How To Convert String Into Int

Apr 16, 2014

I created a word object representing a specified string under my public class word method such as

Word w = new Word("Blue");

now I am required to return a hashcode for this word, which is an integer based on the words instance data under the method called

public Word(String w);
{
}

I am not sure how to convert the string into an int so I would be able to return a hashcode.

How To Convert Numeric String To Formatted String

Sep 11, 2014

I have a string value returned from a background tool that will range from 0 to possibly terabytes as a full number.  I want to format that number to use commas and to reduce the character count using an appropriate size modifier (KiB, MiB, GiB, etc).  I've tried converting the string number to a Double value using Double.parseDouble() and then performing the math based on the size of the value with this code:
 
Double dblConversionSize;
String stCinvertedSize;
dblConversionSize = Double.parseDouble(theValue);
if (dblConversionSize > (1024 * 1024 * 1024))
     stConvertedSize = String.format("%,.000d", dblConversionSize / 1024 / 1024 / 1024) + " TiB";
...
 
I've also tried using
 
     String.valueOf(dblConversionSize / 1024 / 1024 / 1024) + " TiB";
 
However, the formatting is failing and I'm either getting a format exception or the result is displayed as a number with no decimal component.

Cannot Convert From String To Boolean And Int To String

Apr 6, 2014

I have errors in the "if" and both "else if" ... The compiler says "cannot convert from String to boolean and int to String ...

instructions:

1. Add two private instance variables, String courseName and char grade to this class.

2. Add accessor and mutator methods for these instance variables.

3. Add a method register which receives an integer data type and returns String data type according to the argument passed to it ("Math" for 1, "English" for 2, "No course" for any other input)

What I have so far:

package assignment9;
 public class BannerUser
{
private int userId;
public int getUserId()
{
return this.userId;
}
public void setUserId(int userId)

[Code] ......

Cannot Convert From String To Double

Oct 4, 2014

//Students Full Name
firstName = JOptionPane.showInputDialog("Enter student " +
"first name.");
lastName = JOptionPane.showInputDialog("Enter student " +
"last name.");
// Get test grade (numbers)
[b]test1 = JOptionPane.showInputDialog("Enter test1 grade")[/b];

The line in bold is where that error comes up. I know it something simple but I can't remember. I declared both firstName and lastName as Strings and then the test1 I declared as double. I had a similar error in a previous assignment where I had a integer(age) input and then i had an output statement asking for a name all I needed to do was put keyboard.nextLine(); after my age input and I was fine.

Convert String To Integer

May 21, 2014

I have to make a programm where the user gives you the bank sorting code and the account number and you give him the IBAN. That was so far no problem and I was done within minutes except of one thing that I simply can't figure out even though im trying since weeks. At some point I have to convert a string to integer. My research told me its with parseInt() and I dont get a syntax error when I compile my programm (using BlueJ). But when executing the programm stops and gives me some weird bug message. Here is code and bug message:

Java Code:

public class IBAN {
public IBAN(String Bankleitzahl, String Kontonummer) {
Bankleitzahl=Bankleitzahl.replace(" ",""); // Die Leerzeichen werden entfernt
int Anzahl=Bankleitzahl.length(); // Auf der Variabel Anzahl wird die Anzahl der Zeichen von der Bankleitzahl gespeichert

Sadly String[] and Set are incompatible types.

About the same as using .add three times, but shorter.

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.

public static void main(String[] args) {

String enteredLine;
int leftStack, rightStack;
int leftQueue, rightQueue;

Java Algorithm - Convert String Of Numbers Into Text

Feb 18, 2014

I need a Java algorithm that converts a string of numbers into text. It is related to how a phone keypad works where pressing 2 three times creates the letter "c" or pressing 4 one time creates the letter "g". For example a string of numbers "44335557075557777" should decode where 0 equates to a space.

Java Convert String Of XML To Document Object Is Null All The Time

Apr 14, 2014

I am trying to parse a XML string into `org.w3c.dom.Document` object.

I have looked at solutions provided [here](xml - How to convert String to DOM Document object in java? - Stack Overflow), [here](How to create a XML object from String in Java? - Stack Overflow) and a few other blogs that give a variation of the same solution. But the `Document` object's #Document variable is always null and nothing gets parsed.

Here is the XML

XMLMappingValidator v = new XMLMappingValidator("<?xml version="1.0" encoding="utf-8"?>
" +
"<mapping>
" +
"<container>
" +
"<source-container>c:stem.csv</source-container>

[Code] ....

When I call
**v.getXML().toString()**
I get
`[#document: null]`

Clearly, the parse is failing. But I don't understand why.
