View Replies View RelatedSplitting Date String By Date And Time And Assigning It To 2 Variables?
Jul 17, 2014I 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.
Algorithm That Asks User For Birth Date And Current Date
Sep 29, 2014write 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 RelatedTransform Simple Date Format - Get Calendar Date
Apr 4, 2015Given 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 RelatedWhat Does Setting Object Equal To Another Do
Mar 5, 2014I've seen this done in code:
For example:
Java Code: BufferedImageOp op = new ConvolveOp() mh_sh_highlight_all('java');
What does this mean? Is it creating an object of convolveOP for the BufferedImage class?
What does it mean when you set an object from one class equal to another?
How To Equal Compressed Data
Sep 29, 2014I have an object that may contain several other objects (sub-object) and will compress those sub-objects.
My question is generally what is a good way to compare two objects, as described above, if they are equal (e.g. through equals() function)?
Intuitively there are two ways I can think of: 1. Compare each compressed bit
The disadvantage I think is it's not efficient if the object is very big. For instance, when it holds several gigabytes data, it may took too long for just comparing each bit.
2. Hash the sub-object before compressing it, and then compare all hashed values. This problem is I am not very sure if hashing is a good way to compare objects. And if collision may be the problem?
Equal Values In Two Columns For Every Row In Jtable?
Feb 5, 2014I have a JScrollPane with two coulmns. In the first column I have an image pane JTable, and in the second a list with names of sections. This second column I try to divide in two columns, one (the second column) to display the names of the sections (each row contains one name), and in the other column (the third) I want to show some values for every section in the row respectively. But, instead of displaying the desired values in the third column, I get the same names of the sections as in the second column. Here is a part of the code I have:
private Vector<Section>daten = new Vector<Section>(0); //These are the values for the first column in the Jscroll
private String[] header = {"Section","calcGYR"}; // These are the values for the second and third column (in this case the header for the both columns
public TrafficObserveModel(Vector<Section> daten) {
setData(daten);
[code]....
But I don't know how to modify the methods in order to render the desired integer values in the third column.
How Many Numbers In Array Have Value Greater Than Or Equal To 100
Sep 10, 2014I have an assignment that wants me to write a Java function based on induction to determine how many numbers in an array have a value greater than, or equal to, 100.
I have started with:
Java Code:
int recurseHundred (int [] A, int n) {
//n is the number of elements in the array.
//Base case:
if (n == 1 && n >= 100) return A[0];
//Recurse
int num = recurseHundred(A, n-1);
if (n-1 >= 100) return A[n-1];
else return num;
} mh_sh_highlight_all('java');
I don't think this actually does the trick.
Override Equal And Hashcode Method
Jul 7, 2014I read this tutorial about overriding equal and hashcode method. [URL] ....
I understand how to override equal method, by overriding it, We can custom our compare. I also understand How to override hashcode, To make custom hash.
But still I can not understand why we do it? why if equal method override, we must override hashcode method too?If we don't what is the problem?
To honor the above contract we should always override hashCode() method whenever we override equals() method. If not, what will happen? If we use hashtables in our application, it will not behave as expected. As the hashCode is used in determining the equality of values stored, it will not return the right corresponding value for a key.
Is it the right reason in order to override:
Because when we customize equal method so it focus on special variables,We must change the hash code too in order to match with it, so hashcode also focus on those special variable.
How To Test For Array Length Equal To Zero
Mar 15, 2015I am working on an assignment covering exception handling and am stuck on part of the assignment. How can you test for array length = 0?
When I try something like: if (array.length == 0) on a null array, naturally I get a NullPointerException. I would try something like if (array != null) but both array length of 0 and null array are supposed to throw different expressions.

View Replies View RelatedHow To Modify Text So That It Doesn't Contain Two Equal Numbers

Comparing Two Array Lists - Output If They Are Equal Or Not
Nov 21, 2014I need comparing two array lists. For this program i am comparing 2 array lists. The list is integers entered by the user the second is random generated numbers. So far in my program i am able to compare the 2 arrays together and output if they are equal or not however i need the program to output even if atleast one if the integers match,
EXAMPLE list one: 1, 2 ,3 ,4, 5. LIST TWO: 1, 3, 3, 3, 3.
Since the first number matches i want it to out put there is one match, so on and so forth with if there are 3 or 4 matching integers. here is my code so far.
public static void main(String[] args)
{
final int NbrsEntered = 5; //Number of guessed numbers entered
final int LOTTOnbr = 5;
int[] numbers = new int[NbrsEntered];
int[] randomNum = new int[LOTTOnbr];
//int[] TestArrayOne = { 1, 2, 3, 4, 5 };
//int[] TestArrayTwo = { 1, 2, 3, 3, 5 };
boolean arraysEqual = true;
int index = 0;

View Replies View RelatedArray Of Scores - Return True If Each Score Is Equal Or Greater Than One Before
Mar 8, 2014Given an array of scores, return true if each score is equal or greater than the one before. The array will be length 2 or more.
scoresIncreasing({1, 3, 4}) → true
scoresIncreasing({1, 3, 2}) → false
scoresIncreasing({1, 1, 4}) → true
Java Code:
public boolean scoresIncreasing(int[] scores)
{
for (int i = 0; i< scores.length-1; i++) {
if (scores[i] < scores[i+1] || scores[i] == scores [i+1]) {
return true;
} else {
return false;
}
}
return false;
}
Unsure what the problem is, it will always return True for some reason...
Convert String To Two Dimensional Char And Output Is Equal To Matrix
Jan 6, 2014I have written the code:
Java Code:

Scanner input = new Scanner(System.in);
System.out.print("Type your text: ");
String text = input.nextLine();
int counter = text.length();
if(text.length()> 16)
[Code] ....
And input is: abcdefghijklm
output is:
Java Code:
a b c d
e f g h
i j k l
m x x x mh_sh_highlight_all('java');
So all i want is, if i type: abcdefghijklm
I want this output:
Java Code:
a e i m
b f j x
c g k x
d h l x mh_sh_highlight_all('java');
Reference Variable - Create Another Variable And Set It Equal To First
Jan 11, 2015Given 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.
