About Question enthuware.ocajp.i.v8.2.1031 :

[atrofimov]

Hi there,
I wonder why this will not compile:
public class X {
static {
throw new NullPointerException();
}
}

[admin]

It should compile. The answer should be changed to ExceptionInInitializerError.
Fixed.
thank you for your feedback!

Hi, probably this question is ambiguous - in fact the Oracle compiler 1.8.0_121 for Linux refuses to compile the code because of the line "throw new NullPointerException();":

X.java:2: error: initializer must be able to complete normally
static {
^
1 error

This ambiguity probably could be removed if the code were changed for example as follows:

Code: Select all

public class X {
static {
problem();
}
static void problem() { throw new NullPointerException(); }
}

or

Code: Select all

public class X {
static String str;
static {
int len = str.length();
}
}

The quoted code snippets are compiled by aforementioned compiler without any errors, and they cause the expected ExceptionInInitializerError at run time.

[admin]

You are right. I was mistaken. I am not sure why I thought it should compile. It doesn't compile on Windows compiler either. The original answer was correct. I have changed it back.

X.java:2: initializer must be able to complete normally
static{
^
1 error


thank you for your feedback!
