Directly package name?

[Jack_Tauson_Sr]

Hi,

In the following code:

public String sort(String s){

char[] content = s.toCharArray();
java.util.Arrays.sort(content);
return new String(content);

}

Is there any way to write java.util.Arrays.sort(content in a different manner?

They have written the package name only directly. Looks weird, huh?

Please clarify.

Hint: imports.

Thanks!

One more question:

Why the return type is like this :"return new String(content);"


Why they have mentioned "new" . Can anyone please explain the whole statement viz "return new String(content);" ?

Thanks

Also tell me the other way to do the same.

Thanks!

Addressing a couple of things here:

First of all, imports are a great thing! However, you'll have a hard time to tell the compiler which sort method you want to use, as the one that is (or will be) executing is also called 'sort'.
Second, the method declaration says that you will be returning a String object. Since content is an array of chars, you have to convert them to a String in order to return it (or else the compiler will complain).

Basically, "new String(content)" means that "Hey, I'm creating an object! Its type will be String with 'content' parameter!". When creating a String object, one of its' constructors accept a char array, which you pass along. To put it in plain English, its like "here's a String object that I just made from a char array".
