problem: read a text file line by line and spilt words

[No Signal X]

hello

i'm having a problem in reading a text file line by line with splitting words, counting the number of lines & words and saving the position of each word


i've started with this :

public void readlineandword() throws IOException{
		BufferedReader rd = new BufferedReader(new FileReader("t1.txt"));

		String line = rd.readLine();
		Scanner read =	new Scanner(line);
		String word1 = read.next();
		System.out.println(word1);
		String word2 = read.next();
		System.out.println(word2);
	}

anyone could help please ? =(

[miss java]

anyone could help please ? =(

i have the same problem !

[coder44]

you can also use like that;

String line = rd.readLine();
char [] words = line.split(" "); 
system.out.println(words[0]);
system.out.println(words[1]);

thanx

what i'm missing are lines & words counter

cuz I have to create an array with a list inside each element of the array

and every list contains words that have the same number of Characters

for example : and , eat , cat .. are inside a list in index 0

[coder44]

if you use split function you should also use parameters for parsing. In your example and, eat, cat words seperated with space and comma. You must give this arguments to split function. For example;

char [] delims = {"," , " "};
line.split(deli ms);

thanks a lot coder44 you've helped me a lot

still wondering about the counters cuz I have to save the number of line & position of each word

i.e.:
coder44 have helped me
he is very helpful guy

the word "very" is in 2nd line , 3rd word

I just need the counters >.<"
