stringtokenizer

I've got a string that I'm supposed to use StringTokenizer on for a course. I've got my plan on how to implement the project, but I cannot find any reference as to how I will make the delimiter each character. Basically, a String such as "Hippo Campus is a party place" I need to divide into tokens for each character and then compare them to a set of values and swap out a particular one with another. I know how to do everything else, but what the delimiter would be for separating each character? If you really want to use StringTokenizer you could use like below String myStr = "Hippo Campus is a

Hey. You may have recently seen a post by me looking for help, but I did it wrong before, so I am going to start fresh and begin at the basics. I am trying to read a text file that looks like this: FTFFFTTFFTFT 3054 FTFFFTTFFTFT 4674 FTFTFFTTTFTF ... etc What I need to do is put the first line into a String as the answer key. Next, I need to create an array with the student ID (the first numbers). Then, I need to create an array that is parallel to the student ID that contains the student's answers. Below is my code, and I can't quite figure out how to get it to work like this, and I was

I have a question about optimization of my code (which works but is too slow...). I am reading an input in a form X1 Y1 X2 Y2 etc where Xi, Yi are integers. I am using bufferedReader for reading lines and then StringTokenizer for processing those numbers like this: StringTokenizer st = new StringTokenizer(line, " "); int x = Integer.parseInt(st.nextToken()); int y = Integer.parseInt(st.nextToken()); The problem is that this approach seems time inefficient when coping with large data sets. Could you suggest me some simple improvement (I have heard that some integer parse int or regex can be

I'm trying to read a text file and split the words individually using string tokenizer utility in java. The text file looks like this; a 2000 4 b 3000 c 4000 d 5000 Now, what I'm trying to do is get each individual character from the text file and store it into an array list. I then try and print every element in the arraylist in the end. Here is my code; import java.io.BufferedReader; import java.io.FileReader; import java.io.IOException; import java.util.ArrayList; import java.util.StringTokenizer; public static void main(String[] args) { String fileSpecified = args[0]; fileSpecified =

I'm using a Java StreamTokenizer to extract the various words and numbers of a String but have run into a problem where numbers which include commas are concerned, e.g. 10,567 is being read as 10.0 and ,567. I also need to remove all non-numeric characters from numbers where they might occur, e.g. $678.00 should be 678.00 or -87 should be 87. I believe these can be achieved via the whiteSpace and wordChars methods but does anyone have any idea how to do it? The basic streamTokenizer code at present is: BufferedReader br = new BufferedReader(new StringReader(text)); StreamTokenizer st = new

I have a seemingly simple problem of splitting a comma separated String into tokens, whereby the output should include empty tokens in cases where: The first character in the String is a comma. The last character in the String is a comma. Two consecutive commas occur. For example, for the String : ",abd,def,,ghi," should yield the output: {"", "abd", "def", "", "ghi", ""} . I have tried using String.split , Scanner and StringTokenizer for this but each gives a different undesired output (examples below). Can anyone suggest an elegant solution for this, preferably using JDK classes? Obviously I
