        static boolean hasFever(){
            if(temperature > 36.8){
                return true;
            }else{
                return false;
            }
        }
  
        static void displayTrue(){
            System.out.println("Walang Syang Sakit");
        }
  
        static void displayFalse(){
            System.out.println("My Sakit Sya");
        }
    }

Mga Sir Pa Help Naman Po Medyo naguguluhan lang.

Sample nag input ako ng 45.6
Ang nirereturn nya ay false
Pero kung 45.6 > 36.6
Diba true sya. Pero bakit naging false
Kasi naka asign po ba hasFever ko sa == to false. Gusto ko lang po kasi maklaro.
Salamat po pala and have a good day and gob bless you all.

good day, did you try to convert the `temperature` variable to double using the parse method?
because basically, 45.6 is greater than ( > ) 36.6 which is probably true.

static void higherFever() {
    if(hasFever()==false){
        displayTrue();
    }else{
        displayFalse();
    }
}

the hasFever has a value of true which means hasFever()==false will result in false because true is not equal to false

you can do something like

static void higherFever() {
    if(hasFever()){
        displayTrue();
    }else{
        displayFalse();
    }
}

or

static void higherFever() {
    if(hasFever()==true){
        displayTrue();
    }else{
        displayFalse();
    }
}

or

static void higherFever() {
    if(hasFever()!=false){
        displayTrue();
    }else{
        displayFalse();
    }
}

the first one is a great practice because in the expression you're giving the value which is true or false so there is no comparison operator used which means if the boolean expression of hasFever is false then it will go to else statement otherwise it will go to true statement.


I hope it helps.
