aha, the way I see it is this
a=b -> the value of this expresion is b
b[3] -> the value of this is 0
a[0] -> the velue of this is 11
Can you clearify this step:
(a = b)[3] ==> a[3]=b[3]
The one I pasted above.

Aha so the rule if you make a compiler cast it to lower type you get compilation error.

Aha so the rule is that in case you need to cast to lower type you get compilation error?

yes but here is 1st the conversation from long to int. Inside the arithmetic expresion?

I have problem understanding this piece of code in Java


In my opinion the code above shoulnd't compile but it does.
It shouldn't compile because in line 2 there is an implicit conversation from long to int which shouldn't be allowed by compiler ??

If I decided for OCA 808 certification for Java 8 would I need to attend some (online) classes or do you just need to pay for exam?
What if you don't pass the exam?
I would like to get Java certification but I don't know which certificate is best to complete? Do you have any suggestions? Are there different companies offering these certificates?
I think I would like to have JAVA SE certification or maybe JAVA EE.
Where should I start, should I attend some online classes and what literature(for practice) I need?


I created this progam in MIPS and I don't know why I get the error below?
