Letters Of A String That Occur From Second Half Of Alphabet
Feb 11, 2014
Write a method named secondHalfLetters that accepts a string as its parameter and returns an integer representing how many of letters in the string come from the second half of the alphabet (that is, have values of 'n' through 'z' inclusive). Compare case-insensitively, such that uppercase values of 'N' through 'Z' also count. For example, the call secondHalfLetters("ruminates") should return 5 because the 'r', 'u', 'n', 't', and 's' come from the second half of the alphabet. You may assume that every character in the string is a letter.

So my goal is to use the graphics class to draw this shape: [URL] ....
so far I've managed to draw the bottom half, but now I want to utilize the copyArea() method to flip the bottom half and copy it to produce the upper half of the shape: [URL] ....
and this is what I wrote to produce the bottom half:

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.

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.

I want to make a method that takes a word and then checks if the word can be created from available letters. For example, if a word "johnson" can be created by using letters "jashoqwnon".
Now my goal is to make sure that if available letters contain a letter from the word, that letter is put into a String called result and then erased from the list of given letters. So, "johnson" and "jashoqwn" would produce the result "johns" and leave "aqw" unused.
Now the problem that I am facing is that I can't get Java not to use the same letter twice. So "johnson" and "jashoqwn" still gives "johnson".
I've tried everything in my power but I am missing something. Here is my code.
public static String makeAWord(String word, String letters){
String result = "";
for(int i = 0; i < word.length(); i++){
for(int j = 0; j < letters.length() ; j++){

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.

Here is the problem:
Start with the tree.java program (Listing 8.1) and modify it to create a binary tree from a string of letters (like A, B, and so on) entered by the user. Each letter will be displayed in its own node. Construct the tree so that all the nodes that contain letters are leaves. Parent nodes can contain some non-letter symbol like +. Make sure that every parent node has exactly two children. Don’t worry if the tree is unbalanced. Note that this will not be a search tree; there’s no quick way to find a given node. You may end up with something like this:
It also says all Letters must be Leaves
Now I had it almost similar to that picture, but it wasn't right. So ive been working on it but im getting some very strange (and frustrating) output from the following methods.
Ive included the display method just for reference. The book told me to use it so I haven't edited it. I believe my main issue is with my (incomplete) insert() method. The output goes into an infinite loop despite having a return statement break the while loop when a character is inserted.
The way I see to solve the problem is just add a (+) whenever a new subtree needs to be created. Say I add A and B, then it first creates a subtree at the root with a (+) and afterwards lists A and B as its leaves. If I insert a C, it should be able to simply move to the right child of the root and deposit the C there.

I want to create a java program that can be encrypt-decrypt alphabet from characters . Which is the shifting of the alphabet is starting from the the first character to increase 4 and 5 increased in the second character, increasing 6 at the third character, and so on..
Then when one of the characters increasement is more than the ascii code of 'z', that character will decrease from the variable i from the loop. This is the output of the program that i want:
Encryption:
Plain text: "abcz"
Cipher text: "egiz"
Decryption:
Cipher text: "egiz"
Plain text: "abcz"
This is my code for now:
package -;
public class - {
public static void main(String[] args) {
String enkripsi = "abcz".toLowerCase();
String dekripsi = "egiz".toLowerCase();
[Code] ....
What's wrong with my code? It won't work. Specially in the decryption.

I have an encoder that will shift the character of a string X places. Im trying to account for the possibility of the shift being larger than alphabet array length. I've come up with the following, but I still get an ArrayIndexOutOfBounds Error and it never gets past the if statement.
private String encryption(char charArrayElement) {
String [] alphabet = {"A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L",
"M", "N", "O", "P", "Q", "R", "S", "T", "U", "V", "W", "X", "Y", "Z"};
String str = String.valueOf(charArrayElement);

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 can't figure out why my code doesn't work. My task is to replace for example ä=>ae, using this method String.charAt(int index). So here is my code:
public class pich {
public static void main(String[] args) {
String text = "Die süße Hündin Leica läuft in die Höhle des fülligen Bären "+
"Iliyan (ein Übergrößenträger), der sie zum Teekränzchen eingeladen hat."+
" An ihrem Öhrchen trägt sie modisch eine Ähre.";
String textOhneUmlaute = "";

when I launch my code I get the same String and nothing has changed

While using generics, are there cases when ? wildcard cannot be replaced with letters [A-Z]? So far , I was able to find only one case, it is when you want to have field pointing on generic instance without making class generic.
class OneClass {
private LinkedList<?> myLL;
}
In case above, as I understand, you cannot use [A-Z] without generalize OneClass. Are there any other cases, when there is no way except to use ? wildcard instead of letter [A-Z]?

I have devised a simple program that reads a file and then adds up al the integers in the file and print the result, for example if the file had the numbers
1 2 3 4 5 6 7 8 9 10
then the program would print 55
However i have trouble when non integers are put into the file for example if it was
1 2 3 string 4 5 6 test 7 8 9 10
then i get:

My professor is a man who enjoys making his students form large, but often simple symbols with smaller letters. That might not have clarified much, so let me demonstrate:
VVVVVVV
VVVVV
VVV
V
Or...
X X
X X
X
X X
X X
Or lastly...
O
O O
O O
O O
O
My problem is, that I've always been bad at figuring out the logic behind these.
I can kinda' see it (somewhat) in my head though... I'd need a double for-loop which depend on the sizes, one that monitors the spaces and one that monitors the symbols, with some conditionals in there. How to make symbols like this, using letters, in Java.
