Ask User To Store 10 Numbers In Array - Print In Order Entered And Reverse

Apr 15, 2014

Write a Java program that asks the user to store 10 numbers in an array. You should then print the array in the order entered and then print in reverse order. However, instead of putting all the information in the main, you should use a class called PrintIt. The PrintIt class should have an instance variable that is an array to hold the numbers. You should have a method that will print the array in the order entered. You will also need a method to print in reverse oder. Then create a tester class that asks the user to enter 10 numbers and puts them in an array.

So far I've got this.

public class printIt {
int i;
int [] numArr = new int [10];
public printIt () {
i = -1;

[Code] .....

Output:

Enter a number:

8
34

Forward:

8
34

Reverse:

34
8

end

what i want as an number is being able to print out 10 numbers but this only lets me do two numbers. Why is that so?

Store String Input In Array And Print In Reverse Order

Apr 5, 2014

I have a college question ask me to write a class StringRevert which does the following:

-prompting user for an interger n
-creating an array of n string
-repeatedly read character string from user input and store them in the array until end of array is reached or user input -quit(quit should not saved in array)
-print the string from array in reverse order, from last enter to first enter.
-assume user always supplie correct input

This is what I've done so far but how to get it working.

import java.util.Scanner;
public class StringRevert {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.println("enter value of n: ");
int n1 = in.nextInt();

Java Reverse Order Using Pointers?

Oct 9, 2014

This is what I have to do:Write a program that takes a string of someone's name and prints it out last name first. Your program must use pointers, not array subscripts. You may use the available string manipulation functions if you find an opportunity.

Example:

"George Washington"
"Washington, George"

I am not sure how to reverse the name, I have been looking in my textbook and online and cannot figure it out. This is what I have put together so far, it does not run. At the end it says unnecessary return value.

import java.util.*;
import java.util.Scanner;
public class Test {
public static void main ( String [] args ) {
Scanner sc = new Scanner(System.in); 
System.out.print("Enter name: ");
String name = sc.nextLine(); 
String lastname = "";
String firstname = "";
for(int i = 0; i < name.length(); i++) {
if(name.charAt(i) == ' ')

Reverse Double Linked List In Java - Descending Order

Sep 12, 2014

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.

Display Contents Of File In Reverse Order - Output To Console

Jun 24, 2014

Create a class that allows the user to select a file and output the contents of the file to the console. Recommend using a text file to display, java files are text files. You may want to put this code in a method to allow you to complete the remainder of this assignment without overwriting your code.

- You should ask the user to enter the full path to your file to make certain you are processing the correct file.

- Modify your code/add a method to display the contents of the file in reverse order. You do not need to reverse the characters on each line but simply output the lines of the file in reverse order.

Hint: read the content of the file into an ArrayList and then traverse the ArrayList.

this is what i go so far.

package classActivity;

import java.io.File;
import java.io.FileNotFoundException;
import java.io.PrintWriter;
import java.util.ArrayList;
import java.util.Collections;
import java.util.Scanner;
public class Select
{
public static String enterFilePath()

[Code] ....

Program That Use Array To Store 10 Numbers

Oct 16, 2014

i'm trying to write a program that uses an array to store 10 numbers. The numbers should be randomly generated ( Math.random() ), and they should be between 1 and 100 ( 1 and 100 inclusive ). The program should produce an output like the one below:

Element 1 = 23 ( Odd )
Element 2 = 15 ( Odd )
Element 3 = 32 ( Even )
Element 4 - 10 ( Even )
Element 5 - 99 ( Odd )
Element 6 - 1 ( Odd )

[Code]...

I have written code for this but its only showing me 0's after first number can you check whats wrong with my code. my code is.

class even/odd{
public static void main(String[]args){
int y=0;
int z=0;
int[] array= new int[11];
for(int x=1; x <array.length ; x++){
array[x]= (int) (Math.random()* 100);

Create Program That Draws Random Numbers And Stores Them In Array

Oct 1, 2014

Is my code right for this pseudocode:

<Declaration of the array for storing random integers and other necessary variables and / or constants. >

private int numbers;
private int max;
private int[] integer;
private Random generator;
public integer ( int n, int m )

[code]....

I need to create a program that draws random numbers and stores them in an array. How many numbers to be drawn is dependent on the array length, which is a parameter in the class constructor. (The entire array to be filled!) The program shall, however, just save the figures are not drawn already. (Ie, the array must contain only one instance of each numeral.) All figures drawn should be in the range of 100 to 1000, both limits included. These limits are defined as named constants. When all the numbers are generated and stored in the array, the program should find the largest, smallest and average value of the numbers in the array. In addition, it should find the value closest gjennomnstittetsverdien.

Generate 100 Numbers Using Arrays - Sort Even Numbers Into Separate Array And Display Both

Apr 24, 2014

I've just written a program that generates 100 numbers that range from 0 ~ 25 using arrays, the program calls another method that sorts the even numbers into a separate array and returns the array. I need it to display both arrays, however, when I run my program, the numbers of both arrays are mixed together, and I'm not sure how to separate them.

[ public class Array1

public static void main(String[] args)

{
array[i] = (int) (Math.random() * 26);

Add Program In Order To Dice To Roll

May 8, 2014

what code I should add to my program in order to get these dice to roll. The program, according to my teacher, is CORRECT so far, so I'm not going to change anything. I just need to know how to roll the 2 dice I added in. I just want to get it done. No math.Random. The direction is: Roll each of the Dice by invoking the roll method on each Dice in the array.

My code:

//Dice.java
package homework3;
import java.util.Random;
public class Dice {
private int numberShowing;
private int numberOfSides;
private static final Random randomNumber = new Random();

Sorting Array In Alphabetical Order

Feb 3, 2015

I am trying to sort an array that I have by alphabetical order but I am having problems. Firstly the code that I have used to sort the array may not even do what I need but havn't got far enough to test it yet so go easy on me . I have read in some places when searching how to do this that I would have to create my own bubble sort in order to achieve this but I was hoping that Java had a built in sort method/function. Secondly I lack the knowledge in java to be able to assign an existing array or even a variable to the newly sorted array as I need the unsorted version with the original name and the newly sorted version as another.

code (This is not all of the code, I decided to include only what I thought was relevant):

import java.util.Arrays;
public class Sentence {
private String words[];
public Sentence(String[] words) { this.words = words; }
@Override
public String toString() {
return "Sentence{" +
"words=" + Arrays.toString(words) +

[Code] ....

Is it possible to shorten the sort function to just this?

public String sorted() {
return Arrays.sort(words);
}

Copying All Elements In Array A To B Sorted In Ascending Order

Apr 7, 2014

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)
at Quest30.CopyAndSortArray.main(CopyAndSortArray.jav a:16)
