Converting HGT Files To Proprietary Format
Sep 16, 2014
I have to read SRTM .hgt binary files in Java and then rewrite them in a binary proprietary format. The format is to write the .hgt file as 2-dimensional binary array of either 1 byte, 2 byte, 3 byte or 4 byte integers in BIG ENDIAN format. I have chosen short as the data type(2 bytes) because I believe the data in the .hgt file has the maximum value of 32767. I am enclosing the code here - how do I read the data into 2-dimensional array ?
Java Code:
FileChannel fileInputChannel = new FileInputStream(fileInput).getChannel();
FileChannel fileOutputChannel = new FileOutputStream(fileOutput).getChannel();
int size = (int)fileInputChannel.size();
[code]....

The below is the existing data in a file running over 24768 lines
There are duplicate names link (abc) , width and FLof which stands for offset
file A
------------------
###########################################################################
# F Name Gro Width FLof Class
###########################################################################
1cbb abc - 6 2 INDIRECT
1cbc xyz - 3 0 INDIRECT
1cbd abc - 4 0 INDIRECT
1cf3 bcd - 3 5 INDIRECT
1cf4 pqr - 3 0 INDIRECT
1cf5 bcd - 8 0 INDIRECT
---------
---------- so on
I want a script to convert the file data to as folowing data :
file B
-----------------
###########################################################################
# F Name Gro Width FLof Class
###########################################################################
1cbb abc_7_2 - 6 2 INDIRECT
1cbc xyz - 3 0 INDIRECT
1cbd abc_11_8 - 4 0 INDIRECT
1cf3 bcd_7_5 - 3 5 INDIRECT
1cf4 pqr - 3 0 INDIRECT
1cf5 bcd_15_8 - 8 0 INDIRECT
Explanation for conversion is here :
first row abc has width as 6 and FLof as 2 in file A, so it occupies position 2,3,4,5,6,7 accounting to 6 position so represented as abc_7_2 in file B
Now row three of file A has duplicate of abc so now the new offset will be previous offset plus one ie. position will start from 8 and it goes as follows 8,9,10,11 so represented as abc_11_8
This will create unique and informative names, the same goes with other rows :
</pre> mh_sh_highlight_all('xml');

In a program I created, I'm using a text file that contains some texts needed for the program. The method relevant to this is something like the following.
private String wordgen(){
try {
BufferedReader reader = new BufferedReader(new FileReader("src/Resources/adjectives.txt"));
Random rand = new Random();
int low = rand.nextInt(400);
String fil="";
int i=0;
while(i!=low){
[Code]...
The program runs fine in netbeans project but once the jar is created it does not corporate with the text file. ("null" is returned) How can I attach text files to jar and exe?

I need to transformation the txt files into xml files, but each row txt files don't have same elements, for example the first book is composite one author
<books>
<book>Title</book>
<price>price</price>
<author>Author</author>
</books>
but the second book is composite two author
<books>
<book>Title</book>
<price>price</price>
<author>Author</author>
<author>Author2</author>
</books>
I would have the xml files with the number of authors variables, I can use JAXB for my problem?or not?

I'm converting from ASP to Java for a legacy site. I believe the first part of the if statement is right but I'm having an issue within the else staetment. I'm getting date is undefined, I've tried using getYear and getDate but have not been successful.
ASP:
If Request("action") = "results" Then
aMonth = Request("selMonth")
aDate = cint(Request("selDate"))
aYear = cint(Request("selYear"))
Else
aMonth = UCase(MonthName(Month(Date()),true))
aDate = Day(DateAdd("d",-1,date()))
aYear = Year(Date())
End If

I try to use below codes to convert Hex String "1111737999630745" to ASCII.
When I read the result in Notepad++ with HEX-Editor plugin, I find attached image which is different from above String, there is one additional c2 and I am quite confused.
Java Code:
public static void main(String[] args) throws IOException {
Test strToHex = new Test();
File file = new File("D:/filename");
// if file doesnt exists, then create it
if (!file.exists()) {
file.createNewFile();

