java - Extra variable or existing variable -

-

I want to ask that there is any effect (such as performance) between these two types of code.

Method 1: 

  object object = new object (); // different variable object object2 = new object (); . . .

Method 2: 

  object object = new object (); . . Object = new object (); // Repeat the same variable

Is it different from coding style or any other reason, such as reserve memory, better performance?

In Method 1, you are creating two references and collecting two different objects . Both objects are not eligible for garbage collector.

On Method 2, you are creating a reference and you can allocate a new object and then you create a new object and allocate it in context. Now there was no reference in your first object, so this garbage collector is eligible.

Good luck !!!

javascript - data.match(var) not working it seems -

OK, I have this small block code, which is to scanned a number on the website, but for some reason There is a hip that it is not scanning at all. var regenges = / \ & lt; Span class = "currency-robux" data-to-"item-private-value-price" & gt; ([\ D,]) \ & LT; \ / Span \ & gt; /; Var ValueCiling = Data. Match (reggae); Value-song = number (value slicing location (",", "")); Is there anything wrong with that? This is related to the if statement if (value sling and lieutenant; = price watching) { < P> A function calls to move from there, but for some reason it does not seem to run at all. So I think the Regex is wrong but I'm not sure how. (There is a variable in PriceWinking , this is a snippet from the code.) On the website, I'm trying to remove it. & lt; Span class = "robux" data-plus = "item-privatesale-price" & gt; 115 & lt; / Span & gt; Keep in mind
