Program To Convert All Vowels To Capital Letter In A Sentence?
Jul 3, 2014
i am new to programming skills it may be silly question for experience but for me it's new thing. actually i tried a lot but i am facing problem when i trying to take input through Scanner. if i will take input a sentence directly as a string it's working . but when i am trying with Scanner the first word is showing next are not showing
public class Demo2
{
public static void main(String[] args)
{
String s1="hi how are you";
s1=s1.replace('a', 'A');
s1 =s1.replace('e', 'E');
s1 =s1.replace('i', 'I');
[Code]...
this is working properly.
but when i trying with Scanner i am facing problem.
public class Demo2
{
public static void main(String[] args)
{
java.util.Scanner scn= new java.util.Scanner(System.in)
String s1=scn.next();
s1=s1.replace('a', 'A');
I have a problem with functions connected to strings.
I have a random String, e.g. "Hello World!" and I have to change every capital Letter into a small letter and vise versa. This alone would be fairly simple, but I have to do it with two other strings.
lowercase= "abcde...z" and
uppercase="ABCDE...Z". Every small letter stands at the very same position as the capital letter, but in the other string.
There should be a letter for letter search in lowercase and uppercase for the letters of "Hello World".
How I could solve the task, however I need a way to search the first string, here "Hello World", according to position. A statement which does: "Give me the letter of position x". This found letter should be able to be stored in a variable or else be able to be used by another statement. And it should be compatible with a for lope.
I am trying to write a simple program that checks if a user's input has a specific letter using the ".contains" method but its not doing what i wanted to do. here is my code below.
import java.util.Scanner; public class secret { public static void main(String args[]) { Scanner sc; char hidden='a'; String guess;
I'm trying to convert the first letter of every word in a String to uppercase. I've managed to isolate the first letter of every word and then make it uppercase but I don't know how to replace it.
public static StringBuffer makeUpperCase(){ String str = String.valueOf(input2); for(int i = 0; i < str.length(); i++){ if(str.charAt(i) == ' '){ char var = str.charAt(i + 1); var = Character.toUpperCase(var); System.out.println(var); } }
Write a program that continuously asks for an alphabet letter, and stops when a non-alphabet letter is entered. Then output the number of upper case letters, lower case letters, and vowels entered ....
Ok, so I have to make a program that tells the user to type a sentence and at the end of the sentence a "." must be put to end the program. If a "." period is not entered, it must re-prompt the user to enter a period. On top of all this, the program has to count the number of letters in the sentence. I cant seem to get the while loop working and I cant find anywhere how to make a counter count the number of letters.
import java.io.*; class Sentence //The purpose of this program is to
Example : I have code and name but my code must start with the first letter of the inputed name if the 2 input is match it will be inserted into database
code = "A"001 name ="Angela" = success this will inserted into database
else
code ="B"002 name="Angela" =failed this will not inserted into database
else
code="A"003 name="Andy" =success still accepts the input cause they have diff code number
What I am thinking on this was compare the code the name? if == it will be inserted but how do i get the 1st letter of the input name?
SO for my project, we have to create a program where we input two four letter words, and using a list of words our teacher provided us and only changing one letter at a time, make the words match.For example, you input BALD and CALL and it would output BALD BALL CALLWe have to use recursion to do this, and I'm totally lost as to where to even begin.
I started using Java a couple of days ago, If you haven't guessed I want to see if the user is typing a full name or not, but I'm actually not too concerned with any more complexity than I mentioned in the title. It's ok if an input like "GLba b" comes out positive.
I wrote a java application that coverts number grades to letter grades. Here is what it looks like:
/java application to That corresponds the letter grade with the number grade import java.util.Scanner; //program uses the class scanner public class gradescore{
How to replace correct letter with the blanks in the program. Last method in program used to print correct letters.
import java.util.*; import java.io.*; public class Hangman { public static Scanner keyboard; public static final int MAXSIZE = 15000; public static final int NUM_GUESS = 8; public static final int WORD_LENGTH = 20;
Write a program that translates a number between 0 and 4 into the closest letter grade. For example, the number 2.8 (which might have been the average of several grades) would be converted to B. Break ties in favor of the better grade; for example 2.85 should be a B. Use a class Grade with a method getNumericGrade. why when I type .3 it tells me "Exception in thread "main" java.util.InputMismatchException" Or if there is an easier way to do this.
