Java Java.lang.ExceptionInInitializerError Error Solution __java

The cause of the Java.lang.ExceptionInInitializerError error is that an error occurred while initializing the class. That is, when the class is loaded, there is an error executing the static property, method block.

Like what

public class AA {

private static AA = new AA ();

Private AA () {//Construction method

Init ();

}

public void init () {

....  }

}

When the class is initialized, the Init method is invoked and the Java.lang.ExceptionInInitializerError error is reported if the Init method fails with such initialization failure

Similarly, in implementing

static{

...

}

Method block, you may also report this error.
