Write A Method That Returns Unicode Values Of A String?

Oct 25, 2014

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.

Character Encoding - Constants For Max Values Of ASCII And UTF-8

Mar 22, 2014

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.

Code:

System.out.print("Superman

Expected Output:

Actual Output:

Sales Opportunity - Summing Up Variables?

Aug 7, 2014

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?

Random Number Generator Then Summing

Aug 29, 2014

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;

Summing Columns And Displaying Array

Apr 24, 2015

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.

How To Find XOR Value Of Character Of Character Array In Java

Mar 3, 2015

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.

Swing/AWT/SWT :: Cannot Convert Unicode

Feb 26, 2014

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;
}

Servlets :: Unicode Post Request Parameters

Feb 10, 2014

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.

Store Pixels Values Currently On Screen And Compare Them To Values On The First Frame?

Aug 29, 2014

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".

Instead Of Different Values In Two Columns Per Row In Jtable Getting Same Values

Feb 5, 2014

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.
