Print an object data in Vector to console???

Helo, the belowing code will print the memory address preceded by "Customer".
Actually, I want to print the name, age, and location. But it did other way. Anyone know what's the prob?
Vector v = new Vector();
v.addElement(new Customer("Paul", 29, "CA"));
v.addElement(new Customer("Ton", 21, "LA"));
for (int i=0; i<v.size(); i++){
System.out.println(closedList.get(i));
}Thank you. :)

U mean i dun need to overwrite the contains, the only
need is just the equals()? I dun know much bout
hashCode()? Which one I should refer?You should override both hashCode() and equals() in your Customer class.

How to use Iterator correctly to print out object attributes from Vector ?

Dear Java People,
I have no compilation errors but am not getting output.
I created a CD class and a Vector to hold all the CDs.
I think perhaps I am using the Iterator incorrectly in the
toSting() method. Below is the driver and CD class
Thank you in advance

Dear InTrueT,
The problem with trying to use
System.out.println()is that it returns void and
toString() requires a String be returned
the error messaage says:
"CD.java": Error #: 354 : incompatible types; found:
void, required: java.lang.String at line 35
your advice is appreciated
NormanYou seem to have misunderstood. toString(), as you say, returns a String. System.out.println(), by a wonderful coincidence of design, accepts a String as a parameter. My suggestion was that you pass the output of one as the input to the other, thus displaying your String on the screen, as I had understood this to be your desire.

Read data from Vector object serialized in a file issue!!

Hi all,
I have two classes :CBase and CHelper class in a package and serializing some information in a file and then reading it. I am facing some problem while reading the data
which was stored using vector of objects. Below is the detailed problem:::::
////////////CHELPER
public class CHelper implements Externalizable, Cloneable {
public string szname;
//..other functions writeexternal read external
////////////CBASE
public class CBase
implements Externalizable, Cloneable {
protected boolean bRead;
protected boolean bWrite;
protected Vector vData;
public void addInstance(CHelper obj) {
vData.addElement(obj);
//..other functions writeexternal read external
I am Serializing all the CBase information in a file and trying to read the contents from this serialized file::::
CBase base = new CBase();
CHelper obj = new CHelper();
obj.setName("HELPER");
base.addInstance(obj); // ADDING THE OBJECT DATA INTO THE VECTOR
base.bRead = true;
base.bWrite = true;
// Writing to the file
FileOutputStream fs = new FileOutputStream("d:\\temp\\Base.txt");
ObjectOutputStream os = new ObjectOutputStream(fs);
os.writeObject(base);
os.close();
//reading from the file
FileInputStream fi = new FileInputStream("d:\\temp\\Base.txt");
ObjectInputStream oi = new ObjectInputStream(fi);
CBase read = (CBase) oi.readObject();
PRINTING THE OUTPUT
System.out.println("Vector = " + read.vData.firstElement().toString());
System.out.println("Write = " + read.bRead);
System.out.println("Read = " + read.bWrite);
The output is something like:
Vector = com.sp.CHelper@14b7453 // WHAT IS THIS ?? GARBAGE ?? NOT ABLE TO ANALYSE :(
Write = true;
Read = true;************
MY PROBLEM:
i.e How to get the information stored in the Vector ? I am getting something "com.sp.CHelper@14b7453 " whereas the expected output should be Vector = HELPER. I am
writing and reading the vector as follows:
// CHELPER
public void writeExternal(ObjectOutput out) throws IOException {
out.writeUTF(szName.toString());
public void readExternal(ObjectInput in) throws IOException,
ClassNotFoundException {
setName(in.readUTF());
Externalize in CBase Classs
out.writeInt(getInstanceCount()); // getting number of objects in the vector
for (int index = 0; index < getInstanceCount(); index++) {
out.writeObject((CHelper)vData.get(index));
out.writeBoolean(bWrite);
out.writeBoolean(bRead);
And reading like this::
int iNumberofInstances; // number of instances
iNumberofInstances = in.readInt();
vData.clear();
// Get the CHelper object and add it into the CFeatureBase vector
for (int i = 0; i < iNumberofInstances; i++) {
CHelper objbase = (CHelper)in.readObject();
vData.add(objbase);
this.bWrite = in.readBoolean();
this.bRead = in.readBoolean();
I suppose that i am correctly WRITING AND READING the data. B/w what can be the problem. All suggestions are welcome/
Thanks,
Rohit

HELPER.This is perfectly normal behaviour if your CHelper class doesn't override the toString() method. The default toString() method in Object just prints the name of the class and a hex representation of the object's hash code.
Add a toString() method to CHelper that returns szname and you should see what you are expecting.

