Read Line Of Text And Output Text First In All Uppercase And Then In Lowercase Letters
May 29, 2014
Write a program that reads in a line of text and then outputs that line of text first in all uppercase letters and then in all lowercase letters.
INPUT and PROMPTS. The program prompts for a line of text as follows: "Enter the text: " and then reads in an entire line of text as a String .
OUTPUT . There are four lines of output . The first line is "The text in all upper case is: ". The second line is the line that was read in, displayed in all uppercase. The third line is "The text in all lower case is: " and the fourth line is the original line that was read in, displayed in all lowercase.
CLASS NAMES. Your program class should be called ShoutAndWhisper.
This is what I have so far:
import java.util.Scanner;
public class ShoutAndWhisper
{
public static void main(String[] args)
{
Scanner scannerObject = new Scanner (System.in);
System.out.println("Enter the text: ");
scannerObject.next();
System.out.println("The text in all upper case is: ");

I am checking how to do following task.
01. pickup the selected text file and read the line by line and output the text in to visual text pane.
what i did:.
01. I wrote code that read the text file and output in to jave console/ also some of the interface.
the code read txt file:
Java Code:
String fileName = "C:/Users/lakshan/Desktop/lawyer.txt";
File textFile = new File(fileName);
Scanner in = new Scanner (textFile);
while(in.hasNextLine()){
[code]....
so it will read any text file dynamically and output to the text pane in interface. I think scanner code must be execute after the select the file from the browser and set the scanned result in to variable. then later out put the var as string in some jswing component?

I have made a program, where the user types in a letter M, C or I to identify their major, if the user types m, c or i, my code does not work.
How could I make my program ignore if the letter is upercase or lowercase? My code is posted below. Can I do this in any easier way then adding this type of code for each lowercase letter?:
Java Code:
if (s.charAt(0) == 'm')
System.out.print("Mathematics "); mh_sh_highlight_all('java');
My current code:
import java.util.Scanner;
public class c4e18 {
public static void main(String[]args){
Scanner input = new Scanner(System.in);
System.out.print("Enter two characters: ");
String s = input.nextLine();
if (s.charAt(0) == 'M')
[Code] .....

I am working on a personal project and want to create a text editor to write my code. I am wondering how could I read the last input from the user and if say it was an open curly brace {, then like netbean's my editor will supply the closing curly brace. My java experience is limited but I have tried to read key board input and a few other options that did not work.

So I'm trying to read 11 values from a text file, each value on a separate line. The first value I use as loop control to run through calculations on the other ten and finally output both the numbers and the calculations to the console and an output file. I'm not getting a compiler error or a runtime error but my loop seems to stop after reading the first line. It also doesnt seem to be writing to my output file but does create it when I run the program. This is what my text file looks like
10
150.4
88.4
-3.14
499.4
799.4
1299.8
0
1900.2
901.7
4444.4
This is what my program looks like
import java.util.*;
import java.io.*;
public class assignment7scratch
{
Toolkit_General toolKit = new Toolkit_General();
public static void main (String[]args)throws IOException
[Code] .....
so I dont get an error but this is what my output looks like
----jGRASP exec: java assignment7scratch
This program reads a list of values representing number of miles driven by individuals. It will output the dollar amount their rental cars cost.
Number of miles traveled on the left as well as amount reimbursed on the right
-----------------------------------------------
Miles Driven Amount reimbursed
150.427.072
----jGRASP: operation complete.
it also doesn't write anything to my output file, though it does create one.

people put username and password to the textfield like test test and they logon,but when they write username = TESt and password = teST they can logon too,there is no TESt user on the database or teST password, is the textfield making lowercase all text. or pst.setString(1, username.getText()); is this code changing the text?

