    Java: Is reading String by String possible?

    I couldn't find anything out there, except reading char by char or char array with specified length. I need to read Strings from a text file like this:
    Code:
    string firstName, lastName;
    infile >> firstName >> lastName;
    I thought I could use *Scanner* but that's only available in java 1.5.

    thnx in advance

    that link is a good start but it reads line by line. if you want to separate strings (by spaces or any other char) you may want to consider a StringTokenizer.

    Code:
    import java.io.*;
    import java.util.StringTokenizer;
    
    public class Foo {
        
        public static void main(String [] args) {
    	if(args.length != 1) {
    	    System.err.println("usage: java Foo file");
    	    System.exit(1);
    	}
    
    	try {
    
    	    BufferedReader in = new BufferedReader(new FileReader(args[0]));
    	    String line;
    	    
    	    while( (line = in.readLine()) != null ) {
    		StringTokenizer toker = new StringTokenizer(line); // uses white space delimeter by default
    		while( toker.hasMoreTokens() )
    		    System.out.println(toker.nextToken());
    	    }
    	} 
    	catch(IOException e) {
    	    e.printStackTrace();
    	}
        }
    }

    you're right. I started copying the code then I realized it reads *line by line*
    well I guess I have to use your method, that sucks..just kidding
