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();
String[] n = new String[n1];

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?

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()

Print ASCII Image Using Nested For Loops - Reverse Iteration?

Oct 6, 2014

I'm writing a program to print an ASCII image using nested for loops. The output is a rocket ship that looks like this.

/**
//**
///**
////**\
/////**\
+=*=*=*=*=*=*+
|../..../..|
|.//..//.|
|//////|
|//////|
|.//..//.|
|../..../..|
+=*=*=*=*=*=*+
|//////|
|.//..//.|
|../..../..|
|../..../..|
|.//..//.|
|//////|
+=*=*=*=*=*=*+
/**
//**
///**
////**\
/////**\

I'm having problems with the mid section of the rocket, specifically the bottom part of the mid section:

|../..../..|
|.//..//.|
|//////|

I'm having difficulty writing the for loop to correctly print the dots. You're supposed to incorporate a constant which allows you to adjust the size of the overall figure. The loop doesn't work when I adjust the size, only when the value of HEIGHT is 3. The loop, however, for some reason works with the top part of the mid section.

This is the for loop for the top section.

for (int dots = 1; dots <= -1 * line + 1 * HEIGHT; dots++) {
System.out.print(".");
}

This is the for loop for the bottom section.

for (int dots = -1 * line + 1 * HEIGHT; dots <= 1; dots++) {
System.out.print(".");
}

Usually reversing the iteration of the loop just requires flipping the conditions, right? But it didn't work this time for some reason. Why this doesn't work? I can post the code to my entire program for compiling.

Multidimensional Array - Print Out 5 Names With Gender Type

Apr 19, 2013

I just started in java programming and into Arrays multidimensional. I started a simple 2 dimensional array with 5 names with genders. I 'm having issues because it does not want to print out the names with correct genders Male/ Female. The simple program should print out the 5 names with gender type.

example:

Jack - Male
Sally - Female
Dave - Male
Sue - Female
Brian - Male

Here is what I came up with so far:

public class Multiname
{
     public static void main(String[] args)
     {
          //String[][] multiname;
          String [][] multiname =

[Code] .....

This is the result:

multiname : Jack
multiname : sally
multiname : Dave
multiname : Brian
multiname : Sue

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 1

Print Statement Not Printing In Order To Call A Method From Another Class

Mar 17, 2015

I have wrote the necessary program for the class which was : Modify the customer class to include changeStreet(), changeState(), and changeZip methods. Modify the account class to include a changeAddress() method that has street city and zip parameters. Modify the Bank application to test the changeAddress method.

The problem arose when I went to test it. For some reason when it asks "Would you like to modify your account information? (y/n)" it will not allow the user to input anything and thus test the class. Here is my code

Class Customer
import java.util.*;
import java.io.*;
public class Customer {
private String firstName, lastName, street, city,state, zip;

Invoke Some Methods In For Loop In Order To Print Some Info Stored In A List

Apr 28, 2014

I am trying to invoke some methods in a for loop in order to print some info stored in a List. But for some reason, compiler pops a message saying "cannot find symbol - method getEmpID(). You are using a symbol here (a name for a variable, method or class) that has not been declared in any visible scope." But I am pretty sure that method getEmpID (as also getName(), getAfm(), and payment() ) have been declared as public.

Note: My List contains objects of different type (SalariedEmployee, HourlyEmployee). I hope this is not the factor causing this problem.

Java Code:

import java.util.*;
abstract class Employee{
private String name = "";
private String afm = "";
private long EmpID;
static long count=0;

Letter Count - Ignore All Numbers Or Punctuation Marks

Nov 13, 2014

I'm trying to make a program that will count each letter like if I put the word

e-1
h-1
l-2
o-1

The problem I'm running into is that if I put something like How now, brown cow? It should give me something like this

b - 1
c - 1
h - 1
n - 2
o - 4
r - 1
w - 4

but it doesn't instead the whole program crashes because of the punctuation marks and the spacing. Is there a way for me to fix that? All I know is that it has something to do with the alphabet[pos(letter)]++;

import java.util.Scanner;

public class CharCount {
static Scanner keyboard = new Scanner(System.in);
//this method should allow the user to enter a line of text (that should all be lower case) and then go to the printResults method
public static void main(String[] args) {
String text, character;
int count;
char letter;
int[] alphabet;
System.out.println("Enter a line of text:");
text = keyboard.nextLine().toLowerCase();// any text entered will be lower case
alphabet=countLetters(text);

Extract Higher-order Bits Of Random Number In Order To Get Longer Period

Mar 1, 2014

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?
