I must write a method that accepts a string and returns an int. The method should sum the unicode values of each character, so the string "ABC" should return 198. Also the only string class methods I'm aloud to use are length, charAt, and substring. I just don't know how the get the Unicode value.

This is my program.
public class C4
{
// instance variables - replace the example below with your own
public static void main(String[] args)
{
System.out.println((char)41);
}
}
I wanted to check that the integer 41 is 'A' in UTF-8, although it's ')' in UTF-16 , so I ran the program with javac -encoding UTF-8 C4.java but the result was still ')'.
How do i fix this? Also, do constants for the max values of ASCII and UTF-8 exist in Java? I need to show how many number of bits are used to represent characters in both encodings.

I use Eclipse (kepler version, with JDK 7) on MacBook Pro (Lion).I want to overwrite a line printed on my console. I used "" for that. I was expecting the cursor to go to the beginning of the line. Instead, it is going to the next line.
Code:
System.out.print("Superman
Sober");
Expected Output:
Soberman
Actual Output:
----------------
Superman
Sober

I have this small program that creates a sales opportunity and its related products, and then prints out the opportunity name, total quantity and total price
class Opportunity{
String name;
int Amount;
String Stage;
int Product_quantity;
[Code] .....
The code works as expected, and is successfully prints :
Opportunity Name: Sales
Opportunity Amount: 110
Opportunity Product Quantity: 3
That said, I feel the way the OpportunityCreator class sums up the quantities and prices (see the comments on the code) is very inefficient, and would only work if there were 3 or less products. How can I design this so that it sums the quantities and prices of all the Product objects that I create, regardless of how many of them are? I understand probably I'd need to redesign the whole thing but I'd like to get at least an idea of how this can be achieved.
Originally I was thinking of creating an ArrayList and adding all the prices/quantities there but wasn't sure how to do. I also thought of using a loop to loop through the different object references and sum the quantity/price but was also unsure on how to do so?

I am brand new to programming and java. I decided I wanted to learn programming so now I'm in a class. I am into my second week and my assignment is to generate 100, 3 digit numbers then add them together. I understand how vast java is, but as of right now we have only studied if/else/switch statements, I was able to get the 100, 3 digit numbers generated, but I cannot add then together.
import java.util.Random;
import java.util.Math;
public class ThreeDigitGenerator {
public static void main(String[] args) {
int sum = 0;

public static void displayOutputs (int[][] anArray) {
System.out.println("Here is your 2Dim array:");
for (int i = 0; i < anArray.length; i++) {
System.out.println(Arrays.deepToString(anArray));
}
}
This is my code and I get this as a result when I input 10,20,30,...,90 into array[0][0], array[0][1], ..., array[2][2] (3rows, 3columns array)
[[10, 20, 30], [40, 50, 60], [70, 80, 90]]
[[10, 20, 30], [40, 50, 60], [70, 80, 90]]
[[10, 20, 30], [40, 50, 60], [70, 80, 90]]
While I expect to get only
[10, 20, 30]
[40, 50, 60]
[70, 80, 90]
I get no errors at least when I have the same # of rows and # of columns. However, when I have more columns than rows, a compiler stops running when it runs columnSum method.Here's an error message.
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 2
at lab10.Array2DMethods.columnSum(Arrays2DDemo.java:70)
at lab10.Arrays2DDemo.main(Arrays2DDemo.java:111)
Java Result: 1
And here's my code
public static void columnSum (int[][] anArray) {
int sum =0;
for (int col=0; col < anArray.length; col++) {
sum=0;
for (int r = 0; r < anArray[col].length; r++ ){
sum += anArray[r][col];
}
System.out.println("Sum of column " + col + " = " + sum);
}
}
why my code doesn't work when I have more columns.

