            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 E×ρréššion you're giving the value which is true or false so there is no comparison operator used which means if the boolean E×ρréššion of hasFever is false then it will go to else statement otherwise it will go to true statement.


I hope it helps.

Thanks for the explanation sir.
