try-multicatch with ExceptionInInitializerError and ArithmeticException confusion

Question

public class HelloWorld {
   static {
    try {
        int i=10/0;
     } catch(ExceptionInInitializerError | ArithmeticException e ) {
            e.printStackTrace();
     }
   } 

   public static void main(String []args) {
        System.out.println("Hello World");
     }
}

Output:

java.lang.ArithmeticException: / by zero

There is no actual purpose to this code. But just wondered why it threw ArithmeticException over ExceptionInInitializerError. Just trying out multi-catch statement and ran into this.

The code below throws ExceptionInInitializerError. So logically, if I use try-multicatch, it should catch ExceptionInInitializerError, but its not the case here. Can anyone help me out here.

public class HelloWorld {

     static int i = 10/0;

     public static void main(String []args){
        System.out.println("Hello World");
     }
}

Output:

Exception in thread "main" java.lang.ExceptionInInitializerError                                                                                                   
Caused by: java.lang.ArithmeticException: / by zero

Answer 1

static
{
    try
    {
        int i = 10 / 0;
    }
    catch (ExceptionInInitializerError | ArithmeticException e)
    {
        e.printStackTrace();
    }
}

This causes an ArithmeticException but since you catch it, there is not problem with the Initialization.

static
{
    int i = 10 / 0;
}

This causes an ArithmeticException but since you do not catch it, the ArithmeticException causes an ExceptionInInitializerError. You can see it from the stack shown below.

Exception in thread "main" java.lang.ExceptionInInitializerError
