Is It Possible To Generate Javadoc From Class Files
May 15, 2007Is it possible to generate a javadoc from .class files?
View RepliesIs it possible to generate a javadoc from .class files?
View RepliesI've been tasked with checking over our product's javadocs. The product contains...I don't know how many hundred source files. I've began to notice a trend of similar small mistakes which I expect will be repeated throughout the entire product. So, in the spirit of developer's natural instinct to be efficiently lazy, I've started to wonder if there is an API out there which will allow me to run a quick check for common mistakes in our javadocs across the entire product.
Any API out there which can analyze javadocs? Ideally, I'd like to be able to write a quick and dirty program to recurse through the project structures and generate a small report on common mistakes in the javadocs (inconsistent phrasing, common capitalization issues, ect.). I can think of a couple ways of accomplishing this if I had an API which gave me access to a class's javadocs.
I would like to add comments at each method (like purpose, input params, return params etc.,) and at class level.
Should I do manually? or Can I use javadoc to generate something stuff? The thing is it's not like we're going to code now most of the project work is done. So, need to add comments for existing code.
In our product, we have many different of "roles". Some of these roles are defined in our dataload JSON and others are defined in our bootstrap SQL.
Throughout our code, we refer to specific roles by name. We want to provide some sort of documentation for these roles when we mention them in documentation, but we don't want to maintain multiple definitions/descriptions for these roles (ie: we don't want one for documentation and a separate one for execution).
Any way we can "expose" the role definitions to the documentation? The best thing I've got is adding some sort of "export script" to each generation of the javadocs, but I don't have a clue how, or if, that can even be done...
I have a string of variable tags (tag) filled with variables, and using a Scanner (scan) to manipulate and generate data dictionary add cards for each. The variables are delimited with new line character, and the variables are structured such that the actual name of the variable contains info as to its data type, size, etc. What I need to do is move the scanner to a particular point into the string then use .nextInt() or similar. I don't want to do this to the whole variable, just where I start it from. How can I do this?
E.g..
/* variables in String tag...
ANS_s20Tx12VDstr
ANS_:Tx67MSvis
ANS_zRx11MSctr
...
..
*/
Scanner scan = new Scanner( tag );
int ptr = tag.indexOf( "_" );
ptr++;
if ( Character.toLowerCase( tag.charAt( ptr ) ) == 's' )
// then start at the "_" character and grab the nextInt()
I need to store the data of a bunch of objects of a particular class in files in a predefined directory. Later, I want to get all the files from the directory and turn them into the objects again. Ideally, I'd like to have one file per object and have the files be human-readable and editable without too much difficulty. The class used by the objects will likely be subject to change in the future, as well. To keep things simple, all the data members are either primitives, Strings, or arrays of them. What is the best library/API to use to deal with this situation? Or should I write my own classes for these operations?
I read into serialization, but I read that it doesn't deal well with classes that are frequently modified. I also found articles on Preferences, but none of the ones I saw seem to explain how to best handle reading and writing to and from multiple objects, especially when I don't know a prior all the objects that were written to disk.
The problem is what to do when the source file for a class gets too big ( a judgment call for sure). Is it possible for one class to be defined in multiple files and if so how do you do it, and is it good practice?
I do see ways to refactor into a base class or move code into a helper class but sometimes the abstraction is cleaner as a single class that does a lot of stuff. My problem is how to organize a BIG class?
I'm writing a custom class loader to load some .jar file
public class IQJarClassLoader extends ClassLoader {
private String jarFile = "json-simple-1.1.1.jar";
