I have to write program for a dice game and use a boolean variable in the application class of the dice game that equals true when snake eyes, doubles, and box cars have been meet. I am having a little trouble doing that in my application class so I was wondering if somebody can help me out. This is how my application class looks now:
package classes;
public class DiceGameApp {
public static void main (String [] args) {
DiceGame dice = new DiceGame ();
for (int rollCount = 0; rollCount < 10; rollCount ++) {
dice.roll();
System.out.println("\nYou rolled a " + dice.getDieone()+ " for dice one and a " +dice.getDietwo()+ " for dice two.");
if(dice.getDieone()== 1 && dice.getDietwo()== 1){
System.out.println ("\nYou have rolled snake eyes.");
}
else
{
if (dice.getDieone()== 6 && dice.getDietwo()== 6)
System.out.println("\nYou have rolled boxcars.");
else
System.out.println("\nYou have rolled doubles.");
}
}
}
}
A Boolean variable is a variable, like an int or a string, but whose value is either "true" or "false".
Try this little lump of code, and vary d1 and d2 values, to see the effect:
int d1 = 1
int d2 = 1
boolean snakeeyes;
boolean doubles;
boolean boxcars;
snakeeyes = (d1 + d2 == 2);
doubles = (d1 == d2);
boxcars = (d1 + d2 = 12);
System.out.println("Is this snake-eyes?");
System.out.println(snakeeyes);
// and you can also use it in a logical statement
System.out.println("Is this bpxcars?");
if (boxcars) System.out.println("Yes");
and so on.
It's not clear from your description whether your project calls for one boolean condition for each condition or one for any of them, but I hope this example will illustrate the general method.
To use a boolean variable in your application class to track when snake eyes, doubles, and box cars have been rolled, you can follow these steps:
1. Declare a boolean variable called `isSpecial` and initialize it to false at the beginning of your main method:
```java
boolean isSpecial = false;
```
2. Inside the if-else conditions where you check for snake eyes, doubles, and box cars, set `isSpecial` to true if a special combination is rolled:
```java
if (dice.getDieone() == 1 && dice.getDietwo() == 1) {
System.out.println("\nYou have rolled snake eyes.");
isSpecial = true;
} else if (dice.getDieone() == dice.getDietwo()) {
System.out.println("\nYou have rolled doubles.");
isSpecial = true;
} else if (dice.getDieone() == 6 && dice.getDietwo() == 6) {
System.out.println("\nYou have rolled boxcars.");
isSpecial = true;
}
```
3. After the for loop, you can check if any of the special combinations have been rolled by checking the value of `isSpecial`:
```java
if (isSpecial) {
System.out.println("\nYou have rolled a special combination.");
} else {
System.out.println("\nYou have not rolled any special combinations.");
}
```
Here's the updated code for your `DiceGameApp` class:
```java
package classes;
public class DiceGameApp {
public static void main (String [] args) {
DiceGame dice = new DiceGame();
boolean isSpecial = false;
for (int rollCount = 0; rollCount < 10; rollCount++) {
dice.roll();
System.out.println("\nYou rolled a " + dice.getDieone() + " for dice one and a " + dice.getDietwo() + " for dice two.");
if (dice.getDieone() == 1 && dice.getDietwo() == 1) {
System.out.println ("\nYou have rolled snake eyes.");
isSpecial = true;
} else if (dice.getDieone() == dice.getDietwo()) {
System.out.println("\nYou have rolled doubles.");
isSpecial = true;
} else if (dice.getDieone() == 6 && dice.getDietwo() == 6) {
System.out.println("\nYou have rolled boxcars.");
isSpecial = true;
}
}
if (isSpecial) {
System.out.println("\nYou have rolled a special combination.");
} else {
System.out.println("\nYou have not rolled any special combinations.");
}
}
}
```
By using the `isSpecial` boolean variable, you can track if any of the special combinations have been rolled and provide the appropriate output at the end.
