io stream

read in the single bytes and check if the current byte is a word separator / a space char.

count these separators and finally add 1.

FileInputStream in = new FileInputStream("words.txt");

byte current_byte;

byte separator = " ".getBytes()[0];

int gap_counter = 0;

while((current_byte = in.read()) != -1) {

if(current_byte.equals(separator)) {

gap_counter++;

}

}

System.out.println((gap_counter+1) + " words found in file words.txt");

to make sure that there are no multiple separators ("word1 word2 word3 word4 word5") you might first read in the whole file and use a StringTokenizer to get the number of words:

FileInputStream in = new FileInputStream("words.txt");

byte current_byte;

String whole_file_text = new String();

while((current_byte = in.read()) != -1) {

whole_file_text += current_byte;

}

StringTokenizer tokenizer = new StringTokenizer(whole_file_text, " ");

System.out.println(tokenizer.countTokens() + " words found in file words.txt");

First read the info from file. One way ....

String str;

try

{

DataInputStream in = new DataInputStream(new FileInputStream("1.txt"));

while((str=in.readLine())!=null)

{

System.out.println(str);

}

}catch(FileNotFoundException e){}

catch(EOFException e){}

catch(IOException e){}

if you just need to count words in the string (assuming space delimitation), easiest way to count words is this.......

StringTokenizer st = new StringTokenizer(yourString);

st.countTokens() should return thenumber of words in the string.

If however, the delimiter is not space, use this approach....

int index=0;

int numOccurrences=0;

while(true)

{

index= str.indexOf("if",index);

System.out.println("index is.."+index);

if(index==-1) break;

numOccurrences++;

index++;

}

System.out.println("Num ..."+numOccurrences);