I'm using JBoss 7.1.1.Final. I'm writing a Spring 3.1.1.RELEASE web application and have a massive amount (~5MB) of text output to send to the browser. I would like the browser to display the output as it is generated, but right now, the browser only displays everything after the servlet's doGet method completes. Here's my method …
@RequestMapping(value = "/mymethod", method = RequestMethod.GET)
public void refreshOrders(final HttpServletResponse response) throws IOException
{
execute(response, myWorker);
}
private void execute(final HttpServletResponse response,

I set my buffer size to be 1K but that doesn't do anything.

I am trying to read a text file into Java and split the text into tokens. Eventually I want to be able to count the number of instances of a specific word. However, at this point, when I run the file, all I get is the location of the file rather than the text in the file.
import java.util.*;
import java.io.*;
public class textTest3 {
/**
* Prints the number of words in a given file

I'm trying to create a private method called capitalize() which takes String nameModel in any uppercase/lowercase combination and returns it with the first letter uppercased and all other lowercased. E.g. "stePHeN" returns "Stephen" . This is what I've written so far:
private String makePrettyString(String modelName) {
if (modelName ==null) {
return null;
}else if (modelName =="") {
return "";
} else{
return modelName.substring(0,1).toUpperCase() + modelName.substring(1).toLowerCase();
}
}
Unfortunately it doesn't work and it still returning me the String modelName in its original uppercase/lowercase combination.

I'm trying to print the information entered into my TimeClockApp to a text file named timeclock.txt. Everything is writing to the text file, except instead of adding each part of the run through the app to one line, it is saving each part on a separate line like this:
i
3
2014/06/08 15:32:29
To ensure that each run through the time clock is recorded on a different line in the text file, I want it to add each item like this instead:
i 3 2014/06/08 15:32:29
I have tried to execute the
out.println(timeClock.get(i)); line as out.println(timeClock.get(i) + " "); and out.println(timeClock.get(i) + "
");,
but have had no luck in fixing this problem. My current code that writes the information to the text file is as follows:
// write items to timeclock.txt file
try {
// open an output stream for overwriting a text file
PrintWriter out = new PrintWriter(

how to use SAX Parsers. I've looked at a few tutorials and have the generals down. I have an xml file that the parser is trying to read. As you see below, at the start of each element, I add the tag to an arrayList of the tags. I create a stringBuilder to capture the text between tags, this won't work unless it occurs at the end of an element. If it occurs at the start, it never gets the chance to read the text.
This is where the problem occurs. For nested tags, like project, it reads the last nested tags' text and stores it in the text arrayList. Project may be the first indexed tag in the tags arrayList, but project's text is the fourth indexed element of the text arrayList. So when my test print the arrayLists by index, it gets thrown off. I want over tags to store a blank space in the text array, and at the same index of the tag its associated with. How would I do this?
I've tried overwriting the text arrayList, but couldn't get my logic thought out for how to determine if a tag was nested. I always ended up overwriting blank space to each element.

How to output text to a file, so I had to do my own research on google, but the results I found were confusing. I finally got my code to write to a file, but I cannot figure out how to append a new line. I know what part of the code is incorrect, but I don't know how to fix it. here is what I have right now:
import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Paths;
import java.util.Scanner;
public class highscore {
public static void main(String[] args) throws IOException {
[Code] ....
I can see the last two lines are telling the program to overwrite the first input with the second. Of course if I pick a different file name for the second output, I get another file with the second input, but I need to learn how to append as well.

I have a code that imports a text file [URL] .... and has a variety of methods for sorting through it. The file is structured differently when loaded into the environment, as each line begins with a movie and lists all of its actors. Each line has a movie title, then its release date in parentheses, and then the actors in the movie all listed and separated by slashes (Ex: /lastname 1, firstname 1/lastname 2, firstname 2/etc.....
Well I tried to create a method to search all the actors in the file for an inputted word and return the ones that have that word somewhere in their names. I managed to get it to work, but the code only runs for one line of it. How should I get this to do what its doing, but for EVERY line?
Code is here: [URL] ....