I was reading about the char data type in Java. I know that an unsigned 16 bit integer is used to represent a char. So we can write the assignments below:
char a = 65; // a will get the value 'A'
But the limit of the char value is 65535.
So I've tried out a few things with char and trying to understand them but I'm not sure how they work.
char a =(char) 70000;
char b = (char) -1;
In the first case I thought that 70000 % 65535 would happen internally and the unicode character present at that location would get stored in 'a' but if I do that I get the answer of 70000 % 65535 as 4465. But when I display 'a' it shows me the output as '?'. Clearly '?' isn't at 4465.
In the second case I have no clue what's happening but somehow when I display 'b' it shows me '?' again.

I have this project due and its asking that i print out what type of triangle it is when the user inputs 3 sides. I have most of it done and working, but it pops up different windows instead of using one window for everything. The assignment says it needs all the final info to be in one window. The boolean is coming from another method. I'm unsure how to get it into a string (Or if that's what i have to do). The method must return a boolean true/false.
import javax.swing.*;
public class Triangle {
public static void main(String[] args) {
int side1 = getSides();
int side2 = getSides();
int side3 = getSides();

In my Java class, the last assignment we had to turn in was to create a program that would take a users input and create a new type of animal. I went through the different steps in the instructions, and everything seemed to be going well up until the point where we actually took the users input and created the new animal. Specifically, I kept getting an error stating that I could convert a String to an animal.
I'm attaching the main class (Animal), one of my animal classes (Bird) and the class where I'm getting the error (AnimalStuff). I turned the program in as is, so what's done is done, but I'd like to learn what I'm doing wrong and what I can do better. I do know that the loop in AnimalStuff is wrong as it doesn't work right either, but I'm more concerned about the conversion from String to animal, as the entire program depended on this to work, and it doesn't.
public class Animal {
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
}
public static String kind;
public static String integument;
[code]....
Is there anything that jumps out at to what I'm doing absolutely wrong?

I've started writing a new program that Scans for some strings. I want to specify a random Integer to those Strings in order to do my desired idea. what should I do?!! my codes are here :
import java.util.Random;
import java.util.Scanner;
public class Draw {
public static void main(String[] args) {
System.out.println("This Program is written to solve little problems in families cause of doing unwanted works!!");
[code].....
now I want to Specify an Integer to each person that has been scanned! for example if the first person is " David " , which is a String, in the next step :
Random randomNumber = new Random();
randomNumber.NextInt(101);
int David = randomNumber.NextInt(101);
I want to what should I do?

how to make an applet out of this program but can't seem to do it.

Technically, when you run the program, a gif page appears (that I put as a placeholder) and when you press the letter 'n' JCreator runs the program, displaying a character P on a .txt field made using the Notepad on Windows. You can move it left, right, down, and up andf it will move accordinly. However, each time I make such action, the compiler has to rewrite to whole .txt field with the new position.
My former tutor said that in order for it to be "real-time", we have to use an applet.

I'm trying to complete a code to convert decimal to octal. however i can't figure out how to print the output correctly. it should be.. Your integer number 160000 is 0470400 in octal. (160000 is the number you input). My code is...
Scanner input = new Scanner(System.in);
int value;
int a;
int b;
int c;
int d;
int e;
int f;
int g;
String result;
[Code] .....
Lastly, my output prints everything correctly, but the input number always is 0.
Ex error: input= 160000
Your integer number 0 is 0470400 in octal.
it should be.. Your integer number 160000 is 0470400 in octal.

how to write the toString to convert this output :
List:
side: 14 color: java.awt.Color[r=0,g=0,b=255]
side: 18 color: java.awt.Color[r=255,g=0,b=0]
side: 12 color: java.awt.Color[r=255,g=255,b=0]
side: 18 color: java.awt.Color[r=255,g=0,b=0]
side: 16 color: java.awt.Color[r=0,g=255,b=0]
side: 10 color: java.awt.Color[r=255,g=200,b=0]
side: 10 color: java.awt.Color[r=255,g=200,b=0]
to this output
side:14 color:#0000FF
side:18 color:#FF0000
side:12 color:#FFFF00
side:18 color:#FF0000
side:16 color:#00FF00
side:10 color:#FFC800
side:10 color:#FFC800
here is how i have it written now

