A String is an object. A String array is an Array object that holds Strings. A String array is not a String and a String is not a String array. They are two different objects.

Think of an array as a container. It is holding objects of the type you've declared. For example a String array can hold Strings.

Hi kalai,

You can't type cast from String to String array.

If you want create a String array from String means, you can use the following

String[] strArray = new String{ str1 };

Why do you need to do this? Explain how your going to apply it and then maybe I can lead you to an alternative.

So you actually don't want an array with *one* string, but an array that in every string contains one word of the original string?

Hi,
If you just want to find and replace the word with another then you can use replace(word1,word2) method of String/StringBuffer.That wud be easy.
