Easiest way to convert String to StringBuffer

Hello lads!

Im looking a way to easily convert String to StringBuffer for passing it to different methods.

If it were the other way, I would use

Code:

---

thisMethodTakesString(myStringBuffer.toString());

---

However, I have method that takes StringBuffer as an argument, but my variable is String.

Right now I'm doing

Code:

---

String str = "Hello Java-forums.org";
/* This is where it goes kinda complicated and messy */
StringBuffer sb = new StringBuffer(str);
thisMethodTakesStringBuffer(sb);

---

Is there any simple way to cast String -> StringBuffer without needing to write those needless lines of code?

Thanks.

Did you read the API documentation for the StringBuilder (or StringBuffer) class? They both have constructors that do exactly what you want. Your code snippet already shows its usage.

kind regards,

I did. I know there is constructor StringBuffer(String str) for creating new StringBuffer object and then assigning the String value for it.

Is there however, shorter way to do it?

I tried

Code:

---

thisMethodTakesStringBuffer( StringBuffer(str) );

---

and apparently it doesnt work.

Is it necessary to make one more, needless StringBuffer line with kind of an dummy variable sb that I posted on the first post, or is there some easy way to convert it like StringBuffer's toString() is?

A constructor always needs the 'new' operator:

Code:

---

thisMethodTakesStringBuffer(new StringBuffer(str));
