Java Programming

@cen: wrong again! hehehe it isnt PrintForm, its PrintWriter anyway, i got hold of my problem. so, the step would be reading now the file. how do you delimit using three characters - "[", ",", and "]"?

ill be using FileReader to "read" out the data then probably use StringTokenizer to delimit those three characters.

next would be compare two arrays...
Binary Search Tree...
AVL Tree...
Hash Table...
Linked List..

and more...

im getting 3 hours of sleep every night

Has anyone tried installing and running Java j2se in a 64 bit Linux box? I installed the standard j2se in a 64 bit CentOS and I can't run a gui application. I'm downloading the 64 bit version now but I can't see an i386 version, only an amd64 version is available. My processor is the intel EM64T

My java application ran successfully using the amd64 version of the jdk even with an Intel EM64T processor

Create a class that inherits StringTokenizer object and implements a Clonable. Override the obj.clone() method. After nimo ang instantiate ang imong class (class that inherits StringTokenizer object and implements a Clonable). clone the instance 2 times. So naa na ka'y 3 instance (including the original). Then use each delimiters to delimit the 3 instances.

or

instantiate 3 different StringTokenizer object with the same String parameter and use each delimiter to delimit the 3 instances.

 StringTokenizer object1=new StringTokenizer("[Sample],[text],[from],[istoryans],[cen]",",");
    StringTokenizer object2=new StringTokenizer("[Sample],[text],[from],[istoryans],[cen]","[");
    StringTokenizer object3=new StringTokenizer("[Sample],[text],[from],[istoryans],[cen]","]");
    
    while(object1.hasMoreTokens()) {
      System.out.println(object1.nextToken());
      System.out.println(object2.nextToken());
      System.out.println(object3.nextToken());
    }

Hahahah... keep solving the problem bro. You can do it. Mo-adapt rana ang imong brain. Kung ang tao nga mag-cge og lift sa weight magka-dako man gani ang lawas. Same rana sa atong brain. Once your brain is bombarded with different problems the neurons will re-arrange so that next time you will solve that problem faster. Pero kailangan mo sleep lang gyud ka og tarong. Take it from me.

Good sleep makes good thinking brain. Pero dili gyud malikayan labi na nga mag-OverTime ka. Basta nindot ni organic nga brain ka'y naay ability nga mo-adapt..

[jerx d great]

Pwede man sad ka mag-create parehas ani...

public class HerdOfAnimals implements java.io.Serializable {

  private Animal animal[];

  public void setAnimal(Animal animals[]) {
  // put some array of animals here...  
}

last nalng jud ni bro!! hehehehe
unsaon pag put some array animals bro?? dli man gud ko kabalu kaayo sa array implementation sa java gud! pwede mangayo example?? k ra bro??

Gamay nalang na nga problem bro. Makaya ra na nimo. Trust me.

[jerx d great]

ok tanx!!

i cant bare to detect the bug... whats wrong with my code?

import java.io.*;
import java.util.*;

class ReadRandomNumber {

	public static void main (String [ ] args) throws IOException {

	String fileName;

	File inFile = new File("sample2.txt");
	FileReader fileReader = new FileReader(inFile);
	BufferedReader bufReader = new BufferedReader(fileReader);
	String entryFromFile;

	entryFromFile = bufReader.readLine( );
	StringTokenizer tokens = new StringTokenizer(entryFromFile,",");

	int numberOfTokens = 0;

	while(tokens.hasMoreTokens( )) {
		tokens.nextToken();
		numberOfTokens++;
	}

	String [ ] arrayOfStringTokens = new String [numberOfTokens];
	int [ ] arrayOfIntTokens = new int [numberOfTokens];

	for(int index = 0; index <= numberOfTokens; index++) {
		tokens.hasMoreTokens( );
		arrayOfStringTokens[index] = tokens.nextToken( );
		arrayOfIntTokens[index] = Integer.parseInt(arrayOfStringTokens[index]);
		System.out.print(arrayOfIntTokens[index]); 
	}
	
	bufReader.close( );
	
	}
}

the code simply reads the numbers from "sample2.txt" and puts it in an array. but it seems that my arrays doesnt work... i welcome suggestions.

thanks!

while(tokens.hasMoreTokens( )) {
		tokens.nextToken(); 
		numberOfTokens++; 
	}

Useless bro. Better use int tokens.countTokens();. This returns total number of tokens.

Now look...

	
while(tokens.hasMoreTokens( )) {
		tokens.nextToken(); // Note 1
		numberOfTokens++; 
	}

for(int index = 0; index <= numberOfTokens; index++) {
		tokens.hasMoreTokens( );
		arrayOfStringTokens[index] = tokens.nextToken( ); // Note: 2
		arrayOfIntTokens[index] = Integer.parseInt(arrayOfStringTokens[index]);
		System.out.print(arrayOfIntTokens[index]); 
}

Note 1: Nag-cge ka og gamit sa tokens.nextToken();. Remember ni move ang cursor position ani.
Note 2: Used up na ang cursor sa while loop nimo. So mo-throw ni siya og exception.

better.... use this!

wait!

Try this. It works sa ako...

public static void main (String [ ] args) throws IOException {

	File inFile = new File("C:/cen.txt");
	FileReader fileReader = new FileReader(inFile);
	BufferedReader bufReader = new BufferedReader(fileReader);
	String entryFromFile;

	entryFromFile = bufReader.readLine( );
	StringTokenizer tokens = new StringTokenizer(entryFromFile,",");

    
	String [ ] arrayOfStringTokens = new String [tokens.countTokens()];
	int [ ] arrayOfIntTokens = new int [tokens.countTokens()];
              
	for(int index = 0; index < arrayOfStringTokens.length ; index++) {
		arrayOfStringTokens[index] = tokens.nextToken( ); 
		arrayOfIntTokens[index] = Integer.parseInt(arrayOfStringTokens[index]);
		System.out.println(index +" " + arrayOfIntTokens[index]); 
	}
	
	bufReader.close();
}
