Program Prompts For A Line Of Text
Jun 2, 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.
[import java.util.Scanner;
public class ShoutAndWhisper
{
public static void main(String[] args)
{
Scanner scannerObject = new Scanner(System.in);

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?

So i need to write a program that prompts the user for 3 double numbers x, y, z that outputs 2x^3 + 3y^5 + 3x^3y^2 +xyz with
(1) 4 digits precision
(2) with a ',' to separate thousands
(3) all digits of the result including the precision are put to 20 positions (from right to left)
I am not really sure what it is suppose to look like or how to start it.how to mix Math.pow with multivariable and printf.

so I had to make a program that prompts the user to enter a loan amount and the years for the loan and I have the conversions and everything my only issue is that when the chart pops up it just looks like a bunch of numbers and its missing the column headers
for example
Interest Rate Monthly Payment Total Payment
import java.util.Scanner;
public class InterestRate {
public static void main(String[] args) {
double monthlypayment = 0;
double totalpayment = 0;
Scanner input = new Scanner(System.in);
System.out.println("Enter Loan Amount");

Write a program (TwoIntegers.java) that prompts the user to enter two positive integers and prints their sum (by addition), product (by multiplication), difference (by subtraction), quotient (by division), and remainder (by modulation). When the user enters 5 and 3, the output from your program should look exactly like the following:
Enter two positive integers: 5 3
The sum is 8.
The product is 15.
The difference is 2.
The quotient is 1.
The remainder is 2.
import java.util.Scanner;
public class TwoIntegers {
public static void main(String[] args) {
System.out.println("Enter two positive integers: ");
Scanner userInput = new Scanner("System.in");
int integer1 = userInput.nextInt();
int integer2 = userInput.nextInt();

Write a Java program that randomly generates a five-digit lottery number and prompts the user to enter a five-digit number. Each digit in the number is in the range between 0~9. The program should determine which prize the user wins according to the following rule:
• The user wins the first prize if the user input matches all five digits in the lottery number in exact order.
• The user wins the second prize if the user input matches any four digits in the lottery number in exact positions.
• The user wins the third prize if the user input matches any three digits in the lottery number in its exact position.
• The user wins the fourth prize if the user input matches any two digits in the lottery number in its exact position.
• The user wins the fifth prize if the user input matches any one digit in the lottery number in its exact position.
and here is my code. I cant get it to print the right statements.
import java.util.Scanner;
import java.util.Random;
class Hw5 {
static int getPrize(int g1, int g2, int g3, int g4, int g5,
int u1, int u2, int u3, int u4, int u5) {
//code for determining the prize comparing (g1, g2, g3, g4, g5) to (u1, u2, u3, u4, u5)
if (u1 == g1 && u2 == g2 && u3 == g3 && u4 == g4 && u5 == g5)

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

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] ....

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.

So basically, if a line in a text file contains a certain string, that specific line will be deleted. It should probably be similair to this method?
Java Code:
/**
* Replace text.
* @param replace
* The text to replace.
* @param replaceWith
* The text to replace with.
*/
public static void replaceSelected(String replace, String replaceWith) {
try {
BufferedReader file = new BufferedReader(new FileReader("data/replacer.txt"));

I am having issues insert each line of the simple textfile into a specific varible I want it to go to. For example my text file is ordered like this
Dallas
78 F
North, 15 mph
dallasimage
Denver
29 F
South, 10 mph
denverimage
and I want Dallas in city variable, 78f in temperature variable, and so on until text ends, at the moment is all goes into city variable, it all prints from there! I tried inserting it into an array but it would read all the lines previous to it in addition to reusing readline and all failed.

I'm currently learning Java and have been set an assignment that requires me to do the following:
Write an application that reads in a line length followed by individual lines containing text. No input line will be longer than the read in line length. In the text lines each word will be separated by a single space. The lines of text to be reformatted and then output so that the output lines of text have straight left and right margins. The last printing character in each line will be at character position (line length). In the text output the character '.' is to be used to represent the space character.

I'm trying to take this task on, but I'm unsure as to what exactly I'm supposed to do with part of it. For one of the methods I need to "work out how many extra spaces will need to be added to make the line width characters long.", how would I go about doing this?

I have a large text file of 1 GB size. I need to print the line when a matching word is found in a particular line. Below is the code I am using. But if there are many lines that has the matching word, it's taking lot of time. Any solution to print the lines much faster.
Scanner scanner = new Scanner(file);
while (scanner.hasNextLine()) {
String line = scanner.nextLine();
if(line.contains("xyz")) {
System.out.println(line);

I have a program that runs in the terminal (I use Ubuntu). It asks the user for a String, does something with it, and terminates.It works in the NetBeans terminal, but not outside of it. Specifically, regardless of what I input, it doesn't continue with the program. I enter something, press enter and it just goes to the next line in the terminal.
Java Code:
Scanner scan=new Scanner(System.in);
System.out.println("Enter the music directory:");
String path=scan.nextLine(); mh_sh_highlight_all('java');
how do I pass in arguments when I run the program (still in Linux)? Is there a way to check if the program was launched from the terminal or not?
