Converting Object[] to string in Apache Logger

Question

I have an object array from a Hibernate query that I want to show in a logger message.

I have

//row output
for (Object[] objs : results) 
{
    logger.info(objs.toString());
}

but I get [Ljava.lang.Object;@60cf75a9 for each.

How do I convert the array to a string output?

Don't use the .toString() method of Object[]. Use Arrays.toString()

for (Object[] objs : results) 
{
    logger.info( Arrays.toString( objs ) );
}

That's it thanks. I tried Arrays.toString before and got syntax errors, think i used it with a String.format(). Your example works. – user2568374 Aug 13 '15 at 19:29

You need to over-ride the toString method to suit your needs. Right now it's printing out the memory address of each object in the array.

public String toString() {
//              Return whatever aspect of the object you want to display.
}
