Thread: BufferReader, histogram

Hi, i have an assignment where i have to do a histogram, that is i receive a text and must count the times each word in the text appears. This method receives a BufferReader and a BufferWritter, what i did so far is transform the buffer reader into a string and i tried some things already, but couldnt find a solution, and i would like to know if u have some ideas to help me.

	public static void histogram( BufferedReader in, BufferedWriter out ) throws IOException{
 
 
		String insert;
		StringBuilder sb= new StringBuilder();
		String [] word= new String [1000];
		int [] counter = new int [1000];
		int k;
 
		while((insert=in.readLine())!=null){
			sb.append(insert);
			sb.append("\n");
		}
		insert = sb.toString();
 
// this was my first try
		k = 0;
		for(int i =0; i<insert.length(); i ++){
			if(Character.isLetter(insert.charAt(i)))
				;
			else{
				for(k =0; k<words.length; k ++){
					if(words [k] == insert.substring(begin , i))
						counter[k]++;
					if(words [k] == null)
						words [k] = insert.substring(begin , i);
				}
			}
		}
 
//this one was the second
		words = insert.split(" " , 1000);
		k = 0;
		for(int i =0; i<word.length; i++){
			out.write(word[i] + ": " + Integer.toString(counter[i]));
			out.newLine();
		}
	}

There is somethings missing that i dont know how i can do, in the first try i tried to seperate the text in words while the "for" was running the string and counting how many equal words appear; in the second i tried to seperate the full string in words and then count, but in this case there were too many words to the array.

Thank you for helping

It was supposed to be words instead of palavras, when i do the insert.split() i dont define the length of words, and it gives an error of OutOfBonds,

String [] word;
 
words = insert.split(" " , 1000);

with i separate the string whenever there is a " ", but sometimes apear ' " ' and it prints the string "The, for example, and the last String of the array is the rest of insert, containing a lot of words yet.


And when i run without the spilt(), i get only the first word 1000 times. I forgot to say, i put 1000 as length, because it is given to me a max of 1000 diferent words.
