About Arrays.toString(String[]) method

Hi all,

I am using Arrays.toString(String[]) method to display the information in logs. But I am getting an error like 'the method toString() in the type object is not applicable for the arguments(String[])' in eclipse, when I use this method. What is the wrong with this?

Regards,

Hi Shashi,

it's difficult to tell you the exact problem without knowing the bit of code which makes you trouble. Anyway the Arrays.toString() methods need one parameter which has to be an array of some type. Are your "log entries" arrays of string or what? Take a look at the )]API doc then you can surely figure it out yourself

The toString methods have only been added in Java 5.0. If you are using Java 1.4 or below, there is only one toString() method and that's the one inherited from Object. And that isn't static of course.

Hi Marco,

See the code here I am using.
String str = Arrays.toString(obj.getIDs()); LogUtil.printLog(meth,str);
Where obj.getIDs() returns string array. printLog() method takes the arguments string,string. meth variable also a string.


Here in first line eclipse is showing me an error.

and one more thing..

I am using java 1.4 version. But Arrays.toString() is since 1.5 version right? then is there any way to get the same work done?

Hi Shashi,

I think you can do two things to get this done:

1) Use Java >= 1.5 if possible.

2) Write your own helper class/method which takes your array of Strings and returns a concatenated String containing all the Strings of the array. I think this wouldn't be to difficult.

Thank you,

I did the second thing..
