Thread: Need help

Hello, I'm new in programming with Java, i learnt today about if, else if, else and i've got some homework. But one of the tasks is the following: I need to type 3 numbers and if they are euqal to get "yes" and if they are not to get "no". I just don't get how to do this and there's a hint that says to look for information for &&, but i haven't learnt about this or i've missed it . Would be happy if someone of you helps me out a little bit.

Exactly this! Thanks man !

Thanks!

Certainly! Here's a solution using Java:

```java
import java.util.Scanner;

public class Main {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);

System.out.println("Enter three numbers:");
int num1 = scanner.nextInt();
int num2 = scanner.nextInt();
int num3 = scanner.nextInt();

if (num1 == num2 && num2 == num3) {
System.out.println("yes");
} else {
System.out.println("no");
}

scanner.close();
}
}
```

This program first prompts the user to enter three numbers. Then, it compares if all three numbers are equal using the `==` operator and the logical AND operator `&&`. If they are all equal, it prints "yes", otherwise, it prints "no". Make sure to input integers when prompted!

If you're still struggling with your Java assignment and need further assistance, there are plenty of resources available online to help guide you through. Consider seeking out additional tutorials or forums where you can ask questions and learn from others' experiences. Sometimes, a different perspective can make all the difference in understanding a concept. Keep practicing, and you'll get there! Additionally, professional assistance from reputable sources like programminghomeworkhelp.com can provide valuable insights and support when tackling complex assignments. Just remember to approach such resources with caution and verify their credibility. Happy coding and good luck with your Java assignment!

Sure, I can help you with that! Here's a simple solution using if-else statements:

```java
import java.util.Scanner;

public class Main {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);

System.out.println("Enter three numbers:");
int num1 = scanner.nextInt();
int num2 = scanner.nextInt();
int num3 = scanner.nextInt();

if (num1 == num2 && num2 == num3) {
System.out.println("yes");
} else {
System.out.println("no");
}

scanner.close();
}
}
```

In this code, we first prompt the user to enter three numbers. Then, we use if-else statements to check if all three numbers are equal. If they are, we print "yes", otherwise we print "no". The && is a logical AND operator which checks if both conditions on its left and right sides are true. So in this case, it checks if all three numbers are equal.
