java - Why System.out.println("hey s1==s2:"+s1==s2); prints "false" as the output instead of printing "hey s1==s2:false" -

); String s2 = new string ("Shan"); String s3 = "grace"; String s4 = "grace"; System.out.println ("he s1 == s2:" + s1 == s2); Println ("S3 == S4:" + S3 == S4); System.out.println ("s1.equals (s2):" + s1.equals (s2)); System.out.println ("s3.equals (s4):" + s3.equals (s4)); System.out.println ("s1 == s3:" + s1 == s3); System.out.println ("s1.equals (s3):" + s1.equals (s3)); System.out.println ("he s1 == s2:" + true);

Output: 

  false false s1.equals (s2): true s3.equals (s4): true wrong s1.equals (s3): true Hey s1 == s2: true

Why line # 5 results as "O s1 == s2: false" instead of just "false" as output? 

  line 5: System.out.println ("he s1 == s2:" + S1 == s2);

Before resolving operator's priority "s1 = s2:" + s1 before and then s2 For those who go false.

Give it the highest priority to solve it right. Parenthesis is the top priority. 

  System.out.println ("he s1 == s2:" + (s1 == s2));

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
