Answer:
A generalized class used only to create related derived classes
Explanation:
An abstract class is a class which cannot be instantiated on its own. It is defined using an abstract keyword. However, an abstract class can be inherited from and the derived class can actually be instantiated. For example:
abstract class A{
}
class B extends A{
void test(){
}
}
Here class A is an abstract class, while class B inherits from A. Now we can create an instance of class B as follows:
B b = new B();
b.test();
Explanation:
Material systems developer typically combines the skills of a programmer with the multitasking expectations of developing 3 dimensional models of objects, enhancing the graphical effects.
The programmer simply does not have to translate the image but he needs to map the objects in some different ways that give it a 3D look. The object is composed of from material instead of simple modeling
Answer:
b. Associativity
Explanation:
Associativity specifies the order in which operators are processed vis a vis operands/values in an expression. For example: Consider the expression: a + b + c. Here a + b is evaluated first before adding the result with c as the '+' operator is left associative. The default associativity can also be overridden by the use of parentheses. For example a + (b + c) . In this case b+c will be evaluated first.
