public static void main(String args[])
{
System.out.print( "#Enter text : " );
String text = BIO.getString();
while ( ! text.equals( "END" ) )

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 ?
tfrreee i want to display given series in ascending order in java prog here is an error : E:Javajdkin>java ascend 505671Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 7 at ascend.main(ascend.java:9)
Java Code:
class ascend
{
public static void main (String args[])
{
int s[]={ 50,71,81,21,7};
int i;
for(i=0;i<=s.length;i++)
[Code]...
For example, if i am given 9864
Imust output 4689
Without use of arrays.
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

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 doing an exercise we're you're supposed to sort strings in alphabetical order, without importing anything , not using the Arrays.sort() method.
I think I got the method down partially right, or it is on the right track, but it is completely not being applied to my answer. All it prints out in the console is the actual String array twice, without sorting anything.
public class arrayofstrings {
public static void sort(String[] a) {
String temp= "";
int min;
int i= 0;
for (int j=0; j<a.length-1; j++) {

View Replies View RelatedI am trying to sort the 5 cards in decreasing order and this is exactly what my professor gave us but it has errors.
int pos;
int max;
for (pos = 0; pos < hand.length; pos++){
max = pos;

Line 6 has an error with the < operator.
Line 11&13 says cannot convert from card to Int.
This method is passing in Card[] hand
One of the random number generators in Java extract the higher-order bits of the random number in order to get a longer period.
I'm not sure if I understand how this is done. Suppose that the random number r = 0000 1100 1000 1101. If we extract the 16 most significant bits from r; is the new number r = 0000 1100 or r = 0000 1100 0000 0000?
Any link to the accurate explanation of binary trees in java?

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

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;

If this method returns the lowest score, how do I return the 2 lowest scores.
For example If I input 1, 2, 3, 4, 5 this code will return 1.
How do i return the two lowest scores, for example if I input 1, 2, 3, 4, 5, I want to return 1, 2
public double getLowestScore() {
smallest = testScores[0];
double sum = 0.0;
double total = 0.0;
double Average = 0.0;

So for this project I'm going to take in some quiz scores, then eventually get the total number, the range, the mean, and others... Here's the instructions for the two methods I need to create but am completely stuck on:
2. public boolean inputData(Scanner in)
2.1.takes in a Scanner object passed in from main()
2.2. asks the user for a number in the range of 0 through 100.
2.3.It must read a number into an integer variable unless a non-number value is entered, in which case the method will return false. You may use try/catch or an if statement for this.
2.4.If the datum/score seems acceptable, the addGrade method must be called.
2.5.If addGrade returns false, then inputData should throw an IllegalArgumentException or return false
Otherwise, inputData should return true. See section 11.4 for exceptions.
3. public boolean addGrade
3.1.takes in an integer grade. If grade is not in the range of 0 through 100 the method should return false.
Otherwise, it should appropriately change the values of numberOfQuizzes, highValue, lowValue,
3.2.totalQuizScore , sumOfSquares (used in variance calculation), and add one to the count of the proper variable for A's, B's, C's, D's or F's. The method should then call calculate and return true
Now I have done very little with booleans in class at all, so this is all very confusing for me. I've tried to do a lot of research on my own and so far I came up with the following for the two methods above:
public boolean inputData()
{
int score = 0;
System.out.println("Please enter values, Q to quit:");
Scanner in = new Scanner(System.in);
while (in.hasNextInt())
[Code] ....
Honestly I'm not really sure what I'm doing wrong at all, and I have done a lot of research but can't really find anything too similar to what the instructions want so I'm not sure what's right/wrong.
I am trying to figure out how to report the high and low scores with names from a file. The format is like:
6352 J@me$$
663843 BOBBBB1
etc...
This is my code so far.

Design and write a Java program that will generate a set of test scores between 0-100, inconclusive. The exact umber of scores is determined either randomly or by the user input. There should be a minimum of 5 test scores. The program calculates the average of all test score in this data set. Then it asks the user how many scores are to be dropped and drops that number of low scores. The average is recalculated.
Output of this program:
The original test scores printed in rows of 10 scores
The average before low scores are dropped
The number of low scores to be dropped
The list of low scores dropped
The new average
I'm writing a program that is about rolling "dice" and getting the scores to add up to 100. There are two players in the game and each must take turns rolling dice choosing whether or not to keep rolling dice and accumulating more points during their turn while risking their points being lost by rolling a 1 or to add their turn points to their total points. The question I have is how would I exit the do while loop if the player chooses to add their turn score, thus adding their score and ending their turn?
Here is the coding so far.
Java Code:
import java.util.Scanner;
import java.util.Random;
public class Pig
{
public static void main(String[] args)
{
int die; int userTotalScore; int userTurnScore; int compTotalScore; int compTurnScore;

Alright, so, for my CS project, we're supposed to list diving scores. However, there are four sections (which I've made in the code) and each section has 9 scores. Of those nice scores, the highest and lowest must be eliminated and then the total needs to be figured out. We're supposed to be using arrays for this...
import java.util.Scanner;
import java.io.File;
import java.io.FileNotFoundException;
public class Diving {
public static final int MAX_DIVES = 51;