private Hashtable classes = new Hashtable();
public IQJarClassLoader() {
super(IQJarClassLoader.class.getClassLoader());
[Code] .....
I receive this exception :
Exception in thread "main" java.lang.ClassCastException: org.json.simple.parser.JSONParser cannot be cast to org.json.simple.parser.JSONParser
Everytime, because i don't cast. Casting an object to a class with the same name loaded by different classloaders is no different than trying to cast.
I want to search for files using wildcards. After a lot of googling I found [URL] ..... I downloaded the .java files and put them in the same directory as my own java file. but now I don't know, how to include this java file.
View Replies View Related-I created the project with the checkbox "Create separate folder for sources and class files."
-I've tried running the program with the "mfq.txt" file in the root directory, the src directory, and the bin directory.
-I've even tried it in all three directories at once!
-I've also refreshed my project after each change in eclipse
-My error is the "FileNotFoundException" error
Here is the line giving me trouble
Scanner file = new Scanner(new File("mfq.txt") );
Where my code is wrong/where I should put my file? :tax:
We have a large applet based application with a current client-side minimum jar download size of ~4MB. If we put ALL of our class files into jars, that size will probably double. Most users only use a small portion of the class files for their particular tasks. Having ALL users download ALL the classes, compressed in jars, is extremely time consuming and a major problem after application updates due to the large number of users and the network load it would cause.
So after downloading some basic jars other needed individual class files are downloaded as and when requested by user. For signing applet, applet class files are moved to jar and this jar is signed with following attributes in manifest.
Jar file manifest:
Permissions: all-permissions
Codebase: *
Application-Name: XYZ
Application-Library-Allowable-Codebase: *
Trusted-Library: true
When applet is invoked from browser with JRE 1.7.51, there is a security blocked exception for individual files which are accessed from the signed applet jar. Why individual class files are blocked? Is it necessary to move all individual class files in a jar?
I'm having another issue. I have 2 java source files(see below). They are place in the same directory. How do I compile them using classpath?
I have already tried 1st attempt :
javac -cp com.companyname.interview.DuplicateReplace.java DuplicateReplaceTest.java [did not work!]
2nd attempt: javac -cp DuplicateReplace.java DuplicateReplaceTest.java [again, did not work!]
package com.companyname.interview;
public class DuplicateReplace { /* code */}
[Code] ....
I am currently building a Plugin system for an application and I wanted to add a little security feature.
I have read many tutorials on this and they basically all came down to the same answer:
"Its complicated: You need a custom class loader and security manager and ... and even then its still tricky"
So I thought, before I load the classes dynamically I will simply read the class files. Why bother with a SecurityManager or ClassLoader if I can simply whitelist all allowed classes and search for all illegal Class access before I even load anything.
I know that the simple deployment using only applet tags inside HTML causes severe security restriction for the applet on the client side. but can this simple HTML file contains .jar files inside the applet tags instead of .class files.
View Replies View RelatedSo I am trying to write the output of two different java class files to one txt file while the program runs. The file name is determined before the program is ran, through the command prompt as arguments. How can I get the second class file to edit the same txt file without running into compile errors.
For right now I'm just going to send everything that the second file outputs to a message String variable, so that the Main class outputs to the the text file. I still want to learn how to write to the same text file directly from the second class file.
import java.io.*;
public class Test{
public static void main(String[] args) throws IOException{
int x;
//create a new file internally called doc. But externally labelled the user input
File doc = new File(args[0]);
if (doc.exists()){