How to print the image data stored in object of 'java.io.File' Class in jsp

I have created a file object for the image file in the system temporary directory.Now I want to display it in my page. please tell,How to print the image data stored in object(in my program it is imgr) of 'java.io.File' Class in jsp

Create a servlet which gets an InputStream of the file and writes it to the OutputStream of the response and call this servlet in `src` attribute. That's basically all.
Here's an example which covers the most of the minimum needs: [http://balusc.blogspot.com/2007/04/imageservlet.html].

I created a vector and added objects, but the vector is empty

I created an object called a facility, it accepts 2 strings in the creator but stores the data as a string and a float. as you can see from the code below, i have tried to create a vector object to contain facilitys and named it entries. when i add objects to this vector, the vectors size does not change, and i cannot access elements of it via their index. but when i print the vector out i can see the elements? what is going on here. i am very confused. ps, if it helps i havent worked with vectors much before.
FacilitysTest.java
import java.util.*;
public class FacilitysTest {
 public static void main (String [] args) {
 Facilitys entries = new Facilitys();
 entries.add("Stage","3.56");
 entries.add("kitchen","5.00");
 entries.add("heating","2");
// System.out.println(entries.firstElement() );
 System.out.println("printing out entries");
 System.out.println(entries);
 System.out.println();
 System.out.println("There are "+entries.size()+" entries");
 System.out.println();
 System.out.println("modifying entry 2");
 entries.setElementAt(new Facility("lighting","1.34"), 2);
 System.out.println(entries);
 System.out.println();
 System.out.println("deleting entry 1");
 entries.remove(1);
 System.out.println(entries);
}the following is what happens when i run this code.
the number (0,1,2) is taken from a unique number assigned to the facility and is not anything to do with the facilitys position in the vector.
printing out entries
Facility number: 0, Name: Stage , Cost/Hour: 3.56
Facility number: 1, Name: kitchen , Cost/Hour: 5.0
Facility number: 2, Name: heating , Cost/Hour: 2.0
There are 0 entries

 return total;
 public String toString( ) {
 StringBuffer temp = new StringBuffer();
 for (int i = 0; i < entries.size(); ++i) {
 temp.append( entries.get(i).toString() + "\n" );
 return temp.toString();
}

are you reffering to where i have public class
Facilitys extends Vector {
 private Vector entries;
 public Facilitys( ) {
 entries = new Vector();
That's correct. That's your problem.
i added the extends Vector, because without it i got

Putting a Class Object into a Vector

HI all
I need to put a class object into another classes vector, then be able to read it and retrieve data.
I can put the object into the vector but all i seem to be able to retrieve is data like Account@2343c2.
Is this some sort of tag? How do i get to the data?
thankz
joey

That's what you get when you print an object which does not have its own toString() method to do anything different - it picks up the Object class's toString method instead. For example:
System.out.println(new Object());It sounds like you're doing something like this:
Vector v = new Vector();
v.add(new Account(42));If you were to do the following, you would see that sort of output:
System.out.println(v.get(0));The appropriate way to do this would be something like the following:
   // Use a List reference instead of a Vector reference, and create
   // an ArrayList object in preference to a Vector object
   List list = new ArrayList();
   list.add(new Account(42));
   // Iterate through the list of accounts - use an
   // iterator because this prevents off-by-one errors
   // that arise with direct indexing.
   Iterator i = list.iterator();
   while(i.hasNext()) {
      // Cast the reference returned by the iterator from
      // Object to Account so that we can call account-specific
      // methods.
      Account current = (Account)i.next();
      // Call the method specific to the Account class (getBalance
      // is just an example that I made up).
      System.out.println(current.getBalance());
   }

Print out a Date in a format I want

Now if I print out a Date object, I will get something like "Sat Jan 01 00:00:00 CST 2005", but what I want is "1/1/2005". I tried to use the get methods to get the month, day, and year so that I can put them in a format I want. However, all the get methods have been deprecated. What will be a possible(maybe easy as well?) way to do it? Thanks.

