print("scissor (0), rock (1), paper (2):");
user = s.nextInt();
computer = (int)(Math.random() * 3);
  
if(computer == 0) {
System.out.print("The computer is scissor.");
} else if(computer == 1) {
System.out.print("The computer is rock.");
} else if(computer == 2) {
System.out.print("The computer is paper.");
}
  
if((user == 0 && computer == 2) || (user == 1 && computer == 0) || (user == 2 && computer == 1)) {
if(user == 0) {
System.out.print(" You are scissor. You won.");
} else if(user == 1) {
System.out.print(" You are rock. You won.");
} else if(user == 2) {
System.out.print(" You are paper. You won.");
}
} else if(user == computer) {
if(user == 0) {
System.out.print(" You are scissor too. It is a draw.");

System.out.print(" You are rock too. It is a draw.");
} else if(user == 2) {
System.out.print(" You are paper too. It is a draw.");