import java.util.Scanner; public class Grades { public static void main(String [] args) { System.out.println("Enter a number between 0 and 4"); Scanner input = new Scanner(System.in);
Write a program that will provide temperature conversions between degrees Fahrenheit and degrees Celsius. Provide a method that will take an argument representing a temperature in Fahrenheit degrees and return the equivalent temperature in degrees Celsius. Also provide a method that will take an argument representing a temperature in degrees Celsius and return the equivalent temperature in degrees Fahrenheit. Conversion formulas are as follows: F = 9./5. * C + 32, C = 5./9. * ( F - 32 ), where F = Fahrenheit temperature and C = Celsius temperature. You must prompt for input using the Input class methods that are provided as a download for this unit.
I have two questions, 1st is why won't I get an output from my program when I run it? 2nd is how do I prompt for input using the Input class methods downloaded? The downloaded files are in .class form, and won't show any output when I run them.My code is:
import java.util.*; public class temp { public static void main ( String [] args ) { Scanner in = new Scanner(System.in);
I'm working on creating the Binary to Decimal program . hat is wrong with this part of my code. Why does it not take you into the loop.
import java.util.Scanner; public class question5 { public static void main(String[] args) { System.out.println("Enter a Binary number. "); // collect Scanner keyb = new Scanner(System.in); //
A GUI program that allows user to enter their name and the program will convert it in number using array.
For example if i input "EUNISE" the output should be 521149195
Because the letter equivalent of
a = 1 b = 2 c = 3 d = 4 e = 5 f = 6 g = 7 h = 8 i = 9 j = 10 k = 11 l = 12 m = 13 n= 14 o = 15 p = 16 q = 17 r= 18 s = 19 t = 20 u = 21 v = 22 w = 23 x = 24 y = 25 z = 26
I am currently trying to count and display all the vowels in a set of given strings and can't seem to figure out what to do. I was able to print the line with the most vowels, but i also need to display them. The code is listed below and the given output.
public class Strings { public static void main(String[] args) { String sentence = "I am currently studing Computer Science." + "My name is whatever and I am orginaially from the state of Virginia." + "I recenetly separated from the Air Force where I served on the Presidental Honor Guard.";
[Code] ....
The output that i am getting is:
I am currently studying Computer Science . My name is whatever and I am originally from the state of Virginia. I recently separated from the Air Force where I served on the Presidential Honor Guard.
The line with most vowels is:
I recently separated from the Air Force where I served on the Presidential Honor Guard.
I am trying to write a program converting Fahrenheit to Celsius using a for loop. I get it to run and Fahrenheit goes to a hundred. My issue is that the Celsius just says 100 down the column and is not converting. I have tried messing with it, and can not figure what is wrong with it.
import java.util.Scanner; public class Controlstatement { public static void main(String[] args) { double F = 1.0; double Celcius = 100; System.out.printf("%s%20s", "Farenheit", "Celcius" ); for (int Farenheit = 0; Farenheit <= 100; Farenheit++) { F = Celcius * (Farenheit - 32 * 5.0/9.0); System.out.printf("%4d%,20.2f", Farenheit, Celcius); } } }
I am trying to make a translator program that will convert english to my custom binary. It works going from english to binary, but not going from binary to english.
import java.util.Scanner; public class Translator { public static void main ( String [] args ) { Scanner input = new Scanner( System.in ); System.out.print( "Would you like to convert English to Binary (yes or no)? " ); String answer = input.nextLine();
I just started programming yesterday, and I have been making little programs to learn some algorithms and the syntax of java. I tried making a program that could convert metric units into the American system. Whenever I try to compile the code, it shows up as an "incompatible type" error. I know this is probably a very obvious answer to most of you, but I can't figure it out.
import java.util.Scanner; public class MetricToAmerican { public static void main(String[] args) { Scanner scan = new Scanner(System.in); System.out.println("fWhat measurement would you like to convert into US system? celsius, meter, or kilogram ");
Write a GUI program to convert all lowercase letters in a string to uppercase letters, and vice versa. For example, Alb34eRt will be converted to aLB34ErT.
