Adding Characters To Result Stack

Feb 21, 2014

Right now I have three stacks. Each stack holds characters, with the normal operations of pushing and popping. I am trying to compare two characters from stack1 and stack2(each character is a digit character). I would like to be able to do arithmetic on the digit characters and the push the answer on to a result stack.

Ex.) I pop character '3' from stack1 and '5' from stack2. Then I add the two. equaling '8' and pushing that character on to the result stack. This will hopefully in turn allow me to add arbitrary large numbers that integers will not support.

I am having trouble because I believe I am getting some ascii character values when I pop off the result stack. here is a small piece of my code

public void addition() {
char temp1 ,temp2;
int i = s1.getSize();
for(int j= 0;j<i;j++) {
temp1 = s1.pop();
temp2 = s2.pop();
if(temp1+temp2>=10)

[Code] .....

Stack Is Filled With Numbers And Characters

Oct 31, 2014

I have a Char stack: ArrayStack<Character> stek=new ArrayStack<>();

The stack is filled with numbers and characters (only '+' and '*' ), but I need to make calculations, so I need the INT values of the numbers i pop from the stack. So each time I need to make a calculation, I have to pop two numbers, convert them into INT ,then add/multiply them, and put them back into the stack again, but as CHAR (because the stack is not accepting them to be added as INT)

int a= Character.getNumericValue(stek.pop()); //stack no1
int b= Character.getNumericValue(rezultat.pop()); //stack no2
int tmp=a*b;
char tmp2 = (char) tmp;
stek.push(tmp2);

Stack - For Loop Not Returning Proper Result

Jul 18, 2014

Below is a method that is suppose to insert a value inside a stack based on the index. I thought it would be easier to copy the value, if any, that was in the index into the variable holder and replace it with the input value. After in which it would copy the holder value and place it at the top of the stack. (topOfStack variable is what the holder is copying too.)

public void pushExact (int index, String input) {
String holder = "";
if (maxSize == 0) {
theStack[topOfStack] = input;
topOfStack++;
} else if (topOfStack + 1 < maxSize) {
for (int n= maxSize - 1;n >= 0;n--) {

Stack Is Adding Same Values

Jun 16, 2014

In my application a series of inputs and a calculated result. At the end of each loop these inputs and calculations are displayed. After the loop is over with the user does not enter a string that is "y" or "Y", I want these inputs and the calculation to be displayed in a First in First Out format or a stack. I am using a LinkedList that is used in a class creating a stack.

Here is the code for my stack.

Java Code:

import java.util.LinkedList;
public class GenericStack<E> {
LinkedList<E> stack = new LinkedList<>();
public void Push(E element) {
stack.addFirst(element);

[Code] ....

Here is the code containing the main method. The methods other than the main method are probably not relevant to the problem, but take a look if you like.

Java Code:

import java.util.*;
import java.text.*;
public class FutureValueApp
{
public static void main(String[] args) {
GenericStack<String> stack = new GenericStack<>();

[Code] ....

The stack seems to be adding the same inputs and the same calculation from the first loop, even when it is on it's 2nd or third loop. I am getting this output.

Java Code:

Monthly Inv.Int. RateYearsFuture Value
$5.002.0%5$315.76
$5.002.0%5$315.76 mh_sh_highlight_all('java');

Loop That Stops Printing A File And Adding To Stack

May 6, 2015

I'm supposed to add characters to a stack and pop them once the adjacent delimiter is read in from a text file. Moreover, program is supposed to print out the incoming text from the file, but stop when the applicable delimiter is not on top of the stack. As in, a '[' doesn't have a ']'.

I've got the program so it can pop and add to the stack correctly, and stops adding at the correct time, but I cant seem to get it to stop printing. I know a switch statement method in another class seems obvious, but I was trying to practice nested loops.

This is the main program:

import java.io.*;
import java.util.Scanner;
import java.io.IOException;
import java.util.Stack;
public class DelimiterChecker {
public static void main(String [] args) throws IOException {

[Code] ......

Moreover, the file I'm reading for is simply:

{
System.out.println(1)
System.out.println(2)
System.out.println(6 <-------------missing delimiter
System.out.println(7)
}

Strings In Java - Adding Characters

Jan 13, 2015

It works when i do this ,
 
String a = "*";
for(int i = 0; i++; i<10){
 
System.out.println(a);
a = a +"*";
}

but it doesn't work the other way,

String a = "***************";
for(int i = 0; i++; i<10){
 
System.out.println(a);
a = a - "*";
}

I searched about this online and read strings are unmutable in java but what does that exactly mean ? If the string cannot be changed how i am able to add the characters but not remove them.