{
return "side: " + side + " color: " + color + "";

I am taking Python this semester. Our teacher wants us to convert Python to JavaScript without really explaining how or/and expecting us to be familiar with it already.Python Program I have is pretty simple - it prompts you to enter your first and last name and end your DNA string, "CAG" repeats are counted by another function and the result is passed to function that identified weather you may have huntington's decease or not.
<body>
<p>Enter First Name: <input type="text" size="25" id="firstname" value="">
<p>Enter Last Name: <input type="text" size="25" id="lastname" value="">
<p>Enter DNA: <input type="text" size="25" id="DNA" value="" >
<p><button onclick="alertt(f,l,d,c,p)" style="background-color:pink"><b>PRESS TO FIND OUT RESULT</b></button></p>
<script>
[code]...
When I run it there is an issue with countCAG and prediction functions :( I would run each one individually in JS console and I get Undefined, or InvalidString I read that I am supposed to use var in front of each variable, unlike in Python where you just assign variable a value without any add-ons in the front. But JS console seems to recognize both ways of assigning, however var smth=0 immediately evaluates to Undefined, and smth=0, gives me 0...

I am trying to display the contents of my Object but when I compile it I get this:proj4.TellerQueue@1db9742
I am pretty sure it's because I havent created my own toString method but I could be wrong. If this is the case, what do I need to do to properly display the variables of my object? Right now my class, BankQueue, contains another object called Person, which contains a String and int variables. I want to do something like this:
class BankQueue{
Queue<Person> q = new LinkedList<Person>();
public String toString(){
return q.;//display contents of the q

I'm new to coding and we have an assignment for class to convert fahrenheit to celsius so far this is what i have:
import java.util.Scanner;
public class Lab5 {
public static void main(String[] args) {
//variable dec
Scanner scan = new Scanner(System.in);
double input;
[code]...
This is what he wants us to do "Write a method name celsius that accepts a Fahrenheit temperature as an argument. The method should return the temperature, converted to Celsius. Demonstrate the method by asking the user a temperature value to convert. Then below the result, call a loop that displays a table of the Fahrenheit temperatures 0 through 20 and their Celsius equivalents."

book, this book is good. that book is good.
cook, cooking is enjoyable.
After printing output of array:
book,this one is good
that book is good, null
what is wrong with this code?
Code is :
public static void main(String[] args) throws Exception {
Scanner main = new Scanner(new File("C:UsersaDesktopook1.csv"));
int line=0;

The idea behind this program is that the program prompts the user to input an initial base (2-36), which checks to ensure that it is a valid int, then asks for a number to convert (which is taken as a String), then it asks which desired base the user would like to convert said number to. I have a basic program that is not complete, but allows me to do a few conversions using convertTo. I believe that I am going to have abandon this method and try mathematically converting every number. This leads me to what I can and cannot do. I am unable to use the initialBase as a condition to know what kind of number i an converting. For instance, I don't know how to make program know that if "2" is the initialBase, that that means that the String is a binary number. THAT is what I'm having problems with.
Here is my initial program that has a few things that are copied and pasted from other bits of my code in my program:
XML Code: Url...
I have broken down what I (think I) need to do here: Check to see if the input base is 2, 8, 10, 16, or 32. Hint: Put the possible bases in an array, and check the input base against the array. Check to see if the input number is valid for the base. Hint: Create a String "0123456789ABC...V" and compare each input character with the first "base" characters of the String. Check to see if the output base is 2, 8, 10, 16, or 32. Hint: Use the same possible bases array you used in step 1 to verify the input base.Check to see if the input base is equal to the output base. If so, print the input number. Perform a conversion from the input base to base 10. Perform a conversion from base 10 to the output base. You do this in 2 steps because it's easier to check each conversion separately.Output the converted number.
