How can I convert JSON string to HashMap. My JSON string is like
{
"AvailableDeliveries": {
"500": {
"code": "INOFFICE",
"desc": "In Office",
"id": 500,
[code]....
I looked on other examples which have collection of object but I have this extra top level object "AvailableDeliveries" not sure how to handle that level.
I have a json file with the content:
{
"id" : 10,
"name" : "book1",
"user" : "john",
"chapters" : [
{
"chaptername" : "chapter1",
"content" : "index"
}
]
}
I want to convert it with a nice format (e.g. tree format or table).
I have a table which contains list of regular expression and its corresponding value.I have to fetch those value and put it HASHMAP where regex as key.I have to compare the each key with the given string(input) and If matches I have to get the corresponding Value for the regex.
View Replies View RelatedI need assigning the selected hashmap values into a list and to display the values in a jsf page. The user will select certificates and will be stored in the below list:
private List<String> selectedCertificates = new ArrayList<String>();
The selectedCertificates will have the values ("AA","BB"). Now I will be passing the list into a hashmap in order to get the names and to display them on the jsf page.
My code is below:
Map<String, String> CertificatesNames =
new HashMap<String,String>(selectedCertificates.size());
CertificatesNames.put("AA", "Certificate A");
CertificatesNames.put("BB", "Certificate B");
CertificatesNames.put("CC", "Certificate C");
for(String key1: selectedCertificates) {
System.out.println(CertificatesNames.get(key1));
}
I want to display in my jsf page :
Certificate A
Certificate B
Now my issue is that is how to display all the values of the CertificatesNames.get(key1) in the jsf page as I tried to do the below and it printed all the values when I used the #{mybean.beans} using the :
List beans =
new ArrayList(CertificatesNames.values());
So how to do this?
How can I convert number to string in java. Something like
public void Discription(Number ownerName){
String.valueOf(ownerName);
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.

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>

When I call
**v.getXML().toString()**
I get
`[#document: null]`
Clearly, the parse is failing. But I don't understand why.

I have a JSON string
Java Code: {
"AvailableDeliveries": {
"500": {
[Code]....
Number of JSON object can vary. I tried to generate POJO from jsonschema2pojo but it generate fix number of object inside AvailableDeliveries class. How I can define a POJO with collection of object and map corresponding field for above JSON string. I can't change the structure of JSON response as I am consuming the string.
I have the following hashMap declared:
private HashMap<String, Car> cars = new HashMap<String, Car>();
How can i get an array of String filled with hashMap keys?
When learning HashMaps in C++ I had to create the whole algorithm. In the code I created I could simply place a string into the method and it would store the names for me by turning the string into a integer and storing is accordingly. If there was a collision it would grow linearly at that location.
//play with Hash Tables
void getNames(String names) {
HashMap<String, Integer> map = new HashMap<String, Integer>();
map.put(names,22);
}
How can I do this in Java. I read about them and look at examples and they all for the most part look like this.

How do I turn this information into java objects?
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.

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)

How can i convert int to string ? The error I get is count cannot be resolved.
System.out.print("How many days?: ");
numberOfDays = keyboard.nextInt();
for(int count = ':';count <=memberCount; count++ )
System.out.print("What is band member # " + "'s name?");
memberName = keyboard.nextLine();
System.out.print("What is"+ memberName+"'s instrument?");
instrument = keyboard.nextLine();
members +=(count.toString() +":" + memberName +" -" + instrument + "" );
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.
//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.
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

I want to store a String.split("seperator") to a Set<String>.
Example:
Java Code: Set<String> = (Set<String>) "a|b|c".split("|"); mh_sh_highlight_all('java');
Sadly String[] and Set are incompatible types.
About the same as using .add three times, but shorter.
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.
import java.util.Stack;
public class Palindrome {
public static void main(String[] args) {
// TODO Auto-generated method stub
String enteredLine;
int leftStack, rightStack;
int leftQueue, rightQueue;

I am having problem in converting JSTL variable into integer type in JSP (not using Spring). I am looking to do something like below:
<c:set var="total_amt">${list.totalAmount}</c:set>
<c:when test="${new Integer(total_amt) > 500}">
String pass= passordFelt.getPassword();
I could not cast it to String
String pass= (String) passordFelt.getPassword();
But I need that password to be String,cause i need it to be sent to getConnection(url,user,pass) where pass is a String type.
