I am writing a program in java. The screenshot of the program is as follows:
The method append (string) is undefined for the JTextFeild
As you can see above I get a red line under "append". Why is that so? I have observed that I always get it, when I use a jtext field. When I use the jtext area instead of the field, it is resolved.
Why is this so? Can anyone please guide me how to get rid of this error?
Waiting for your replies.
I am basically a java programmer and I have been working on a code to convert kilograms to pounds for the last few days. I have written the following code successfully:
There is something wrong in my code, which I am not able to detect. My program was in the jdk bin and I have a path set to a folder in my documents.
Please help me and guide me as to where I am making a mistake.
Waiting for your suggestions.
I am using netbeans to refer to integrated development environment (IDE) for developing with java. I have installed the version 7 of IDE but before that I was using the 6.9 version which was running perfectly fine. The version 7 of IDE results in more frequent errors than version 6.9. I don’t know why but I keep on getting the following error message on my screen:
Fatal Error: Cannot recover after last error. Any further errors will be ignored.
From line 12, column 18; to line 21, column 12
In the previous day I had done updating (all thing but the kernel) of my fedora 9. Right now I got to see that the updating some java type broke down. I started ny notes and tried to connect to the domino server(pop up when new mail comes) after that got crashed.
In dmesg I got: notes2w: segfault at 0 ip 001a4fe5 sp bfa3ea60 error 6 in libj9prt23.so[195000+21000]
How could it be possible to debug this? Could someone from the enterprise of java help me out to solve it? I usually update once or twice in a week.
I am trying to make a photo booth app but I can't seem to figure it out. I am trying to allow the app to have access to webcams in the local vicinity, gain the frame and then show it to the user after a special effect has been added to it.
I used Jpanel & swing components to make the app; however, my client is asking the app to be run in the browser. There is an access error when I use the applet to access the webcam. I am aware I need to sign the applet, even after doing this it won't work.
I have Java installed on my laptop. A message popped-up saying that the latest Java version was available for download but when I try to install it the program suddenly shuts down. How do I install the latest Java version?
This morning, I am getting this error message when I’m trying to install a program (I attached the image below). What exactly is this JRE missing mean? Can any experts provide an answer for me. I’m curious to know more about it.
Any help would be appreciated. Thank you.

Whew, I am already sick and tired of the errors I have met in updating. It would just hang when it reaches 3% of the update. An error message would then appear: “ERROR: Java Error - Context: HD Tele ConfiguratorName = 1 Parameters: java.lang.NullPointerException”. I can’t figure out why this has come up. I also have tried doing it again but the error would just not disappear. Can you please help me with this? I mean, I am really counting to those who would share their expertise about this problem. Are there other ways to have it updated and avoiding this tiring error? I totally have no idea how to fix this and you might just be the person who can help me with this. Thanks a lot.
I've been having this problem a couple of times now. The .exe I'm trying to open up is a Shimeji and it had worked perfectly fine in a previous version of Java. But now, every time I try to open it, another window flashes up and I assume that it's trying to get me to update to a new version of Java since it opens up my browser with a Japanese version of the website whenever I click the "yes" button. My question is if the .exe had worked perfectly fine in the previous Java, why must I update to a new one and not get the .exe to work anymore if I don't? I'm worried that it might damage something and I won't get to open the Shimeji anymore.
