Converting byte into String

[firelex]

Hello, all!
I'm a newbie in JAVA, can anyone tell me how can a byte[] be converted into String?
The situation is:

... somewhere ....
tst=new String(qwertz);
somemethod(tst.getBytes()) ;
..............................

public void somemethod(byte[] oid)
{
String tmp;

tmp=new String();
tmp=oid.toString();
System.out.println("TEST : " + tmp2);
}
This thing gives me the same as "System.out.println("TEST : " + oid);" How could I get the original string "qwertz" back?

Thanks

Well, it was perhaps a stupid question ... (
But I've found the answer myself and for the case, that someone else the same problem has, I'll put it down :

It is possible to make a String from bytes by inserting these bytes into the constructor of String. In my case the answer was :
[tt]
public void somemethod(byte[] oid)
{
String tmp;

tmp=new String(oid);
System.out.println("TEST : " + tmp);
}
[/tt]
This gives the String back, that has been converted into bytes