Something like:
import java.util.Date;
import java.text.DateFormat;
import java.text.SimpleDateFormat;
public class Test {
 public static void main(String[] args) {
 DateFormat df = new SimpleDateFormat("d/M/yyyy");
 Date now = new Date();
 System.out.println(df.format(now));
 // new for Java 5.0 - almost the same format
 System.out.printf("%te/%<tm/%<tY%n", now);
}Note: If you're using Java 5.0, then you can use the new printf method for PrintWriters. However, this doesn't appear to have a formatting token for single digit months.

Unexpected behavior when creating Objects in a Vector

I have a situation where Objects in a Vector appear to be getting corrupted. The context is this: I obtain a ResultSet from a database, create a Vector of Strings for each row, and a Vector of these row vectors for the entire ResultSet. This is passed to a method where a POJO is created for each row. This method returns a Vector of these POJOs. In the Object constructor, a String array of initial values is created and also values are assigned to individual variables. Here is a snippet with the Object constructor
public class RefAuthorItem {
 private final String refKey;
 private String authorKey, firstName, lastName, itemKey;
 private int authorPosition;
 private boolean isDeleted, isNew;
 // Keep a copy of the original values
 private final String[] oldValues;
 * The constructor for the data object item.
 * @param dataVals a String array of the data values
 * @param isNewVal boolean true if this is a new item, false if it is
 * an existing item
 public RefAuthorItem(final String[] dataVals, final boolean isNewVal) {
 oldValues = dataVals;
 authorKey = dataVals[RefQueryBuilder.AUTH_NUM];
 firstName = dataVals[RefQueryBuilder.AUTH_FIRST_NAME];
 itemKey = dataVals[RefQueryBuilder.AUTH_PKEY];
 lastName = dataVals[RefQueryBuilder.AUTH_LAST_NAME];
 refKey = dataVals[RefQueryBuilder.AUTH_REF_FKEY];
 isNew = isNewVal;
 isDeleted = false;
 // the author position integer value is used to sort the display
 authorPosition =
 Integer.parseInt(dataVals[RefQueryBuilder.AUTH_POS]);
 }It seems the oldValues[] values should be identical to the corresponding individual variable values. When the following code is used to create the objects, they are not.
 final boolean isNew = isNewVal;
 Vector<RefAuthorItem> returnSet = new Vector<RefAuthorItem>();
 final String queryString = QueryBuilder
 .getRefQuery(keyString, tableName);
 Vector<Vector> dataSet = QueryDB.getResultSet(queryString);
 int columnTot = dataSet.firstElement().size();
 String[] itemVals = new String[columnTot];
 for (Iterator iter = dataSet.iterator(); iter.hasNext();) {
 Vector element = (Vector) iter.next();
 for (int i = 0; i < columnTot; i++) {
 itemVals[i] = (String) element.get(i);
 RefAuthorItem item = new RefAuthorItem(itemVals, isNew);
 returnSet.add(item);
 }What happens is this. I returned four rows from the database and the oldValues[] array for each of the four corresponding objects contains the data from the fourth row. However, when I retrieve the corresponding individual values (e.g., authorLastName) from the Object, it is correct. I checked the object values (oldValues versus individual values retrieved via getters) right after the object is created (the line: RefAuthorItem item = new RefAuthorItem(itemVals, isNew);) and get the correct results. Also, results are correct when the itemVals constructor is moved within the loop, as below
 int columnTot = dataSet.firstElement().size();
 for (Iterator iter = dataSet.iterator(); iter.hasNext();) {
 Vector element = (Vector) iter.next();
 String[] itemVals = new String[columnTot];
 for (int i = 0; i < columnTot; i++) {
 itemVals[i] = (String) element.get(i);
 RefAuthorItem item = new RefAuthorItem(itemVals, isNew);
 returnSet.add(item);
 } There is a problem here. Am I missing a subtle Java issue with instantiating the String array within the loop? Or is there a problem with Vectors? Thanks!