View Replies View RelatedIn a program I created, I'm using a text file that contains some texts needed for the program. The method relevant to this is something like the following.
private String wordgen(){

Random rand = new Random();
int low = rand.nextInt(400);
String fil="";

The program runs fine in netbeans project but once the jar is created it does not corporate with the text file. ("null" is returned) How can I attach text files to jar and exe?
I need to transformation the txt files into xml files, but each row txt files don't have same elements, for example the first book is composite one author
<books>
<book>Title</book>
<price>price</price>
<author>Author</author>
</books>
but the second book is composite two author
<books>
<book>Title</book>
<price>price</price>
<author>Author</author>
<author>Author2</author>
</books>
I would have the xml files with the number of authors variables, I can use JAXB for my problem?or not?
"which code is best for randomly generating integer 0 or 1". Haven't gotten my grade back yet but in reading these during the test I didn't think any of these would kick out both of those numbers, but there was no "none of the above" option on the test.This is exactly how it appeared on the test:
A) (int)Math.random() + 1
B) (int)(Math.random() + 0.2)
C) (int)Math.random()
D) (int)(Math.random() + 0.8)
E) (int)(Math.random() + 0.5)
I've tried all of them in the cs lab 100 times each and none of them generated both numbers. 'A' kicked out 1 every time. 'B,D and E' kicked out 0.2, 0.8 and 0.5 respectively each time, and 'C' kicked out 0. Did I just not run them enough times for the result to change or am I right in thinking there's a glitch on the test?
I have a large product with many maven projects, all of which can be hierarchically tracked back to the same parent. The projects have javadocs and whatnot.
Icommand line instructions (Windows 7) to generate the full API documents html on my local machine (of all the projects together). If there is a maven command for doing this from the CMD, more the better.
I need to generate a bar chart given the data that is in main. The relative performance of each sorting algorithm with respect to time, number of comparisons, and number of swaps for each data set (e.g., 50,000 –400,000 random integers). Each algorithm will have 5 bars corresponding to the 5 data sets. The height of these bars will depend on the performance of the algorithm for that data set.
I know how to write a bar with normal values like integers but for this I'm not sure because the values for instance comparisons and swaps are not given they are calculated. I just need to know what steps to go about doing that, you can even express them in pseudocode or even just explaining it I don't need the code, I think. Here is the main
public class Main {
public static void main(String[] args){
int t= 50000;
int t2=100000;
int t3=200000;
int t4=300000;
int t5=400000;

I am working on shopping cart application in which i want to generate selectonemenu dynamically for setting Item attribute from database.for eg, I have 4 tables item, attribute,attribute_value and mapping of this three. Now i want that I ask user to select attribute for item and than assign value.to assign attribute to item i created checkboxlist that is working perfectly then i want that selected attribute as label and their value appear inside dropdown.
i made to display but get confused when it comes to storing this value in database confused in red underlined place..This is without any dynamic generation but i think solution is dynamic component but dont know how code snippets:
<c:forEach items="#{itemManagedBean.allAttribute}" var="att">
<h:outputText value="#{att.key}" title="">
</h:outputText>

How would I get java to generate a random number from 0-2? all I've been able to find on random numbers is math.random which gives you from .0 to .10. you can multiply this by 10 to get 1-10 or by 100 to get 1-100 but how to make it so java will simply let me tell it the rand of numbers I want or get a random number in a range that is not a multiple of 10. and I can't seem to find anything about it anywhere.
View Replies View RelatedI am currently taking a class in the field. My assignment is to generate 6 unique random numbers using a "Do While" expression. I might be mistaken but doesnt the inner loop execute first and then it works its way out? With this logic I believe my code should work but then again its not.
public class DoLottery {
public static void main (String args[]) {
int max= 10;
int random;
int random2;
int random3;

I originally had output at the end but decided to comment it out to see if code would execute if I placed it every time the test was true.
I am trying to get random shapes to generate automatically. I was able to get just three shapes to generate but nothing random. When I added the random code now only the frame shows up and no shapes. I also keep getting an error with frame.setVisible(true). It says identifier expected. Here is what I have so far:
Main program:
import javax.swing.*;
import java.awt.*;
import java.util.Random;
public class ShapeGen {
public static void main(String [] args) {
//Create window and set title
draw panel = new Draw();
[Code] ....
This is the draw program to generate random shapes:
import javax.swing.*;
import java.awt.*;
import java.util.Random;
public class draw extends JPanel {
public draw(Color backColor) {
setBackground(backColor);

I have my code which will generate a random string using an ArrayList. However, I aso want to have it generate them in random lengths, not just using all the chars and numbers.
public static void main(String[] args) {
String[] CHARS = {"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","1","2",
"3","4","5","6","7","8","9","0"};
List<String> pass = Arrays.asList(CHARS);
Collections.shuffle(pass);
for (String chars : pass) {
System.out.print(chars);
}
}
