My assignment about writing a java code which will convert a input java code to its respective class diagram, object, sequence , use case and activity diagram. I have worked only on restructuring of input java code till now and still I have lots to do.I'm looking forward for a reply expecting at least one code generating at least one UML diagram.

Here is my code:
public class ReverseString {
public static void main(String args[]) {
//quick wasy to reverse String in Java - Use StringBuffer
String str = "The rain in Spain falls mainly on the plain";
String revString = new StringBuffer(str).reverse().toString();
[Code] .....
The requirements: The program runs but for some reason it is not meeting the requirements. use the String method toCharArray and a loop to display the letters in the string in reverse order.
This is what I have to do:Write a program that takes a string of someone's name and prints it out last name first. Your program must use pointers, not array subscripts. You may use the available string manipulation functions if you find an opportunity.
Example:
"George Washington"
"Washington, George"
I am not sure how to reverse the name, I have been looking in my textbook and online and cannot figure it out. This is what I have put together so far, it does not run. At the end it says unnecessary return value.
import java.util.*;
import java.util.Scanner;
public class Test {
public static void main ( String [] args ) {
Scanner sc = new Scanner(System.in);
System.out.print("Enter name: ");
String name = sc.nextLine();
String lastname = "";
String firstname = "";
for(int i = 0; i < name.length(); i++) {
if(name.charAt(i) == ' ')
I am creating a recursive method to reverse a linked list in java. It works the first time when I call it, but I want it to work where I call it a second time and it reverses it to the original state. How can I get that to work with this implementation?
public void reverseList() {
System.out.printf("%-16s%-3s%n", "Name", "Score");
System.out.println("--------------- -----");
reverseList(first);
} public void reverseList(Node aNode) {
if (aNode != null) {
reverseList(aNode.next);
System.out.printf("%-15s%6s%n" , aNode.name , aNode.score);
}
}
I am trying to do this assignment but I can't get the needed output. Create a program that asks the user how many floating point numbers he wants to give. After this the program asks the numbers, stores them in an array and prints the contents of the array in reverse order.
Program is written to a class called ReverseNumbers.
Example output
How many floating point numbers do you want to type: 5
Type in 1. number: 5,4
Type in 2. number: 6
Type in 3. number: 7,2
Type in 4. number: -5
Type in 5. number: 2
Given numbers in reverse order:
2.0
-5.0
7.2
6.0
5.4
My code:
import java.util.Scanner;
public class apples {
public static void main(String[] args) {
Scanner reader = new Scanner(System.in);
double[] numbers;
System.out.print("How many floating point numbers do you want to type: ");

The users of our a enterprise Java based web application must access a third web application through simple HTML links and then navigate in the target application. But for security reasons and constraints the direct exchange between the browers of users and server of the other web application is not allowed. Our web application must retrieve the web page from the other application and must return it to the users's browser. Is there a convenient way to implement this requirement in J2EE ? In this case our web application must play the role of a simple reverse proxy, must request a target JSP page from other application and process it to rewrite the URLs contained in the HTML page, then send the response to user's web browser.
View Replies View RelatedI have the following double linked list and I'm supposed to order it descending (reverse) using the printInReverse() method; since the list orders itself ascending when the numbers are added, how could I order it descending in this method? Here's the code without implementing descending/reversing methods:
package test;
import java.util.Scanner;
public class MyList {
private Scanner userInput;
private Integer selectedOption;
private MyListElement firstElement = null;
private boolean exitRequested = false;
[Code] ....
I tried to declare a previousElement variable but I didn't figure out how I'd do that.
I want to develop a Java program that uses OpenScript APIs to test my applications. The OpenScript framework automatically creates the Java Code so I was thinking of either using this code or create my own using the APIs.
I tried both options using NetBeans but I'm getting errors everywhere starting with the library import. I'm pretty new to Java so I'm sure I'm missing a lot of things here. I pasted the code below from the OpenScript framework that want to use in a stand-alone file for your reference.,

