Longest word in a program...

hi...

i have here an example of a java program that finds the longest string in a String array...

Code:

---

    public class StringTest
  {
     
      public static void main (String [] args)
      {
        String[] k = new String[10];
        int indexMaxLength = 0;
        int i;
             
        k[0] = "asdfasdfasdfasdfasdfasdfasdfasdf";
        k[1] = "asdfasdf";
        k[2] = "asdfasdfasdfasdfasdfasdfasdfasdfasdfasdf";
        k[3] = "asdfasdfasdfasdf";
        k[4] = "asdfasdfasdfasdfasdf";
        k[5] = "asdfasdfasdfasdfasdfasdf";
        k[6] = "adsdf";
        k[7] = "adsdf";
        k[8] = "asdfasdfasdfasdfasdfasdfasdfasdfasdf";
        k[9] = "asdfasdfasdfasdfasdfasdfasdf";       
             
        for(i = 0; i < k.length; i++)
        {
            if(k[i].length() > k[indexMaxLength].length())
            {
              indexMaxLength = i;
            }                       
        }               
        System.out.println(indexMaxLength);
      }
  }

any ideas on how to change this program to find the longest word in a sentence inputted by the user??

a simple help would be great...

Have a look at the String.split( ... ) method; you can split the String on something sensible (e.g. one or more spaces, i.e. \\s+) and you have got your array back.

Try this:

Code:

---

String[] yourArray= yourString.split("\\s+");

---

... and read the API documentation for that method.

is string.spilt the only way??

'cause our prof told us that the coverage of this problem is "objects and input/output" and 'control structures"...i can't find string.split in those coverages...

Of course using the String.split( ... ) method isn't the only way; you can always do it yourself; you have to use a clever loop that finds the first non-space character in the String and the first space character to the right of it. You can use the String.substring( ... ) method to chop that part from the String (you found a word) and continue to the right of that space character and repeat your loop, but I find it a bit mechanical at best ...

kind regards,

Jos
