Plese help JAVA Bolean not working

[Symbolls]

I dont know what to do i need to make this exercise for univarcity and the teacher did not tell us how to do them and i need help plese

import java.util.Scanner;

public class Exercise {
    public static void main(String[] args){
        Scanner input = new Scanner(System.in);
        boolean isCold = input.nextBoolean(); //Is it cold? [true/false]
        boolean isDry = input.nextBoolean(); //Is it dry? [true/false]
        boolean isHard = isDry ^ isCold;
        if (isCold == isDry){
            System.out.print("It is dry\n" +
                    "It is hot or dry");
        }else{

            if (!isCold) {
                System.out.print("It is hot\n" +
                        "It is dry\n" +
                        "It is hot or dry\n" +
                        "It is hot and dry");
                }
            if (!isHard){
                System.out.print("It is hot\n" +
                    "It is hot or dry");
            }
            }

        /* if (isDry^isCold){
            System.out.print("It is hot\n" +
                    "It is dry\n" +
                    "It is hot or dry\n" +
                    "It is hot and dry");
        }*/
    }

I would recommend you look up what the correct operators are first as a very basic step. https://www.w3schools.com/java/java_operators.asp

 

Then you should think about all the possibilities, the program can read 2 booleans isCold and isDry. That means there are 4 possible outcomes.

 

isCold = true AND isDry = false

isCold = true AND isDry = true

isCold = false AND isDry = false

isCold = false AND isDry = true

 

Now you can already see your if statements right there, because that is all the program can read. You just have to figure out what the logical outcomes are of each case. 

 

Here's the first one:

 

if (isCold && !isDry) {

  // no output

}

 

hope you can take it from here

That code seems pretty complicated for what you're asked to do. How about using AND (&&) and OR (||), rather than XOR?

 

final boolean isCold = input.nextBoolean();
final boolean isDry = input.nextBoolean();

// For less mind-fuckery
final boolean isHot = !isCold;

if (isHot) {
    System.out.print("It is hot\n");
}
if (isDry) {
    System.out.print("It is dry\n");
}
if (isHot || isDry) {
    System.out.print("It is hot or dry\n");
}
if (isHot && isDry) {
    System.out.print("It is hot and dry\n");
}

that does make it very neat

Yeah. If you find you have to think about what a variable means every time you want to use it (hot… so… not cold) then it's a good pointer that you should rename it to something more appropriate.
