My comparison seems to be wrong

Question

I'm trying to compare to functions. Each function have this: return returnArr.toString(); as a return, which are strings both of them.

if ( moveRight() == paintFood(235,10,"blue") ){
alert("Food!")
};

But it's not the same like this one:

if ("A" == "A"){
alert("Right comparison");
};

Why ???

Use ".equals()" function. See this: http://stackoverflow.com/questions/513832/how-do-i-compare-strings-in-java — mfruizs, Aug 25 '15 at 13:06
Not to sound condescending, but a modicum of (consistent) [indentation](https://en.wikipedia.org/wiki/Indent_style) wouldn't go astray. — jub0bs, Aug 26 '15 at 09:54

new String("a") == new String("a")

evaluates to false.

Try

if ( moveRight().valueOf() == paintFood(235,10,"blue").valueOf() ){

instead.

Thanks for your help. Problem solved meanwhile. The if condition is put within a function to runs it whether it is needed, which the if condition only was not at the right place:

function check (){
if ( moveRight() == paintFood(235,10,"blue") ){
alert("Food!")
};
};
