What I am trying to do is extract the digits from between the words 'deal' and 'of'. I was wondering if this was possible to do with a regular expression or if I should just use a scanner.
UNIQUE Passive - Cleave: Basic attacks deal 20% to 60% of total Attack Damage as bonus physical damage to enemies near the target on hit (enemies closest to the target take the most damage).
Is there a regular expression that I could use in order to extract the '20' and the '60' from the above text. Below is what I have tried, but does not work.
(?<=deals)(d+(?=%))(?=of)
just to make a clarification, these numbers will not be the only numbers and the strings themselves will change. Everything can be considered a variable. The only constants between each string would be the words 'deal' and 'of'. The regex pattern "d+" is not a viable expression for my case
Goal is to: Write a program that prompts the user to input an integer and then outputs both the individual digits of the number and the sum of the digits.
First I don't know where I made mistakes here, and the only error it finds right now is that str2 was not initialized and I cannot figure out where/when to initialize it.
import javax.swing.JOptionPane; public class DigitsAndSum { public static void main (String[] args) { String str1; String str2; int int1 = 0; int int2 = 0;
Write a menu driven program that either accepts words and their meanings, or displays the list of words in lexicographical order (i.e. as in a dictionary). When an entry is to be added to the dictionary you must first enter the word as one string, and then enter the meaning as separate string. Another requirement - from time to time words become obsolete. When this happens, such word must be removed from the dictionary.
Use the JOptionPane class to enter the information.
Use the concept of linked list to carryout this exercise. You will need at minimum the following classes:
- A WordMeaning class that hold the name of a word and its meaning. - A WordMeaningNode class that creates the node of information and its link field. - A WordList class that creates and maintain a linked list of words and their meanings. - A Dictionary class that test your classes.
For the output, the program should produce two scrollable lists:
- The current list of words and their meanings. - The list of the deleted words. You need not list the meanings, just the words.
So far, I have everything coded except for the remove method, and I am not sure how to code that. I coded the add method already, but now I don't know where to begin with the remove method in my WordList class. My classes are below.
WordMeaning Class:
public class WordMeaning { String name; String definition; WordMeaning(String t, String d) { name = t; definition = d;
So, let's say I have a pdf that looks like an exam or anything that has answer choices and an oval to fill in.
So, if I want to create a program that fills in some of those ovals, I would first need to find the coordinates? I can use something like gimp?
And once I have those coordinates, what do I do? Like do I extract the oval image and replace it with a filled in one? Is there a library that lets me do this - also lets me set the size to make sure the new filled in oval image is the same size?
I have table data I'm trying to read . However one column is populated with the word "null". I guess java does not like dealing with the word null and throws errors.
When I try a block like : if ( rsrow.getString(insCol) = "null") {
I get and error .
If I try :
cmp = rsrow.getString(insCol);If I try:If I try: if (cmp = "null") {
I get an error
If I try to use a replace function like:
System.out.println(cmp.replace("null", "0"));
Just to see if replace works I get and error.
What is the BEST way to replace this string value with something like "0" when I come across it with out jave throwing an error? I want it such that every time I come across the word "null" I can repalce it with "0".
how can I extract data from two different files but produce one output. For example, the first three columns are from text_file_1 and the last column (the last foruth column of the output) is from text_file_2.
I'm trying to make my first servlet, however since I have only installed the Java SE, the javac compiler is complaining about missing packages (javax.servlet.http...)
I've realized now that I need javax.servlet jar or class files from Java EE, but after downloading java_ee_sdk-7u1.zip from Oracle here I'm not seeing any .sh or java_ee_sdk-7-jdk7-macosx-x64.sh installer (which I saw mentioned elsewhere). The oracle page only instructs to unzip the downloaded file, and searching for javax.servlet only reveals a few files which I'm not sure what to do with:
I'm looking to get two values from this string. I have tried re formatting and with little success. I read this in from a text file and then tried the below code to extract it. I have also tried
{Deposit=100.00, Fees Paid=5.00}
I am just looking to get the 100.00 and the 5.00. I tried using this code below but it separated it into Comma and put it in an array which is probably what im not looking for.
[code] final Pattern pattern = Pattern.compile("[=st]"); final String[] result = pattern.split(st2); System.out.println(Arrays.toString(result)) [code]
I am supposed to read in a file and extract the data. I am trying to add a Long into an Array that I initialized. So this is how my method looks like :
Java Code:
public void readOSMWay(File osm){ try { Scanner output = new Scanner(osm); while(output.hasNext()){ String line = output.nextLine().replace("^s+",""); if(line.startsWith(" <way")){ Road way = new Road(line,true);
[Code]...
