Put chars from String into alfabetical order

Hi, Im stuck.
I want to have a method with:
- a parameter String s
- in the body it breaks the String s apart into chars then the chars
are put into alfabetical order.
- the return would give a String in alfabetical order.

In other words:
private String scramble(String s)
{
// put the chars from the string into alfatbetical order (black box)
return s;
}

Any suggestions?

Regards,

Michael (The Netherlands)

Read the API documentation for each of these:

String method toCharArray. java.util.Arrays, String constructors.

Thanks, these libraries are great :D
My solution:

private String scramble(String s)
{
    int i;
    String result ="";
    char [] chararray;
    chararray = s.toCharArray();
    Arrays.sort(chararray);

    for(i=0; i<s.length(); i++)
    {
result+=chararray[i];
    }
    return result;
}

You can make this better by taking another look at the String constructors.

Depending on what sort of course this program is for, your professor may want
you to implement your own sort rather than using a library implementation.

you could look on this as:

1. how do I convert String to char[] ( see
http://mindprod.com/applets/converter.html )

2. how do I sort the char[] (see http://mindprod.com/jgloss/sort.html
)

3. how do I convert the char[] back to a String ( see
http://mindprod.com/applets/converter.html )
