The union of two tables is basically the total of the two tables, so "or" questions would be my guess.
Answer:
3 years of study - Bachelor's degree
2 years of research - Master's degree
3 years of research to earn a PhD
So, On total it would take 8 years!
Answer:
Super
Explanation:
In object-oriented programming (OOP) language, an object class represents the superclass of every other classes when using a programming language such as Java. The superclass is more or less like a general class in an inheritance hierarchy. Thus, a subclass can inherit the variables or methods of the superclass.
Basically, all instance variables that have been used or declared in any superclass would be present in its subclass object.
Hence, when the keyword super is followed by a parenthesis, it indicates a call to the superclass constructor and it should be the first statement declared in the subclass constructor.
Answer:
Int
byte
Explanation:
In java there are eight primitive data types has a class dedicated, and then we can find eight wrapper classes, I'm going to let you the next table with the 8 example:
Assume the next table byte and Int are primitive data, the different with byte is only the capital letter Byte.
Primitive Wrapper Class
boolean Boolean
byte Byte
char Character
int Integer
float Float
double Double
long Long
short Short
Answer:
Object-Oriented DBMS.
Explanation:
Like classes in Object oriented programming Object-Oriented DBMS is can store objects.It follows an Object oriented data model with the properties of classes and the properties of Object oriented programming also.Objects can be in the form of complex data types or different data types.