What I am trying is find the XOR value between charcters of a String here is my code
public static void main(String[] args) {
System.out.println(grayCode("100"));
}
public static String grayCode(String input){
StringBuilder temp=new StringBuilder();
temp.append(input.charAt(0));
for(int j=1;j<input.length();j++){
char previous=input.charAt(j-1);
char current=input.charAt(j);
char xorVal=(char)(previous^current);
temp.append(xorVal);
}
return temp.toString();
}
but I am not getting actual XOR value of two charcters that I am trying to get.

My program is supposed to use recursion and iteration to sum and reverse elements in an array of Longs. The array is supposed to be 1000000 cells and I am supposed to compute the average times of 99999 trials. When I try to run the program, it keeps saying running.... but doesnt ever do anything.
public class PA2Delegate {
private long[] start;
private long[] end;
private Long reversal;
private Long sum = (long)(int)0;

I am trying to sum up the elements of an array. When I test my code the sum is always off by one. For example if I input: 20, 40,30 it gives me 89 instead of 90.
This is what I have so far:
public static void main(String[args]){
int size = kbd.nextInt();
int [] myArray = new int [size]
//user inputs the elements of array

Recently I switched a RCP/swing app from using hypersonic to mysql. The problem is that there are some unicode characters in the data. The data now displays with the unicode characters as unicode in the app. I tried printing out the data from the bean and it comes out the same way on the console. If I cut/paste the string from the console and place another print statement inside the bean I get output with unicode from the field and formatted output from the other print statment. Why???
public String getText(){
System.err.prinltn(text); //this is the actual value that comes in from the database
System.err.prinltn("u00e");//this is the cut/past value of what the above line prints except this shows in the console correctly
return text;
}

public void loop4() {
char alph = 'a';
while(alph <= 'z') {
System.out.println(alph);

I developed some servlet to get unicode parameters via post request. It worked perfectly fine since I set the encoding as below:
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
HttpSession session = request.getSession(false);
response.setCharacterEncoding("UTF-8");
response.setContentType("text/html");
request.setCharacterEncoding("UTF-8");
String fileContent = request.getParameter("fileContent");
}
Now that I have set up my dev environment on a new machine with new eclipse, it does not work.
It displays Ï instead of π.
I've already tried adding URIEncoding="UTF-8" to server.xml which did not work since it only affect get not post. I figured out how to get the parameter with correct encoding on the new system:
String[] parameters = URLDecoder.decode(request.getQueryString(), "UTF-8").split("&");
But I cannot believe that this is the solution because then what's the point of having request.getParameter. I already know that:
String sss = new String(fileContent.getBytes(),"UTF-8");
would not work.

I need a way to store the pixels values currently on the screen and compare them to the values on the first frame. Right now I'm using glreadpixels as follows:
currentBuffer= BufferTools.reserveByteData(mapSize);
glReadPixels(mapStartX, mapStartY, mapWidth, mapHeight, GL_BLUE, GL_UNSIGNED_BYTE, currentBuffer);
for (int i = 0; i < mapSize; i++) {
if (currentBuffer.get(i) != baseBuffer.get(i)) {
//Do nothing
continue;
}
//Do something
}
This works perfectly fine but turns out to be a real bottleneck, dropping the fps to a third of what it was. Is there any quicker way? All I'm after is speed, I don't even need to show it on the screen if the comparison is made "behind the scene".

I have a question in mind that this is my registration form. I am sending these values from HTML form to server and database. I have question that in my case if I click next to Add Another Mobile no in HTML.then a block is genereated and each time a new name is generated.
My Question is if I click 6 times then 6 name attribute are generated. How can I send and differentiate them on my server side.
Because at their I will use something request.getAttribute("Attr_Name");
But they are same. How to do this?.

I have a JScrollPane with two coulmns. In the first column I have an image pane JTable, and in the second a list with names of sections. This second column I try to divide in two columns, one (the second column) to display the names of the sections (each row contains one name), and in the other column (the third) I want to show some values for every section in the row respectively. But, instead of displaying the desired values in the third column, I get the same names of the sections as in the second column.
