How To Take 1 Milion's Of Character As A Input
View Replies View RelatedI am trying write a program that accept an input and present the input with every 5th character replaced with X (count spaces also).
For example:
input: "hello my name is mario"
outpu: "hellX my Xame Xi maXio"
I only manage to replace specific letters, e.g every "m" letter.
What should be the code if i want to input a different string in case of the typed string. The case is : I have a predefined string S = "Peter,please answer my question" and now when i input another string inside the text field character by character i want characters from the string S to enter instead of the input string. In short, the input string should be disguised as string S.

// TODO Auto-generated method stub
File file=new File("D:/input.txt");
java.io.FileInputStream is=new java.io.FileInputStream(file);
int a=is.read();
try {

View Replies View RelatedI 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

Expected Output:
Soberman
Actual Output:
----------------
Superman
Sober
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.

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;
}
I am trying to build up the alphabet character by character. Like:
a
ab
abc
abcd
Well as of now I can only print out the alphabet with my loop like abcdefg...z.. So here is the code I am trying to use:
public void loop4() {
char alph = 'a';
while(alph <= 'z') {
System.out.println(alph);
alph++;
}
}
I have the following code.
class A {
List<StringBuilder> list;
public void output(List<StringBuilder> objectToOutput){
try(BufferedWriter bw = new BufferedWriter(new FileWriter("temp.txt"))){
for(StringBuilder row:objectToOutput) bw.write(row.toString());
}catch(IOException e){}

Why don't the a's show up on the console? I put them in as part of the debugging process and now I don't understand why they don't show up in both places.

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.
