java - error: incompatible types: unexpected return value -


this question has answer here:

class fibo{

public static void main(string[] args){     int a=0 ,b=1,c=1 ;     for(int i=0; i<=4; i++){          c=a+b ;         c=a ;         a=b;     }     return c ;    }

}

when compile program error:

incompatible types: unexpected return value

what mean?

you cannot return main method; it's return type void

you can make static method return type of int if want specfic use-case work

'hasOwnProperty' in javascript -

i use obj.hasownproperty judge whether object has property, when replaced obj[prop] !== undefined , not normal implementation, ask, why behind method can not use it? object.hasownproperty(prop); object[prop] !== undefined; obj[prop] !== undefined wrong 2 reasons: you can explicitly set property undefined , obj[prop] = undefined; . obj.hasownproperty(prop) return true in case. obj[prop] follow prototype chain, return property that's inherited. obj.hasownproperty(prop) returns true if property exists directly in object, returns false inherited properties.
