Putting Resultset objects in an Vector
Can anybody help me, I have to put all my results from the ResultSet in a Vector.
But I don't know how.
Thanx in advance.
for a vector of vector ....
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++;
returnedVector.add(lLine);
catch (SQLException e)
e.printStackTrace();
return returnedVector;

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
joeyThat'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());

How do I print out the attributes of objects from a Vector? Help !
Dear Java People,
I have created a video store with a video class.I created a vector to hold the videos and put 3 objects in the vector.
How do I print out the attributes of each object in the vector ?
Below is the driver and Video class
Thank you in advance

Vector, calling a method of an object in a Vector
hi and sorry for my poor english.
problem:
i have a Vector:
Vector objects = new Vector();i put some Objects in this Vector:
objects.addElement(new testObject());in the class testObejct() i've defined some methods like:
public method1() {
System.out.println("bla");
}how can i call that methods now by my Vector?
this doesn work :(
objects.lastElement().method1();thanx :)The vector method lastElement() returns an Object type so you need to cast the Object retrieved to the correct type before you can call one of it's methods.
Try something like
testObject to = (testObject)objects.lastElement();
to.method1();you can use instanceof to test if a class is a member of a particular type -
Send a ResultSet object via RMI - won't work.
Hi. I make a user interface to access MySQL database. The access to MySQL server is done from a remote location via RMI. The process to delete/update/create was succeed. The only problem is when I try to get(from the client computer) the ResultSet object, that come from invoking statementObject.executeQuery(myQuery) method, from the server Computer: it won't work. It said that the ResultSet object is not serialized(it is an interface). I need the ResultSet object for my client program since I will use it to set my AbstractTableModel class's object. Last goal is to put the AbstractTableModel object into the JTable constructor so I can see the result from a table.
Is anyone can help me? I can not return the ResultSet object to the client since it is not serialized.I use the following solution using List. As List is Serlizable I can throw it across the network using RMI... it is also of course easy to access.......
For users objects you need to throw across the network just simply make them implement Serializable
In your ORM class accessing the DB:
public List getSQLResults{
Resultset SQLResults = statement.executeQuery(SQLQuery);
Vector results = new Vector();
while (SQLResults.next()){
// create class object here if needed...
results.add(SQLResults.getStrinf("COL_NAME");
return results;In your GUI class..
JTable theTable = new JTable();
DefaultTableModel theModel = new DefaultTableModel();
theModel.addColumn(SOME_COLUMN);
try{
List resultsData = ORMClass.getSQLResults();
Iterator iterator = List.Iterator();
while(iterator.hasNext()){
iterator.next();
theTableModel.addRow(SOME_OBJECT);
theTable.setModel(theModel);
catch(Exception ex){
// exception rasied...... do something!!!

Why can't I add an Object[] to a Vector ? super Object[] ?
I don't understand why javac rejects these two statements:
Vector<? super Object[]> v= new Vector<Object[]>();
v.add(new Object[0]);cannot find symbol
symbol : method add(java.lang.Object[])
location: class java.util.Vector<capture of ? super java.lang.Object[]>
v.add(new Object[0]);
^
The type of v can only be one of these 4:
Vector<Object[]>, Vector<Object>, Vector<Serializable>, Vector<Cloneable>.
Therefore, I should always be allowed to add an Object[] to it, right?
The following example is very similar, but this one is accepted by javac.
Vector<? super Number> v= new Vector<Number>();
v.add(42);I didn't find a relevant difference to the first example, nor something in JLS3 that would forbid it. Is this a javac bug?There is a difference between legal and practical. Practical is a matter of opinion. I thought I should try the combinations to see which make sense.
I don't find it intuative that list.add(list.get(0)) should fail to compile.
While the definitions have a logic of their own, some are very hard to put it into english exactly what they really mean. This means finding a practical purpose for them even harder.
For example List<? super Object>
add(x) is legal for non-arrays
method(list) is illegal for method(List<Object>) but is legal for method(List<? super Object[]>)
public class A {

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. -
How to store a DB row (multiple columns) from ResultSet object to hm/ht
I am trying to store a DB row (which is containing ~150+ columns) from ResultSet Object to HashMap/Hashtable using the below code. But I wonder is, this not working and even do not get any error.
dataslotHashmap.put(rsmd.getColumnName(i+1),rs.getObject(i+1));
where "rsmd" ResultSetMetaData Object and "rs" is ResultSet Object.
Need advice pleaseCode snippet for reference:
rs=stmt.executeQuery("select * from ......
rsmd=rs.getMetaData();
rs.next();
int noc=rsmd.getColumnCount();
for(int i=0;i<noc;i+=1) {
dataslotHashmap.put(rsmd.getColumnName(i+1),rs.getObject(i+1)); -
can any one out there please tell me about how to retrive resultset object through RMI as resultset is not serializable? or should i have to do somthing other than RMI. (which actually i don't want to)
You cannot send a ResultSet object through RMI, as you
found out. But don't give up on RMI. Design your own
object to hold your data, then read through the result
set on the server and put the data into your new
custom object. Make sure that's serializable, then
you can send it through RMI. -

Using all types of resultset Objects i need a single program
i think all of u know that there are 8 types of resultset objects are there in jdbc technology i.e
# next() - moves the cursor forward one row. Returns true if the cursor is now positioned on a row and false if the cursor is positioned after the last row.
# previous() - moves the cursor backwards one row. Returns true if the cursor is now positioned on a row and false if the cursor is positioned before the first row.
# first() - moves the cursor to the first row in the ResultSet object. Returns true if the cursor is now positioned on the first row and false if the ResultSet object
does not contain any rows.
# last() - moves the cursor to the last row in the ResultSet object. Returns true if the cursor is now positioned on the last row and false if the ResultSet object
does not contain any rows.
# beforeFirst() - positions the cursor at the start of the ResultSet object, before the first row. If the ResultSet object does not contain any rows, this method has
no effect.
# afterLast() - positions the cursor at the end of the ResultSet object, after the last row. If the ResultSet object does not contain any rows, this method has no effect.
# relative(int rows) - moves the cursor relative to its current position.
# absolute(int n) - positions the cursor on the n-th row of the ResultSet object.
Using all these result set methods i need a sample program all these methods must be used in a single program itselfBalajiEnntech123 wrote:

They'd be especially wrong to think that the methods you mention are "types of resultset objects". -
Scrollable/Read_only ResultSet objects

Thank you.I don't believe the Oracle driver allows for
read/only. I'll take a look at the Oracle website,
and see if I can verify that.
JoelSorry, I was wrong on this. From the Oracle JDBC documentation, it states that CONCUR_READ_ONLY is valid for the Oracle 8 and Oracle 9 drivers. Are you using classes12.zip or classes12.jar for your Oracle libraries? -

Can i open more than one Resultset object
hi in my program i have to retrive data from three table and the data from three
table i have to use in another one
i wanna know that can we open more than one ResultSet object within one
try{
}catch{] block ( i means ResultSet rs = st.excuteQuery(query) more than one time for different -different tables)
or there is any other way to do thisYou can only have one active result set per statement at a time.
Depending on the driver you are using you might be able to have more than one active statement (and result set) on one connection. Or not.
Try catch has nothing to do with that.
If you are nesting result sets then it is likely you should be using a join (SQL) which would then only require one result set. -
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.

// System.out.println(entries.firstElement() );
System.out.println("printing out entries");
System.out.println(entries);

System.out.println("There are "+entries.size()+" entries");

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
