String.trim() method help.....

[arson09]

I'm really confused on why i keep getting the Symbol not found compile era when i compile my code....

What the program is doing so far is basically getting info from a file and printing it on the screen. Then counting the total number of words in the passage and then printing them. In order to do that though, I'm attempting to turn the passage into an array of words.. Thats where I'm having trouble at... I'm attempting to use the trim() method and the split method, but it's not finding the trim() symbol..


The piece of code i'm trying to use is the_words = str.trim().split("\\s+");... Its at the end of the code

public class passage
{

   public static void main(String[] args)
   throws java.io.IOException
   {

   // Declare Variables

      int i;
      int num_lines = 0;
      String infilename;
      String str [] = new String [1000];
      String [] the_words;

   // Establish keyboard input stream

      Scanner sc = new Scanner(System.in);

   // Get required data items from user

   // Prompt user for input file name

      System.out.print("Enter name of text file: ");
      infilename = sc.nextLine();
// Check for existence of the file

      File infile = new File(infilename);


      if(!infile.exists())
      {

            System.out.println("The file" +infilename+ "does not exists.");
         System.out.println("Quitting now. Please try again.");
         System.exit(1);
      }


    //Open the file for reading

      Scanner fsc = new Scanner(infile);

    //Read the data in the file line by line

      while (fsc.hasNext() )
      {

           str[num_lines] = fsc.nextLine();

        num_lines ++;

      }

           fsc.close();

   // Print text passage

      for(i=0; i<=num_lines; i++)

        System.out.println(str[i]);

   // Count the total number of words in passage

      for(i=0; i<=num_lines; i++)
        the_words = str[i].trim().split("\\s+");

      }
            System.out.println(the_words.length);


   }

}

The error tells you what you're doing wrong -- you're trying to call trim on a String array, not on a String.

edit: then we can talk about the other errors that are present....

How else could i possibly do what I'm trying to do then? In order to print the text info from the file onto the screen exactly how it's written in the file, don't i have to create the array?

But What does it mean to call trim() on a whole array? It's meaningless. You can only call trim on the Strings held as items in the array, not on the whole array itself.

[Fubarable]

So again, call trim() on the String items in the array, not on the array itself:

    for (i = 0; i <= num_lines; i++) {
      the_words = str[color="red"][b][i][/b][/color].trim().split("\\s+");
      System.out.println(the_words.length);
    }

LOL, but i see now that the program does have the other eras that you were talkin about..
