• Java MessageDigest result does not stay constant

  - by user344146

  I've got this function for encrypting passwords in Java, but somehow when I call MessageDigest, it returns a different result every time even though I call it with the same password. I wonder if I am initializing it wrong somehow. public String encrypt (String password) { MessageDigest md = MessageDigest.getInstance("SHA-1"); md.reset(); md.update(password.getBytes(Charset.forName("utf-8")),0,password.length()); String res = md.digest().toString(); }

• Why doesn't Java warn about a == "something"?

  - by Marius

  This might sound stupid, but why doesn't the Java compiler warn about the expression in the following if statement: String a = "something"; if(a == "something"){ System.out.println("a is equal to something"); }else{ System.out.println("a is not equal to something"); } I realize why the expression is untrue, but AFAIK, a can never be equal to the String literal "something". The compiler should realize this and at least warn me that I'm an idiot who is coding way to late at night.

• Java Definitions

  - by Brian

  I just had a test on java and we had to give the definition of 1) Static: 2) IOExcepion: What I said for static was...a static method is used to define a method as a class method. And I got it wrong so I asked my teacher and he said he wants the actually definition of static not a static method, class or variable just static. Can someone tell me the definition of this and for IOException please Thanks.

• Java: Converting UTF 8 to String

• Simple way to do SURBL lookup from Java?

  - by StaxMan

  I am reading about SURBLs (known spam hosts), for purpose of classifying spam, as a batch process. Main access method seems to be via DNS lookups. I was wondering what's the usual way to do such lookups from Java code.

• Java: "implements Runnable" vs. "extends Thread"

  - by goosefraba19

  From what time I've spent with threads in Java, I've found these two ways to write threads. public class ThreadA implements Runnable { public void run() { //Code } } //with a "new Thread(threadA).start()" call public class ThreadB extends Thread { public ThreadB() { super("ThreadB"); } public void run() { //Code } } //with a "threadB.start()" call Is there any significant difference in these two blocks of code?
