I have an requirement of splitting a Date-Time String i.e. 2013/07/26 07:05:36 As you observe the above string has Date and Time with space in between them.
Now I want just want split the string not by delimiter but by length i.e. after 10th place and then assign it to 2 variable i.e. Date <----2013/07/26 and Time <---07:05:36 separately.
write the algorithms of the following problems.
1. Write an algorithm that asks the user for your birth date and the current date and displays how many days has passed since then (remember that April, June, September and November has 30 days, February has 29 on leap years, and the rest 31)
2. Write an algorithm that asks the user a number (save it as N) and displays the N term of the Fibonnacci series (take it as 1, 1, 2, 3, 5 ...)

View Replies View RelatedGiven a Date such as this sampleDate (120, 08, 02), does SimpleDateFormat transform this given sampleDate using (sampleDate.get(Calendar.DATE)) ?
Issue is that without the SimpleDateFormat the days are outputting correctly but starting with 1,2,3,4 etc and when I apply the SimpleDateFormat to the above Date I only get 01,01,01 etc...
I am looking for 01,02,03 etc...

View Replies View RelatedGiven the case I have an object which is assigned only once. What is the difference in doing:
public class MyClass {
private MyObj obj = new MyObj("Hello world");
private MyClass(){}
//...
}
and
public class MyClass {
private MyObj obj;
private MyClass(){
obj = new MyObj("Hello world");

Is there a difference in performance or usability? (Given also the case there are no static calls expected) ....
The term "Local variable" is related to scope. That is a local variable is one which is defined in a certain block of code, and its scope is confined inside that block of code.And a "Member variable" is simple an instance variable.
I read in a discussion forum that when local variables are declared (example code below), their name reservation takes place in memory but they are not automatically initialized to anything. On the other hand, when member variables are declared, they are automatically initialized to null by default.
Java Code: public void myFunction () {
int [] myInt; // A local, member variable (because "static" keyword is not there) declared
} mh_sh_highlight_all('java');
So it seems that they are comparing local variables and member variables. While I think a member variable can also be be local in a block of code, isn't it?
Given a reference variable : Car c1 = new Car();
when we create another variable and set it equal to the first : Car c2 = c1;
we're pointing c2 at the same car object that c1 points to (as opposed to pointing c2 at c1, which in turn points at the car). So if we have code like,
Car c1 = new Car();
Car[] cA = {c1, c1, c1, c1};
are we doing the same? Are we creating four *new* reference variables, each of which points at the same car (again as opposed to pointing them at c1 itself)? I think so, but want to make sure I'm understanding this correctly.
I have a JFrame jf and JPanel jp on it. jp has five TextFields named cel1, cel2.. cel5. I wish to construct a String Cel + for loop index and run a for loop to reset the values of all the text fields using a single statement such as cel1.SetText("abc"). Similar things can be done in foxfro. How does one do it in java?
View Replies View RelatedI don't really get the concept of how I "insert" an item into an array. I get a cannot find symbol error when I try to. I think its because I'm losing focus. What sort of code would "insert" an item into an array? I just want a goal of conceptually how I would do it.
Anyways, here are the instructions for the exercise:
Write a new class method, insert, for the Item class that takes three arguments - an Item[] array, an Item newItem, and an int k - and inserts newItem into array at index k, discarding the last item of the array (that is, the item originally at index array.length - 1).
Here is the uneditable code:
public class Item {
private int myN;
public Item( int n ) {
myN = n;
}
public String toString()
[Code] ....
I get a cannot find symbol error, but I thought I was doing as I was supposed to. I thought you had to have an ArrayList to be able to insert or delete an item from an array. How can you take a primitive object, like an array, and insert something into it. My idea of it was a[i] would be replaced with a[i + 1]. I know I'm getting this concept wrong because that's what I tried to do.
We have this piece of code and we must make a search for a key. if the key exist it returns true if not false. Plus we must insert a key in the class. If it is already in there we say hey its already in and we don t put it again...

My task is to implement a B-Tree data structure in Java using no libraries.
My current problem is inserting when the root is full, thus the middle key goes to root.keys[0] and then it get the left and right side which are new Nodes separating and inserting their keys. My problem is that for some reason there is a random second number when in the root and secondly my boolean leaf is always false meaning it never detects that the Tree is deeper than root.
The coding makes sense to me and I have tried printing everywhere but still can't seem to find the problem.
public class BTree {
/*
1. You may not modify the public interface of this class. You may however add any additional methods and/or field which you may require to aid you in the completion of this assignment.
2. You will have to design and implement a Node class. The BTree should house Integer objects.
3. You will notice that there are some overloaded methods, some of which work for Integer objects and some with primitive type int. You have to find a way to implement the methods to work with both types.
*/
class BTreeNode {
boolean leaf = true;
int numKeys = 1;
int mOrder;
Integer keys[];

I am trying to add a while loop into my switch statement. If you run the program, it will ask to enter the class grade (9,10,11, or 12). If you insert 5, it will say to try again. But, if you enter a wrong number twice, it will continue on to the next part of the program, which is asking how many students are in the class. Therefore, I believe a while loop would work, but it is not working at all. The program still runs, just doesn't fix the error. The program is below:
import java.util.Scanner;
public class stephProject {
public static void main(String[] args) {
//call method