Dear ejp,
In the non-working code, I rewrite the itemVals[], create a new RefAuthorItem using the itemVals[] and repeat. I checked the RefAuthorItem immediately after it was created (with println()) and the oldValues and individual String values in the object are concordant. However, after the loop is completed (all RefAuthorItems are created and added to the Vector), the oldValues[] in the objects all have the values from the last row. The individual String variables in the object all have the correct value from the ResultSet row.

Print All Objects

On some of my Analyzer 7.2.5 reports, when I try to print with"Print All Objects", the radio button grays out andfreezes, and I need to kill it through Windows Task Manager. This has consistently happened to the multiple-object (6objects) reports, but it also inconsistently happened to reportswith 3 objects - it happens to some 3-object reports, but not theother 3-object reports. It seems to work fine with other reportswith 1 single object. Does anyone know the limit, which it shouldn't, of thefunction? Thanks.

want to read .rex File. The file contains combination of SQL code with table Names, Packages,Functions,There are three basic ways to read an external file.
You can use UTL_FILE and use standard/basic file I/O calls like fread() and fwrite() - common amongst most (if not all) programming languages.
You can define an external table for the file, and SQL*Load the contents of the file dynamically via a SQL SELECT statement.
You can load the file into a CLOB using DBMS_LOB and then process it - quite useful if the text file is XML as the XMLTYPE supports parsing a a CLOB containing XML.
I want to pick Each object name put in a separate file line by line.That in turn will need to use UTL_FILE to create an external file.
Keep in mind though that your in a database environment with PL/SQL. The very best place for data is inside the database in SQL tables. Not outside as external files. Thus you need to ask yourself whether dealing this way with external files is the best solution, and a robust and scalable one.
Granted, many times from the database side we need to deal with external files. The optimal method usually is to load that file's data into a database table as structured data - data that can be accessed via SQL and sorted, filtered, aggregated and analysed.
To provide a "file" as output - this should ideally be done directly from structured data (SQL tables). And can be done using HTTP (via a web enabled PL/SQL procedure that supplies the file content as a http Mime stream), using FTP (via UTL_TCP) or as a CLOB via a PL/SQL call interface. Using UTL_FILE is not necessarily the only option.

Printing graphics object in Landscape or portrait mode

Hello,
I have a graphics 2d object (a Tree Diagram) which is inside a JScrollPane,and the JSCrollPane is on a JPanel. it's length and width is more than one page. I am using a printable object to print the object. The task I need to do is,
(1). compress the width and length of the diagram, so that if can fit into one page, else split the diagram into pages, so that each part of it can be printed on different pages(page size A4) and then later those pages can be merged accordingly.
I am not able to find, how to split the graphic object(the tree diagram into pages), shoul d I try doing it using x and y co ordinate of the graphic object.

Internationalized Object data from database

Hi...
I like to know which concepts you use in web application in case you need dynamic object data internationalized. For static web pages I can use ResourceBoundles to get the data but I'm still searching for the ideal way to do this with Object data.
Let�s say you have a Product object which has a name and description in many different languages.
Preferably I like to do something like this
<c:out value="${product.name}"/>
to display the users preferred (session) language, and for the special case to force a language I might use something like this
<c:out value="${product.name}" locale="en_US"/>
Now my big question is how should I implement something like this. Should the product.getName() method include the logic to determine the users session to call something like product.getName(Locale)? Or should I implement a custom tag to handle cases like this?
What is your preferred way of doing this?
Thanks,
Gregor

But I don't know how.
Thanx in advance.

public static Vector prepareData(ResultSet rs)
     Object lValue=null;
     Vector returnedVector=new Vector();
     try
          Enumeration lEnum=null;
          rs.beforeFirst();
          while (!rs.isLast())
               lEnum=this.elements();
               Vector lLine=new Vector();
               int i=0;
               rs.next();
               while (lEnum.hasMoreElements())
                    lValue=rs.getObject(i);
                    lLine.add(lValue);
                    i++;
