Capitalize Method - Return String With First Letter In Uppercase And All Other In Lowercase

May 19, 2015

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.

Convert The First Letter Of Every Word In A String To Uppercase?

Sep 20, 2014

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);
}
}

Textfield Lowercase And Uppercase

Feb 19, 2014

String sql = "SELECT * FROM user WHERE username =? and password =?" ;
pst = conn.prepareStatement(sql);
pst.setString(1, username.getText());
pst.setString(2, password.getText());
rs = pst.executeQuery();
if(rs.next()){
do somethig;
{

I have 2 textfield that take username and password, on the database thete is a user table

id username password name surname

1 test test test test

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?

How To Ignore Lowercase And Uppercase Letters

Oct 18, 2014

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] .....

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: ");

Capitalize Second Word Of A String

Feb 16, 2014

So the exercise I'm working on says to have the user enter their name and the program will output their name with the last name in all caps. i made it work BUT the only way i could figure it out was to ask for the first and last names separately creating two strings rather than one.

Of course I want to make it work how it's supposed to (with one string) so that I'm learning. I'm just having trouble conceptualizing how exactly (with varying lengths of names) to tell the program to only capitalize the second word... at first I thought create a substring beginning with the first letter of the last name and ending with the last...but again, therein lies the issue of varying name lengths.

is there a way to create a substring that beginIndex's at the first "space"? then i could just leave the endIndex parameter empty and it would take the whole word into a new string. and from there utilize toUpperCase to the new string?

Here's my code asking for the first and last names separately.

import java.util.Scanner;
class nameEcho {
public static void main ( String [] args ) {
Scanner scan = new Scanner( System.in );
String first;
String last;

Method Creation - Take A String With Duplicate Letters And Return Same String Without Duplicates

Nov 7, 2014

How can I write a method that takes a string with duplicates letters and returns the same string which does not contain duplicates. For example, if you pass it radar, it will return rad. Also i would like to know how can I Write a method that takes as parameters the secret word and the good guesses and returns a string that is the secretword but has dashes in the places where the player has not yet guessed that letter. For example, if the secret word is radar and the player has already guessed the good guesses letters r and d, the method will return r-d-r.

How To Get 1st Letter Of Input (String) And Compare It To Single Letter Before Insert To DB

Apr 15, 2014

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?

String Method To Return A Double

Jul 11, 2014

I'm having an issue with figuring out how to structure and call a method using a string prompt. My prof has given us specific methods to create, and the one I'm having issues with is blic static double getOperand(String prompt). What I have currently is this:

public static double getOperand(String operand1, String operand2){
Scanner input = new Scanner(System.in);
System.out.println("What is the first operand?");
operand1 = input.toString();

System.out.println("What is the second operand?");
operand2 = input.toString();
return operand1, operand2;
}

which is obviously not working. When I asked my prof he sent me this, "The String paramater in the getOperand() method is intended to have the prompt value that is passed to it. Within the method, the prompt is then displayed, what the prompt is asking for is input, and then returned to the method call.For example, if the method is public double getOperand(String prompt) within the method you would display the prompt, as in System. out. println(prompt), use the Scanner class to create an object, perhaps called input, and then use the input object to get the value asked for by the prompt. Once you have that value, which in this example would be a double, then return the value to the method that called it.

The call could be something like this: double value = getOperand("What is the first operand?");". But that only works a little. Clearly I'm missing something and no matter what I google, or how many times I read the chapter, I am just not getting this. Everything else up to this point has been easy. and I can create regular methods just fine, the menu method works, but I can't figure out this string method and all the rest build off this method.

Method Must Return Int Type - If Given Integer Is Strong Return A / If Not Return B

Sep 7, 2014

I want to use a method, which takes for example an int and also returns an integer. For example, if the the given integer is strong return a, if it is notstrong return b. How would you write that in a Code?

