I read and then copy files into a subfolder, and I need to rename the file names by adding the timestamp to the file name, for example like: "filename1_25.06.14_15:00:00.txt". How can I do that? Here is what I have:
public class Table_data {
static String files = null;
static List<O> l= new ArrayList<O>();
[Code]....
is it right what i tryed, because i get nothing with timestamp in file after running this.
I have a requirement to get the details of the files present in a directory on a server. I need to get the file names and timestamp. I have the below code to get the file names:
Connection conn = new OracleDriver().defaultConnection();
ArrayDescriptor arraydesc =
ArrayDescriptor.createDescriptor ("DIRLIST_T", conn);
File myDir = new File (dir);
String[] filesList = myDir.list();
ARRAY dirArray = new ARRAY(arraydesc, conn, filesList);
return dirArray;
But am not able to get the timestamp. How can I get the timestamp as well.

Disaster has struck some of ACME's redundant data centers. The administrators have managed to restore backups, but some data sets are still missing from some data centers. Fortunately, every data set can be found at least once in one or more of the data centers. However, before ACME can resume normal operations, it needs to ensure that each data center has a copy of every data set.Your goal is to ACME resume normal operations by writing a program to synchronize data sets between data centers using as few copies as possible.
The first line of input will contain an integer between 0 and 999999 inclusive, representing the number of data centers.Following that will be one line of input for each data center. Each line will contain an integer from 0 to 299 representing the number of data sets at that data center, followed by a space and space-separated list of data set ids currently present at that data center. Data set ids are each an integer between 1 and 999999, inclusive. Each line will be at most 999 characters long.Data set ids are not necessarily consecutive. The list of data sets will not be in any particular order.
Output:The program must output an optimal data set copy strategy to ensure that every data center has a copy of every data set. Output one line for every copy instruction.A copy instruction is of the form <data-set-id> <from> <to>, where <data-set-id> is the data set id, <from> is the index of the data center the data set will be copied from (1 = the first data center), and <to> is the index of the data center to copy the data set to.When there are no more copy instructions, the program must output the word "done" on a line by itself. There is often more than one correct output with minimal number of operations for a given input, and any output that satisfies the requirements is valid.
Example 1:
----------
Input:
4
3 1 3 4
3 1 2 3
2 1 3
3 1 4 2
One Possible Correct Output:
2 2 1
4 1 2
2 2 3
4 4 3
3 1 4
done
Example 2:
----------
Input:
2
2 1 2
2 2 1
Output:
done
how to do a deep copy of objects that contain references. I am specifically wanting to make a deep copy of a tree. Logically, each tree node contain references to its children nodes. Here is the basics of my node class
public class BSTNode implements Comparable, Serializable {
private String token;
private int count;
private BSTNode leftChild;
private BSTNode rightChild;
I know I must only be making a shallow copy because when I make a copy of tree1, called tree2, and edit tree1 the edits also appear on tree2. Here is my copy method within my BSTNode class
public BSTNode copy()
{
BSTNode obj = null;
try{
ByteArrayOutputStream bos = new ByteArrayOutputStream();
ObjectOutputStream out = new ObjectOutputStream(bos);
out.writeObject(this);
out.flush();
out.close();
[code]....
When I wish to copy the entire tree, I call that above copy method from my BSTree class using the methods below. (I have 2 methods because this is a homework assignment that requires a copy method that calls a preorder traversal method)
public BSTNode copy()
{
BSTNode copiedTreeRoot = new BSTNode();
return copyTree(copiedTreeRoot,root);
[code]....
And further along when I make changes to tree1, tree 2 also changes. I have no clue what I'm doing wrong. I believe it must be somewhere in how I return the new tree or something.I tried this edit to my copy method, but it made no difference.
public BSTNode copy() {
BSTNode obj = null;
try{
ByteArrayOutputStream bos = new ByteArrayOutputStream();
ObjectOutputStream out = new ObjectOutputStream(bos);
out.writeObject(this);
[code].....

View Replies View Relatedif there was a way to copy specific array info into a temp array with more concise code?
This is the code I have for instance:
tempList[0] = myCube.orange[2];
tempList[1] = myCube.orange[5];
tempList[2] = myCube.orange[8];
tempList[3] = myCube.blue[6];
tempList[4] = myCube.blue[7];
tempList[5] = myCube.blue[8];
But isn't there any way I could just condense it to be like:
tempList[0,1,2] = myCube.orange[2,5,8];
It would save me from 72 lines of code down to 24 if I could rock it all on one line.

I have a text file which contains to integer values I need to retrieve for each item (total of 56 items in the file). One is an item number, the other the weight ("Item: " + number + "Weight: " + weight). I am trying to build an array list that will add each set of data to it. I know that when I add the item array to the arraylist it is storing the array variable and not its contents, so is there a way to easily copy that data array to the array list?
ArrayList newInventory = new ArrayList();
int[] item = new int[2];
while(sc.hasNext()) {

I'm working on a simple site for my friend, and he asked me to link to his other site. I need to have the link to a specific search. For example, if I search for "Heathrow," I need to be able to link a button on the other site so that it can be clicked and directed to the search results on this page. Problem is that this is apparently all Java (which I know nothing of) and how to just copy a link to the results page.

Make 2 classes WrapperShallow and WrapperDeep.
Each class is simply a wrapper class to hold a private array variable. int [] a;
The default constructor for each class should initialize “a”.
Each class should have a toString() and equals().
Each class should have a setArray method that allows you to set the “a” variable.
WrapperShallow should have an invalid copy constructor.
[Code] ,....
Think about why shallow is wrong and deep is correct! What happens to the old “a” in the WrapperDeep copy
constructor? (think garbage collection)
Example Output:
