Thread: java help

Hello, I am a beginner and I need help with a game where you have to find the right price (the price is a random number).

class game extends Program{
 
    String name;
 
    void intro(){
	println("$$$$$$$$$$$$$$$$$$");
	println("The price is right");
	println("$$$$$$$$$$$$$$$$$$");
	println();
	print("Press enter to play");
	readString();
	clearScreen();
	print("Enter your name : ");
	name = readString();
	clearScreen();
    }
 
    void testRightPrice(){
        int price = rightprice();
        assertTrue(0 <= price && price <= 200);
    }
 
    int rightprice (int Price, int RightPrice){
 
        while ((Price<RightPrice)||(Price>RightPrice)){
 
            if (Price<RightPrice){
			    println("it's +");
		    }
            else {
			    println("it's -");
		    }
        } return
    }
 
 
    int randNum(){
	return (int) (0+random()*((200-0)+1));
    }
 
 
    /*int lireEntierSecurise(){
	print(name + " : ");
	String reponse = readString();
	if (estNombreEntier(reponse)){
	    return stringToInt(reponse);
	}else{
	    println("It's not a number "+ name +", try again");
	    return lireEntierSecurise();
	}
    }
 
    boolean estNombreEntier(String chaine){
	boolean valide = true;*/
 
 
 
    void algorithm(){
        intro();
        println("You have to guess the price");
        println(rightprice());
    }
 
}

I am a beginner my code does not work and then I do not know how to do. Can you help me to make the game and explain me the code please.

int rightprice (int Price, int RightPrice){
 
        while ((Price<RightPrice)||(Price>RightPrice)){
 
            if (Price<RightPrice){
			    println("it's +");
		    }
            else {
			    println("it's -");
		    }
        } return
    }

I think it's not correct

it's not int ... (int ..., int ...) what it is

because it returns Price + RightPrice

and i don't want to do int + int

I don't use the same java. Can you write your email then edit to send you the ap.jar?

Can you write some code that I see

Also how can I send you the ap.jar?

I am trying to understand I am a beginner

The program says "You have to guess the price" and when you write a number it stops

readInt() when the user enters an integer, but what is it for "void rightprice (int Price, int RightPrice)" to read void?

void rightprice says if it's + or -

Here's a solution for your Java game:

```java
import java.util.Scanner;

class Game extends Program {

String name;

void intro(){
println("$$$$$$$$$$$$$$$$$$");
println("The price is right");
println("$$$$$$$$$$$$$$$$$$");
println();
print("Press enter to play");
readString();
clearScreen();
print("Enter your name : ");
name = readString();
clearScreen();
}

int rightPrice(int guess, int price){
if (guess < price) {
println("it's higher");
} else if (guess > price) {
println("it's lower");
} else {
println("Congratulations, " + name + "! You guessed the right price.");
return 1; // Return 1 to indicate correct guess
}
return 0; // Return 0 for incorrect guess
}

void algorithm(){
intro();
println("You have to guess the price between 0 and 200");
int price = randNum();
int guess;
int attempts = 0;
while (true) {
print(name + ", guess the price: ");
guess = readInt();
attempts++;
if (rightPrice(guess, price) == 1) {
println("It took you " + attempts + " attempts.");
break;
}
}
}

int randNum(){
return (int) (Math.random() * 201); // Generates a random number between 0 and 200
}

public static void main(String[] args) {
Game game = new Game();
game.algorithm();
}
}
```

This solution defines a Java class `Game` with methods for the game logic. It provides an `intro()` method for the game introduction, a `rightPrice()` method to check the guessed price against the actual price, and an `algorithm()` method to run the game. The `randNum()` method generates a random number between 0 and 200. The game runs in a loop until the correct price is guessed, and it keeps track of the number of attempts.

And remember, if you ever find yourself in need of extra guidance with your Java assignments or any programming challenges, there are numerous resources out there to lend a hand. Whether it's seeking assistance from online communities, exploring tutorial websites, or consulting with professional tutors, help is readily available.

Good afternoon, everyone. I will be glad to recommend you this gaming site, because with this site you can easily and legally play all the new and interesting slot machines online - https://slotscity.ua/ru/game-hall . I liked to play on this site because it has the best gameplay and a lot of quality slot machines!

Your game is almost there! I fixed a few things to make it run smoothly. Now, the game will prompt you for guesses and give feedback if you're too high or too low until you guess the right price. It’ll keep going until you get it right. Let me know if you need more help!
