I have been assigned to write a program that has a user input random numbers then the program is to sort them in different ways. I have the coding for the different sorts but, I have an error saying that I am missing a return statement in the "Bubble" method. I am trying to return "arr[i]" in the "for loop" which gives me this error, and when I try to take the "return arr[i]" outside of the "for()" loop the error reads the it cannot locate variable "i".

I've created a constructor in bean and put an value to my string after doing so all started to work properly. I am trying to get my application to work but no luck so far. I have looked for similar issues but although there were similar I've got no luck in fixing mine.

I'm working through Head First Java, and I'm struggling with the chapter 6 magnet exercise on page 161. I've checked my answer countless times, and it appears to match the book's code, but when I try to run it on my computer I'm getting an error. It says:
error: <identifier> expected
System.out.println^(" "); and
error: illegal start of type
System.out.println(^" ");, both for line 32.
I cannot seem to figure out what is different about my code!!

So I'm trying to check if the new coordinates vs original coordinates are diagonal and 1 line further, and if there is a piece there(getNum()) if it's 2 lines further, so I'm trying to return a boolean value then.
so if it's the first if, it returns true, if it's the 2nd it returns true, then I say else for all other scenario's, and return false there, but my compiler says my method is missing a return statement.
public boolean check(int[] d) {
int x,y;
x = loc[0][0];
y = loc[0][1];
int sx = d[0];
int sy = d[1];

Edit: used a local boolean and returned that after my if's.,

I am obviously new to programming and Java so I set myself the goal of creating a very simple auto type style of program so it gets the users input and relays it out again but potentially to another window (I am currently testing to notepad). The reason I am trying to make it is because i thought it could be quite simple and I can build on it as a project to make it better.
The issue I am having is that it outputs the first character to the window I am selected (again testing into notepad) but then stops and doesn't output anything else. I tried to figure out what was going on by putting a System.out.println(arr[6]); after the delay method but it just output a line so almost like what I was putting into the array was only storing the first character of the string? I cannot figure out why that would be...

Why do I see many exceptions for one missing file on the stack trace ? My guess is, where ever that file or methof is being called , all of them will throw exceptions. So, where do I find the root exception, first one which is thrown OR the last one ?
java.io.FileNotFoundException: c: emppw.txt (The system cannot find the file specified)
at java.io.FileInputStream.open(Native Method)
at java.io.FileInputStream.<init>(FileInputStream.java:120)
at java.util.Scanner.<init>(Scanner.java:636)
at com.rbc.ReportDriverRunner.getPassword(AuditReportDriverRunner.java:39)
[Code] ....
In the above stack trace, "java.io.FileNotFoundException: c: emppw.txt (The system cannot find the file specified)" is the root cause (Assuming there is only one error which causes code to fail) ? Is the first one cause of failure whch then cascades failure of other methods ?

I am very new to EJB. Started with Session bean demo which was working fine. (created a jar file which had EJB and a WAR file which had servlet). But face some issues when created MDB . (For that also created a JAR file which had EJB and a WAR file which had servlet).
I have used @JMSDestinationDefinitions({
@JMSDestinationDefinition(name = "java:global/jms/mySalutationQueue", interfaceName = "javax.jms.Queue")
}) in servlet and @ActivationConfigProperty(propertyName = "destinationLookup", propertyValue = "java:global/jms/mySalutationQueue") in MDB. I hope that's fine.

Currently I try to integrate a JavaFX BarChart into my existing Java application. Therefore I need a BufferedImage of my BarChart, so that I can render that snapshot on a Graphics instance.
I adapted the existing BarChartSample.java (Chart Sample | JavaFX Tutorials and Documentation) and removed all animations. The code itselfs works fine but I identified one problem -> my TickLabels are missing
The TickLabels are visible If I use JDK 1.7u51 but if I change to JDK 1.8u05.... than the stlye of my BarChart will be changed and my tick labels are not visible.
Did I missed something or is that a bug?

I have a problem where I have to create random integers from 1 to n + 1. When the array is displayed I have to find the missing integer from the values that are displayed and show that value. I have to use O(n^2) and O(n) operations. I have created this code so far but I cannot figure out how to make my values display n + 1. It is only displaying values 1, 2, 3, 4 and 5 in random order. I also cannot figure out how to find the missing value. I have created a boolean displayed statement but can't determine how to use it in this code.
