Consider the following code where you declare a variable of primitive type int: int x; x = 10; In this example the variable x is an int and Java will initialize it to 0 for you. When you assign it to 10 in the second line your value 10 is written into the memory location pointed to by x. But, when you try to declare a reference type something different happens. Take the following code: Integer num; num = new Integer(10); The first line declares a variable named num, but, it does not contain a primitive value. Instead it contains a pointer (because the type is Integer which is a reference type). Since you did
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 exception http://craftingjava.blogspot.com/2012/06/javalangexceptionininitializererror.html you may be able to guess that this exception is related to initialization of a https://examples.javacodegeeks.com/java-basics/exceptions/java-lang-exceptionininitializererror-how-to-handle-exception-initializer-error/ 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 the keyword static error java 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 error message the original java lang nullpointerexception 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.
