Answer:
The correct answer for the given question is "The program has a runtime NullPointerException because test is null while executing test.x"
Explanation:
In this code their is run time exception will occur in Main method i.e "java.lang.NullPointerException "because the object of the Test class i.e test will initialized by "null" .So on executing the statement test.x it gives an Runtime Exception.The "NullPointerException" can occur if we assign the object to the "null" value that why it produce an java.lang.NullPointerException
It can handle 8 threads at once.
Answer:
(ACD'+BE)
Explanation:
(A+B)(C+B)(D'+B)(ACD'+E)
Product of (A+B)(C+B)
(A+B)(C+B)=AC+AB+BC+B^2 = AC+B(A+C+B)=AC+B
Product of (D'+B)(ACD'+E) with AC+B
(AC+B)(D'+B)(ACD'+E)
(AC+B)(D'+B)=ACD' + ACB +BD +B = ACD'+B(AC+D+1)=ACD'+B
Then we get:
(ACD'+B)(ACD'+E) = ACD'+ACD'E+ACD'B+BE
ACD'(1+E+B)+BE =ACD'+BE
