Thread: Getting length of individual token?

Thanks for the feedback, but my problem was that I didn't know how to get the length of each token. What function can I use to do so?

Read the API for String, in particular the length() method.

I tried: "count = sinput2.length();" and "count = sinput2.length;" and it says it cannot find the symbol of length. I've used length for arrays and normal strings and it worked; I'm not sure why it's erroring up for tokens, though.

You have to get the token, and then check the size.

StringTokenizer sinput2 = new StringTokenizer(sinput);
String temp = sinput2.nextToken();
System.out.println(temp.length()); //There is no size() method for the String type. Instead, use length()

This is what I came up with so far:

while(sinput2.hasMoreTokens())
    {	
      String temp = sinput2.nextToken();
      System.out.println(temp.length());
      count += temp.length();
      if (count > winput)
      {
      	System.out.println();
      }	
      System.out.print(sinput2.nextToken() + " ");
    }

The problem is, if I type something like "Hello I like to eat food," it will skip every other token (i.e. it will only consider "Hello," "like," and "eat"). This makes it impossible for me to find every individual one and calculate the total length.

You need to change System.out.print(sinput2.nextToken() + " "); to System.out.println(temp + " ");

Okay, left-justification is working fine! Now I need to include right-justification and centered text. My right-justfication code is as follows:

public static void Rformat(int winput, String sinput)
  {
    int i = 0, count = 0;
 
    // Print out one space to the right since we're filling the entire line
    for (i=2; i <= (winput + 1); i++)
    {
  	  System.out.print("a");
    }
 
    System.out.println();	
    StringTokenizer sinput2 = new StringTokenizer(sinput, " ");
 
    int spaces = 0; // Variable for storing how many spaces we should make
 
    String text = null, space = null;
 
    while(sinput2.hasMoreTokens())
    {    
      String temp = sinput2.nextToken();
      count += temp.length() + 1;
 
      if (count < winput)
      {
	    text = (text + temp + " ");
      }
      else
      {
	  // Find out how many spaces we should put on the line
        spaces = (count - winput);
 
	  // Move all the text to the right one if the line is full
        if (spaces == 0)
        {
	      text = (" " + text);
	    }
	    // Put the amount of spaces we're missing for the next word on this line
	    else
	    {
	      // Add the spaces to the text
	      for (i = 0; i <= spaces; i++)
	      {
	        space = (space + " ");
	      }
 
	       // Add the spaces to the actual text
	       text = (space + text);
	    }
 
	    // Print out the text
	    System.out.println(text);
 
	    // Set the text to the new word
	    text = temp;
 
	    // Set the count to the length of the new word
	    count = temp.length();
        }
    }
  }

Now, the code seems fine to me, yet it doesn't work with only one word and it displays "null" 4 times along with the rest of the text when you put in more than one word. Can anyone pinpoint my mistake, please? Thanks in advance!

Thanks for the advice DanBrown.

Unfortunately, I had to study all of last week for midterms, so I didn't have the full 2 weeks I needed to spend on this program. On top of this, I have a lot of other work that needs to be done by the end of the week.

I'm sorry for being so dependent at the moment, but I did put forth effort into the right-justification method. I'm just running low on time and I need to finish this program by then. However, I do analyze the code that is given to me until I understand it, so it's not exactly a copy-paste thing where I have no idea what I just put into my program.