you will be making four variables (2 primitive integers and 2 Account Objects). You will be following the steps detailed below. The challenge is to understand exactly what is happening and why. Start by coding the following two methods in a java file.
Start your main method with four variables: a, b c, d. a and by should be integer data, set them to be the values 10 and 20 respectively. Variables c and d should be Account Objects. The first account © is Ted, has $70,000 as his balance. The second account (d) is Joe, he has only $15,000 as his balance. Their account numbers are up to you to determine.Next, please print out the four variables: a, b, c, and d. Make sure that you label which ones are which. After you print these variables, please pass all four variables to a static method that you will create below. After you finish the method, please print out the four variables again: a, b, c, and d. Just as they were printed before the method.
Static methods: This method can be called whatever you want, however it will be public, static, and void. This method should take in four parameters: w and x which will be integers, then y and z which will be Account Objects.The first thing this method should do is to print out the four variables w, x, y, and z. This should be done in the same manner as you did in the main method. Next, change the first variable (w) to 15. After that, ted bought a new car. He now has only $20,000 in his account. Change the balance of y to be 20,000. Step three is to make a new Account Object named John, he has a balance of $10,000. Assign him to the variable z. Lastly, print all four variables again: w, x, y, and z.

This is what I have tried so far
public class ReverseStringTest {
public static void main(String[] args) {
Scanner in=new Scanner(System.in);
System.out.println("Enter String to replace:");
String temp=in.next();
System.out.println("Reverse String is:"+reverseString(temp));

But its not working it is return same string that is Input.
I am trying to reverse a string. Here is my code:

The program returns e instead of em
I'm trying to make a piece of code that writes a for Loop program using OOP. I need to create a class, name that class and have it contain several reverse methods and use a runner class to test it.So far this is the code I've come up with. Does it work or not?
public class loopDemo{
public static void main(string[]args){
String alphabet = "abcdefghijklmnopqrstuvwxyz";
public String reverse(){
char myBoi;
int myIta;
String tebahpla
for(myIta=25j i>=0 ji++){
tebahpla+= alphabet.charAt(myIta);
This code is supposed to convert a decimal base number to base 2, 8 or 16. It prints the number but it's supposed to be in the reverse order for example when converting 188 to base 16. it prints CB instead of BC.
package test;
import java.util.Scanner;
public class Test {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.println("Enter a positive integer.");
int number = input.nextInt();
[Code] ....
This is how the for loop works for the row,right?
for(int i=array.length-1;i>=0;i--)

}
I want to know how the for loop works for the column?
We recently upgraded to JDK 8. Since then, a section of code in a jsp file breaks. The code is this:
ArrayList all = new ArrayList();
final List tsd = timeSeriesBean.getTSData();
all.addAll(tsd);
Collections.sort(all, new Comparator() {
public int compare(Object o1, Object o2) {
TSData t1 = (TSData)o1, t2 = (TSData)o2;
int res = t2.getDate().compareTo(t1.getDate());
[code]....
The error message is this:
An error occurred at line: 65 in the jsp file: /TS/VerifyImportTSData.jsp The type new Comparator(){} must implement the inherited abstract method Comparator.thenComparing(Function, Comparator)
64:
65: Collections.sort(all, new Comparator() {
66: public int compare(Object o1, Object o2) {

View Replies View RelatedI have a new user on my website - it's password protected etc. and I'm just giving them the initial walkthrough. I have a java applet that plots charts and when he goes to this page he gets no chart and at the bottom of the pages there's a bar with the message "Internet Explorer blocked this website from installing an ActiveX control. What's the risk?" and then there's a button to say Install.
I said, it's just for you to permission running the java applet but his IT guy is saying that java doesn't trigger warnings about ActiveX controls so he's nixing the approval.
I have to write Scanner and Parser for the C-Code based on Java and obtain Abstract syntax tree(AST) . I am allowed to use tools like ANTLR, CUP. But i should be able to expand all macros in my code to its basic low level data type like int, boolean and whats the best approach?How to start initially?
