Question

6.

• Examine FlipCoin.java:

– Execute the following program and observe the random number that chance generated.

– If chance < 0.5, record the result as “heads”; else record the result as “tails.”

– Repeat this many time.

import java.util.Random;

public class FlipCoin {

    public static void main(String[] args) {

        // 50% chance heads, 50% chance tails

        Random rand = new Random();

        double chance = rand.nextDouble();

        System.out.println(chance);

        }

    }

Exercise 2

• Examine RockPaperScissor.java.

– Perform the following:

– Simulate the RockPaperScissor game by generating a random integer number in the range of 0 to 3.

– Compare the generated number with the following numbers:

– if number=0 : “rock”

– if number=1: “paper”

– if number=2: “scissors”

– Record the result and repeat many times.

public class RockPaperScissor {

    public static void main(String[] args) {

       

    }

}

7.

Exercise 2

• On paper, evaluate the following Java statements

and record the results:

– Math.abs(-1.23)

– Math.pow(3, 2)

– Math.sqrt(121.0) - Math.sqrt(256.0)

– Math.abs(Math.min(-3, -5))

Answer 1

Dear Student ,

As per the requirement submitted above , kindly find the below solution.

Question 6 :

Here a new java program with name "FlipCoin.java" is created, which contains following code.

FlipCoin.java :

import java.util.Random;
public class FlipCoin { //class

   //main method
public static void main(String[] args) {

// 50% chance heads, 50% chance tails
   //creating object of random class
Random rand = new Random();
//generate random number
double chance = rand.nextDouble();
//checking value of chance
if(chance < 0.5)
{
System.out.println("heads"); //print result
}
else
{
   System.out.println("tails"); //print result
}

}
}

Ex.2 :

Here a new java program with name "RockPaperScissor.java" is created, which contains following code.

RockPaperScissor.java :

import java.util.Random;
public class RockPaperScissor {
   public static void main(String[] args) {
       //creating object of random class
Random rand = new Random();
//generate random number
int number = rand.nextInt(3);
//checking number
if(number==0)
{
   System.out.println("rock");//print
}
else if(number==1)
{
   System.out.println("paper");
}
  
else if(number==2)
{
   System.out.println("scissors");
}
}