I want to use that in a more general way. I want to give a method mlong the value X of the type date and let it return an int. Type date consists of 3 int, one of them is the int month.

mlong should return an int depending on the X.moth. at the moment my code looks like this:

// File1:
public class date {
public int day;
public int month;
public int year;
}

// File 2:
public class monthlength {
public int mlong(date X) {
int t;
t = X.month;
if (t == 1 || t == 3 || t == 5 || t == 7 || t == 8 || t == 10 || t == 12)
{ return 31; }
if(t == 4 || t == 6 || t == 9 || t == 11)
{return 30;}
}

Return Array Containing All Strings That Start With Letter A

May 13, 2014

Write a method that accepts an array of Strings.  The method must return an array containing all strings that start with the letter 'A'.  

There must be no 'null' values in the resulting array.  The resulting array may be of size zero.

I don't think I am returning ALL the strings that start with A, just the last one of the for loop. Does this look somewhat correct?

public String[] startsWithA(String[] strings) {
String startsWithA = strings[0];
for(int i = 0; i < strings.length; i++) {
if(strings[i].charAt(0) == 'A') {
startsWithA = strings[i];
}
return startsWithA;
}
}

Java Method - Return True If String Can Be Found As Element Of Array And False Otherwise

Mar 17, 2014

I am new to Java and would like to ask how to do this question specifically:

Code a Java method that accepts a String array and a String. The method should return true if the string can be found as an element of the array and false otherwise. Test your method by calling it from the main method which supplies its two parameters (no user input required). Use an array initialiser list to initialise the array you pass. Test thoroughly.

Uppercase Character Counter In A String

Java Code:

userInput = JOptionPane.showInputDialog("Enter a string.");

My issue is that I would like the program to be able to function properly when spaces are entered into the string. As it is right now, I believe it is only processing the first string entered into the input box.

String Split Method - Return Array Of Strings Consisting Of Substrings Splitted By Delimiters

Sep 28, 2014

I am having a problem with the following code. It compiles and runs fine however my output is wrong.

public class SplitString {
public static void main(String[] args) {
String[] string1 = split("ab#12#453", "#");
String[] string2 = split("a?b?gf#e", "[?#]");
for (int i = 0; i < string1.length; i++) {
System.out.print(string1[i] + ",");

[code]....

The split method in the String class returns an array of strings consisting of the substrings split by the delimiters. However, the delimiters are not returned. Implement the following new method that returns an array of strings consisting of the substrings split by the matching delimiters, including the matching delimiters.public static String[] split(String s, String regex)For example, split("ab#12#453", "#") returns ab, #, 12, #, 453 in an array of String, and split("a?b?gf#e", "[?#]") returns a, b, ?, b, gf, #, and e in an array of String.

How To Return Values In Object Return Type Function (method)

Apr 2, 2014

How do i take input values for TwoDPoint (which are objects) and return it back in numerical values also print them.

When i create an object in main method and pass values to my function of return type TwoDPoint,it gives error:- found int,int need TwoDPoiint,TwoDPoint.

// Here is what i tried to do:

Created class TwoDPoint that contains two fields x, y which are of type int. Defined another class TestTwoDPoint, where a main method is defined.In the main method created two TwoDPoint objects.

Then I modified the class TestTwoDPoint and add another function to it. This function takes two TwoDPoints as input and returns the TwoDPoint that is farthest from the point (0,0).

Then I added another function to TestTwoDPoint. This function takes two TwoDPoints as input and returns a new TwoDPoint whose x value is the sum of x values of the input TwoDPoint's and whose y value is the sum of the y values of the input TwoDPoint's.

class TwoDPoint {
int x = 2;
int y = 4;
}
class TestTwoDPoint {
public static void main(String args[]) {
TwoDPoint obj1 = new TwoDPoint();
System.out.println(obj1.x);
System.out.println(obj1.y);

String Of Words - Getting First Letter From Each Word?

Mar 26, 2014

If I have a string of words and want to get a letter from each word (let's say the first), how do I code for anything past two?

For example, if I have North Atlantic Treaty Organization and I want to convert it to NATO I would do something like:

charAt(0) for N
charAt(x + 1) for A

But what do I do for anything past the second string? If I do charAt(x ++ 1) I get an error.