Counting Duplicates In A Stack

Apr 11, 2014

Write a method compressDuplicates that accepts a stack of integers as a parameter and that replaces each sequence of duplicates with a pair of values: a count of the number of duplicates, followed by the actual duplicated number. For example, suppose a variable called s stores the following sequence of values:

bottom [2, 2, 2, 2, 2, -5, -5, 3, 3, 3, 3, 4, 4, 1, 0, 17, 17] top

If we make the call of compressDuplicates(s);, after the call s should store the following values:

bottom [5, 2, 2, -5, 4, 3, 2, 4, 1, 1, 1, 0, 2, 17] top

This new stack indicates that the original had 5 occurrences of 2 at the bottom of the stack followed by 2 occurrences of -5 followed by 4 occurrences of 3, and so on. This process works best when there are many duplicates in a row. For example, if the stack instead had stored:

bottom [10, 20, 10, 20, 20, 10] top

Then the resulting stack after the call ends up being longer than the original:

bottom [1, 10, 1, 20, 1, 10, 2, 20, 1, 10] top

If the stack is empty, your method should not change it. You may use one queue as auxiliary storage to solve this problem. You may not use any other auxiliary data structures to solve this problem, although you can have as many simple variables as you like. You may not use recursion to solve this problem. For full credit your code must run in O(n) time where n is the number of elements of the original stack.

I wrote a code but still having a problem with it , am I allowed to use 3 while loops ?

public void compressDuplicates(Stack<Integer> s ){
Stack<Integer> backup= new Stack<Integer>();
int count = 1;
while(!s.isEmpty()){
int temp = s.pop();

[Code] .....
 
// example 1

Expected output : bottom [5, 2, 2, -5, 4, 3, 2, 4, 1, 1, 1, 0, 2, 17] top

My output: //bottom [17, 2, 2, 2, 2, 2, -5, -5, 3, 3, 3, 3, 4, 4, 1, 0, 17, 17] top

How To Take Top Of Stack And Convert It To String

May 2, 2015

For my classes I wrote I have puts strings into a stack and also a queue and am wondering how to take the top of the stack and the front of the queue and turn those into strings in my main class and run them through while loops that will detect if they are palindromes or not. Right now I am trying to peek and use first to put in my while loop but they don't work with the .charAt because they are not considered strings I think.

Program For Implementing A Stack

I tried to write a program to implement a stack but it has a bug I am unable to solve.The bug is that whenever I choose an operation to perform, eg push, After performing the operation, the loop is executed once again and Invalid choice message appears, i.e. the default case. And then the loop again executes to choose further option. Here is my code

Stack Overflow Error

Oct 22, 2014

I am getting a stack overflow error for my method that recursively gets the height of an AVL tree. The odd thing is that it returns the height of the tree the first time I call that method, but when I call it again later on, I get that error, which I does not make any sense to me. I have a base case, where it is supposed to stop when the node is null, but it never reaches that. Also, when I print out the values, it alternates b/w three values: 5, 4, and 24. Something else, which I think is important to state, is that if I put the print statement before my base case, the IF, I get a warning stating that my entire IF statement is dead code...but why?

is that everytime I insert/delete a value into the AVL tree I must make sure that it is height balanced (none of the siblings may have a difference in height from each other > 1); if its not height then I rotate certain nodes accordingly. The first 10 items that I input are: 100, 50, 24, 200, 190, 10, 5, 190, 100 and 4. The pre and in order prints of these, from the console are:

PRE ORDER: 100 10 5 4 24 50 200 190 100 190
IN ORDER: 4 5 10 24 50 100 100 190 190 200 .

private int rheight(AVLNode<E> node) {
//if i put the print statement here, my IF becomes "dead code"
if(node == null){
return 0;
}
else{

Linked Stack With Directory Won't Print

Apr 14, 2014

Im trying to create a linked stack that will hold the starting directory to the current directory, so that when i finish a directory it would go back to the parent. as i go through the files in a directory and find a child directory, i have to stack current directory and process the child directory, when thats done, pop the parent from the stack and continue processing it. Here is my code:

//import io File and ioexception
import java.io.File;
import java.io.IOException;

/*create class that will take a path to a directory, print the name of the argument directory, print the name of each file and directory in argument directory. Prints the directory name and each file and directory inside*/

public class dirStackPrint

[Code] .....

when I run the program, nothing prints, why is that? I'm having trouble understanding the processing of the top, push and pop functions, i have them in my code but they don't seem to be working as they should?

Loop Not Popping Off All Item From Stack

Sep 30, 2014

When I try popping everything off my stack, it leaves the last item alone. The size comes out correct when I print it out, so that cant be the issue, I think. Also, it doesnt even print it out if I do

for(int i = 0; i <= s1.Size() + 1; i++)

it still leaves one value left. What am I doing wrong?

public class Test {
public static void main(String[] args) {
Stack<String> s1 = new Stack<String>();

s1.Push("first");
s1.Push("2nd");
s1.Push("3rd");
s1.Push("4th");
System.out.println(s1);
try {
System.out.println("The top item is: " + s1.Peek());
