Converting Descending To Ascending
May 6, 2014
I have not a clue how to convert this to ascending from its current descending....
class Node
{
private int iData; // data item (key)
//-------------------------------------------------------------
public Node(int key) // constructor
{ iData = key; }
//-------------------------------------------------------------
public int getKey()
{ return iData; }
[Code] .....

I am sorting an array in ascending and descending order. I am using the nethods in Arrays as below
Arrays.sort(myArray)
I want to print both input and output array in sysout.
Object[] ipArray = [45,8,32,41,11,7];
Object[] opArray;
Object mArray = ipArray;
Arrays.sort(mArray); This is changing the ipArray too ?
How can I get my input array unmodified ?

I wrote displayAscending() and displayDescending() methods to this double linked list and it is not working at all. Logically it seems fine to me. I positioned the head in the beginning in the ascending method; created a variable named data1 as an auxiliar variable so it can store the values that are going to be moved; and moved the values. Same thing for the descending method but instead of the head I put the tail and move left the list, instead of right.
import java.util.*;
class node {
int data;
node left;
node right;
node(int d, node l, node r) {
data = d;

I am trying to make a programm that reads a word and display if the letters are in ascending order or not in ascending order(All kind of letters..capitals..etc). I have made a code but its not 100% correct.
My code:
class Main
{
public static void main(String args[])
{
System.out.print( "#Enter text : " );
String text = BIO.getString();
while ( ! text.equals( "END" ) )
{
if (text.equals("END"))

I am trying to find the longest descending sequence without arrays. So 65124976231 would output 9762.
import java.util.*;
public class HelloWorld {
public static void main(String[] args){
String num = "";
int longestLen = 0;
int currLen = 0;
String max = "";
[Code]...
I keep getting: The longest descending sequence is: 6512 In an infinite loop.

I am trying to create a java program to sort an array in ascending and descending order. Here is the program I created :
import java.util.Arrays;
import java.util.Collections;
public class ArraySort
{
public static void main(String [] args) {
int [] num = {5,9,1,65,7,8,9};
Arrays.sort(num);
[Code]...
BUT I GET THE FOLLOWING EROOR ON COMPILATION
ArraySort.java:12: error: no suitable method found for reverseOrder(int[])
Arrays.sort(num,Collections.reverseOrder(num));
^
method Collections.<T#1>reverseOrder(Comparator<T#1>) is not applicable
[Code] .....
What's wrong with my program?

I am working on descending after I assign values. And everything is sorted, but one value. I don't know why always I get one value is not sorted.
public class SeunghunJunHw6 {
public static void main(String[] args){
double[] randomArray = new double[9];
//assign random double values between 0 to 100 but exclude 100
for(int i = 0; i<randomArray.length;i++){
randomArray[i] = Math.random()*100;

I have the following double linked list and I'm supposed to order it descending (reverse) using the printInReverse() method; since the list orders itself ascending when the numbers are added, how could I order it descending in this method? Here's the code without implementing descending/reversing methods:
package test;
import java.util.Scanner;
public class MyList {
private Scanner userInput;
private Integer selectedOption;
private MyListElement firstElement = null;
private boolean exitRequested = false;
[Code] ....
I tried to declare a previousElement variable but I didn't figure out how I'd do that.

I had to make a program that allowed the user to enter the number of students and the students names and grades and then print out the name with the grade in descending order. right now I only have it where it prints the names out in descending order. how do I get it the print out with the grade?
Here is my code
import java.util.*;
public class Grades {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.print("Enter the number of students: ");
int numofstudents = input.nextInt();

I'm not looking for answers, well I am.. but not just straight given to me. I'm trying to learn but for this program I'm not even sure where to start. One step looks like this:
O *******
/| * *
/ * *
************
It must increase by a constant named STEPS. They ascend from left and go up right.
I'm just gonna start asking some questions I guess. Before I do anything I wanted to know whether I should have the stick man on the step drawn out with print and println statements or try to have him drawn with a loop as well? I'm not sure if my teacher wants everything drawn by characters with loops for each character, or if I can do print statements and draw the stick figure plus some stars and have a loop for multiple characters at once.

I am making a program to read data from excel files and store them in tables by their IDs. I have managed to read all the data from excel files as a string and store them in a table. But my project is to store them in table by ascending IDs. I have created the comparator in another class but when i call it in the main class nothing happened. The data that I have to store is like the below:
ID Name Salary
50 christine 2349000
43 paulina 1245874
54 laura 4587894
23 efi 3456457
43 jim 4512878
The codes are below:
import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.util.ArrayList;
import java.util.Collections;
import java.util.Comparator;

I am writing a program that grab user input number which represent beats per minute separated by commas. It then parses the numbers and reorders them from smallest to largest and then outputs the average, medium, maximum and minimum number all in separate lines. I am having trouble getting the array to sort the input from smallest to largest. It is currently only working for 3 numbers inputted. Anything more will not reorder it.

How do u copy all the elements in an array eg A into another array eg B? This is the question:
An array A contains integers that first increase in value and then decrease in value,
For example, 17 24 31 39 44 49 36 29 20 18 13
It is unknown at which point the numbers start to decrease. Write efficient code to code to copy the numbers in A to another array B so that B is sorted in ascending order. Your code must take advantage of the way the numbers are arranged in A.
This is my program:
This is the error message:
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException
at java.lang.System.arraycopy(Native Method)

I couldn't where the problem with this code. The question is : (Write a program that reads in nine integers and sorts the value in the ascending order. Next, the program restores the sorted integers in a 3 x 3 two-dimensional array and display the integers as shown in the result.) And this how i did it:
package test1;
import java.io.*;
import java.util.*;
public class test1{
public static void main(String[] args){
int[] hold = new int [9];
Scanner sc = new Scanner(System.in);
System.out.print("Enter 9 integers, press <Enter> after each");
{
for (int i = 0; i < hold.length; i++);

I'm converting from ASP to Java for a legacy site. I believe the first part of the if statement is right but I'm having an issue within the else staetment. I'm getting date is undefined, I've tried using getYear and getDate but have not been successful.
ASP:
If Request("action") = "results" Then
aMonth = Request("selMonth")
aDate = cint(Request("selDate"))
aYear = cint(Request("selYear"))
Else
aMonth = UCase(MonthName(Month(Date()),true))
aDate = Day(DateAdd("d",-1,date()))
aYear = Year(Date())

When I read the result in Notepad++ with HEX-Editor plugin, I find attached image which is different from above String, there is one additional c2 and I am quite confused.
Java Code:
public static void main(String[] args) throws IOException {
Test strToHex = new Test();
File file = new File("D:/filename");
// if file doesnt exists, then create it
if (!file.exists()) {
file.createNewFile();

I was reading about the char data type in Java. I know that an unsigned 16 bit integer is used to represent a char. So we can write the assignments below:
char a = 65; // a will get the value 'A'
But the limit of the char value is 65535.
So I've tried out a few things with char and trying to understand them but I'm not sure how they work.
char a =(char) 70000;
char b = (char) -1;
In the first case I thought that 70000 % 65535 would happen internally and the unicode character present at that location would get stored in 'a' but if I do that I get the answer of 70000 % 65535 as 4465. But when I display 'a' it shows me the output as '?'. Clearly '?' isn't at 4465.
In the second case I have no clue what's happening but somehow when I display 'b' it shows me '?' again.
