I did some things with bindings and now java.lang.exceptionininitializererror eclipse whenever I start my program, before it even intializes the form, it gives me an error The exception in thread main is ocuring before the form is even an intialized object yet. The form is not even an object yet. Every line in my main() causes an exception. Random stuff. I don't understand it at all. Here is the error.

to the java.lang. package.This exception extends the Linkage Error.On seeing this exception you might have no idea about the exception as i have confused. What is Exception In Initialize Error? On seeing the name of the http://craftingjava.blogspot.com/2012/06/javalangexceptionininitializererror.html exception you may be able to guess that this exception is related to initialization http://javarevisited.blogspot.com/2014/06/exception-in-thread-main-java-lang-exceptionininitializerError-fix.html of a variable.Yes of course this error is related to the initialization of a static variables.The variable may be of primitive type or user defined type.You might all have known about the static initializer of a class. A static initializer is a block enclosed within curly braces without having any name and return type except having initializer error the keyword static as follows static { //initialization of values; } The static initializer block is meant for initializing the static variables. Why this ExceptionInInitializer Error is thrown? If any error occurs during the initialization of variables inside the static initializer block of a class then this error would be thrown.Thus we have to understand that this exception is thrown ,when other exceptions arise in the static initializer block.In the exception in initializer error message the original cause for this exception is also shown. How to fix this exception? Since this exception arises in consequence of some other exceptions that arises in the static initializer block. We have to ensure that the original cause of this exception is fixed otherwise we cannot be able to deal with this exception in any way. Example situations of this exception: import java.io.*; import java.lang.*; class Exin { private static String name; private static char c; public Exin(String n) { name=n; } static { c=name.charAt(12); } } public class Exin1 { public static void main(String args[]) { Exin e=new Exin("ganesh"); } } Exception thrown: Exception in thread "main" java.lang.ExceptionInInitializerError at Exin1.main(Exin1.java:22) Caused by: java.lang.NullPointerException at Exin.(Exin1.java:14) ... 1 more Note that in the above program i have tried to access the 12th character in the string "ganesh" using the method charAt() which causes null pointer exception thereby causing the ExceptionInInitializer error.

java.lang.ExceptionInInitializerError in Java Program JVM throws java.lang.ExceptionInInitializerError, when there is an Exception inside static initializer block. If you know about static variable in Java, then you may know that they are initialized at the time of class loading. If there is an Exception during that initialization of static variables, you will see ExceptionInInitializerError in Java. This could be any exception e.g. java.lang.ArrayIndexOutOfBound or java.lang.NullPointerException. Java developers often confused with this error because, they think that they have not defined any static initializer block, then how come they are getting ExceptionInInitializerError;well, by default Java combines all static variable initialization inside a static initializer block and initialize them in the order they are declared in source file. If suppose a variable ABC is declared at line 1, used at line 2 but initialized at line 3, then code at line 2 will throw java.lang.NullPointerException, which will be wrapped by JVM in ExceptionInInitializerError, and if that code happens to be executed by main thread then you will see "Exception in thread "main" java.lang.ExceptionInInitializerError" in your console or log file. In a large application with huge log files sometime this error got unnoticed, and programmers get alerted by dreaded java.lang.NoClassDefFoundError. Unfortunately this error comeswhen client class tries to use the class, which was not loaded because of ExceptionInInitializerError. Since class loading was failed earlier, JVM is now throwing NoClassDefFoundError. Sometimes this misleads Java developer, and they start looking at classpath, path and java.library.path for missing class, and confused them with hell not finding any anomalies. If you are investigating cause ofNoClassDefFoundError,it's always a better idea to check your application log files for ExceptionInInitializerError before looking at CLASSPATH. In this article, we will see an example code, which generates exception during static initialization and results in "Exception in thread "main" java.lang.ExceptionInInitializerError". In later part, we will see how to fix this error. Cause of "Exception in thread "main" java.lang.ExceptionInInitializerError" As with any other error or exception, by first looking at this line, you know that exception is java.lang.ExceptionInIniti