I am having problem with the else if block. I am supposed to add all the Long values into the array.
error: Java Code: The method add(Long) in the type ArrayList<Long> is not applicable for the arguments (String) mh_sh_highlight_all('java');
I should do, for my academic project, draw from a java project some information, for example, the class name and the relative method, and for each class even the package name where the class is. The information found must be saved an XML files...
consider this statement from a jsp file(there are many more statements like this in jsp file..) Statement -
<h:dataGrid something styleclass="styleclass1" something1 onClick="event" something2 <% this is a scriplet tag %> something3 style="style1">
<h:output text>hello i am text</h:output text> </h:dataGrid>
What I want is to extract(and store it somewhere) the part from "<" to ">" where:
< - is the one in "<h:dataGrid" > - is the one in "style1>" and not the('>') one that appears in the end of "</h:dataGrid>" or "<h:output text>" or "</h:output text>"
Problem is the text b/w && is in multi-line...&& there are scriplet tags in between them.. so i don't know how to extract this particular string.. i tried using using some regular expressions but couldn't find the exact one..
(this was just an example && instead of this "" tag it can be anything like again in this line :
<h:output text>hello i am text</h:output text>
I want to extract the string from "<" till ">" where :
< - is the one in starting of "<h:output text>" > - is the one in ending of "<h:output text>" and not the one in "</h:output text>"
However the difference b/w this example and the above mentioned one is that this one is not multi-line and doesn't contains any scriptlet tags)....
I will be developing a change and would like to know how can i parse a mail header in OBPM using java.
I want to get the message id, date and time the email recieved and email size.
Our code is already fetching the attachment of the email using the following syntax.
mailAttachments = mail.attachments;
I tried creating a variable like mailHeaders = mail.headers, would you know how can i get the details i want by parsing the variable? so far I wasn't able to check what mail.headers return as i'm currently having issues running our code locally due to DB connections.
I need to break it and #numbers in braces are assigned to string array and they should cal by one by one. similarly next level on calling #166 same operation should perform
{#166=ADVANCED_FACE(",(#165),#129,.F.);}
like this 8 levels were there, finally at each level the Calling number should display in JTable.
I do have a quick question about string manipulation. You see I've been given a simple exercise that involves asking the user to input a number between 1,000 and 999,999 and displaying the result. Simple enough, but the caveat is that if the user keys in the comma, say 24,000 instead of 24000 for example, the program is not to display the comma. I don't see how to do this without an 'if' statement. The book says the 'if' is not necessary but does offer this hint: "Read the input as a string. Measure the length of the string. Suppose it contains n characters. Then extract the substrings consisting of the first n-4 characters and the last three characters."
What good is n-4 going to do if the string's lengths varies?
Here's what I have written thus far:
import java.util.Scanner; public class P13 { public static void main(String[] args) { Scanner in = new Scanner(System.in); System.out.print("Please enter a number between 1,000 and 999,999: ");
my idea is auto recognize when i put image like survey and that survey has shape box and it random area location and some shape box also character and number and can generated data that recognize in csv file.
I have to seperate a number 9876 to 6 7 8 9, to 9 8 7 6. I need to know how to sum the digits. I have gotten to this point ::
import java.util.*; public class week4program { static Scanner console = new Scanner (System.in); public static void main(String[] args) { int num1; int digit; int sum = 0;
[code]....
To this point its gives me the seperate integers. OK but how do I get the variable integers into seperate containers and then add them up?My assignment is to do that, and what I have above gets me to where I have seperate digits, but how do I catch them into seperate entities to be added to a sum?
I have it so it gives me the sum of any digit, i just cant figure out how to get only the odd digits to add up. for example if I were to type 123. The odd numbers = 4 but using this program i get 6
class SumOfDigits { public static void main(String args[]) { int sum = 0; System.out.println("Enter multi digit number:");
import java.util.Scanner; public class CubesSum { public static void main (String [] args){ int input; System.out.println("Enter a positive integer:"); Scanner in = new Scanner(System.in); input = in.nextInt();
As you can see I'm using a while loop. For part B which is to modify to determine what integers of two, three, and four digits are equal to the sum of the cubes of their digits. So for example, 371 = 3³+7³+1³. How to do it? I need to wrap a for loop around my while loop...
Make a program which takes input from the user (6-digit number) and check how many times each digit gets repeated in the number. Java GUI was used (Netbeans 6.5.1).This is my code. I took the input via a JTextField named tf and displayed the output on JTextArea ta.
- arrays not used as we haven't studied them yet
int num= Integer.parseInt(tf.getText()); int no=num; if(num<100000) ta.setText("Invalid Input. Please Enter 6 digit number"); int n1= num%10; num=num/10; //stores last digit
[code]....
How do I omit the last 5 lines? This problem occurs whenever I input a digit with any recurring digit.What changes/additions should I make?
The following code splits an integer into separate digits. It then adds 7 to each of those digits, and then finds the remainder when the result is divided by ten. To do this it uses the Modulus operator.
public class manipulateIntegers { public manipulateIntegers() { System.out.println("Enter a four digit Integer"); String y = System.console().readLine(); int[] list = new int[5];
[code].....
I understand completely about what modulus does vis-à-vis fetching the remainder, but I don't understand why using the modulus operator gets you each digit individually?
for example, this snippet splits the digits of an integer - but how??
int number; // = some int while (number > 0) { print( number % 10); number = number / 10; }
and why does number have to be reassigned as number / 10?
