public AsymmetricKey readKey(String filename)
{
StreamReader reader = new StreamReader(filename);
String modulus64 = reader.readLine();
String exponent64 = reader.readLine();
byte[] modulusBytes = base64Decode(modulus64);

When I try to convert this value, "Testingu2120" (along with UTF coed u2120)comes as a string as part of SOAP response. I need to convert this UTF-8 characters in to a symbol, in this case it is SM (Service Mark) symbol and show it on the UI.
How can we achieve this in JAVA?
I have four different UTF-8 character set to convert.
TM - u2122
SM -u2120
R - u00AE
C - u00A9

I'm having trouble getting the text entered in my JTextField to be converted to the conversion formula. The line I'm getting error in is:
String text = text.getText();
Also I created another JTextField in which I want the answer to be displayed in, but I'm not too sure how to go about that.
This is my attempt at it, but it doesn't work because it doesn't make sense;
result.setText1(Integer.toString(celsius));
import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
public class TempConversion extends JFrame
{
private final JLabel ask;
private final JLabel result;
private final JTextField text;
private final JTextField text1;

I have a piece of code as below for date format conversion.
DateFormat formatter1 ;
DateFormat formatter2 ;
Date date = new Date();
formatter1 = new SimpleDateFormat("yyyy-mm-dd");
date = formatter1.parse("1952-12-10");
System.out.println("before format, date is " + date);
formatter2 = new SimpleDateFormat("dd-MMM-yy");
formatter2.format(date);
System.out.println("after format, date is " +formatter2.format(date));I would like to change 1952-12-10 become 10-DEC-52, h
However, I am getting below output:
before format, date is Thu Jan 10 00:12:00 MYT 1952
after format, date is 10-Jan-52

<h:outputText value="#{secondClassController.funcSecondClass(#{firstClassController.funcFirstClass()})}" />
[...]

I like to know how to write root function in java applet. I know it in java function. Ex:
import java.lang.*;
public class Maths {
public static void main(String[] args) {
// get two double numbers numbers
double x = 9;
double y = 25;
// print the square root of these doubles
System.out.println("Math.sqrt(" + x + ")=" + Math.sqrt(x));
System.out.println("Math.sqrt(" + y + ")=" + Math.sqrt(y));
}
}
working fine. but If I tried in applet it's not working. Ex:
evap_trans = 0.0135 * SRAD * ( TMEAN + 17.78) * Math.sqrt(TMAX - TMIN);
If I execute above said formulae with out "Math.sqrt" results are ok. If I used then results shows ZERO.

I need to convert c# function to java method. The important thing is String strKey. Parameters for testing are strMask= 4634958 and strSN=1394901184 and the result must be strKey = 2156325482!!! The result that I am getting with my Java code is 2138641814.This is C# code:
public static bool Key (String strMask, String strSN, ref String strKey)
{
System.UInt16 wLo, wHi;
System.UInt32 dwSNx, dwKey;
System.UInt32 dwSN, dwMask;
if (strMask=="") strMask="0";

There is an error in my code that pops when I tried to execute my java application for an exponent function that I wrote. Here is my code and here is the error is generated when I run my code:
//a java application that calculates the power of an integer in a method that the user creates
//and uses a while loop to do so. User cannot use any Math class methods to perform this calculation
import java.util.Scanner;
public class exponentiation{
//main method begins execution of java application
public static void main(String[] args){
[code]....
Why is it an illegal start of an expression? I didn't think you needed to used if statements for a whileloop.

I am making a pizza program and most of the program works. I have made an order button that will output the total price of the order. The reset button that I made makes the JTextArea output $0.00, but if I press the order button to make another order, the program does not add the new amount to zero. For example, if I make an order that totals $5.00, but I want to make another order after resetting, the price for the new order will be added on to the previous order's price.
Here is the code. This is a JApplet program. Why the price will not reset? This code was made in BlueJ.

So I have a program for a project that permutes a random series of numbers using Java's Rand function. Basically I use a seed and a number of items I want in the arrangement of numbers, and the program makes a permutation with no two numbers being repeated. Only arrays can be applied to it, so I've been hard at work finding a solution.
Here's the code so far:
public static int permutation[];
public static void permute(int numOfItems, int seed){
permutation=new int[numItems];
Random rand = new Random(seed);
permutation[0]=rand.nextInt(numItems-1);
[Code] ......
So basically I'm wanting the program to make a randomized list of numbers from the number of items I pass to the Permute method with no duplicates. I'm having some level of success with what I have written, as it gives me a randomized list when printing the output, but for some reason the first for statement in code never terminates fully, but instead runs indefinitely when generating the last integer.
For example, if I want to put 10 with a seed of 0 into it and make a list from 0-9, it will print 74283510, which is only 8 different integers. permutation[0] is manually set at the beginning of the method, which accounts for one more, but that's still only a list of 9, so I'm just wondering why the last integer is not being generated and why the program keeps looping and not terminating? I'm know for sure it's something I'm overlooking.

I have deduct a number of days excluding holiday and weekends .So if I have to deduct 4 days from current day (02/12) and assuming 02/10 is a holiday my answer will be 02/05
Now below is the code I have come up with however its not working with the hardcoded dates I am passing in to the Holiday Calendar String .Only the last value is considered . How I should store this values and compare with the date
package date_calculation;
/**
* Returns a tick for each of

How to improve my code. I finally was able to create a program that gives you the corresponding letter grade, when you enter in a numeric grade without using an array. The only issue left is that I have to be able to enter 5 grades at a time, and it give me the letter grade for all 5. I have the programming working, but only am able to enter 1 at a time. I am not sure what kind of loop or if I am supposed to use a loop.
public static void main(String[] args){
{
int grade = 0;
Scanner input = new Scanner(System.in);
System.out.println("Enter : ");
grade = input.nextInt();
if (grade >= 90)
