Answer:
2. <em>A reference of type A can be treated as a reference of type B</em> - False
Base class or its objects are not related to their derived class (or its objects).
Explanation:
class A {
int a;
public A() {
a = 7;
}
}
class B extends A {
int b;
public B() {
b = 8;
}
}
///////////////////////////////////////////////////////////////////////////////////////////////////////
1. <em>After the constructor for class B executes, the variable a will have the value 7 </em>- True.
When an object of a derived class is declared, the constructor of base class is called before the constructor of derived class (is called).
3. <em>Both variables a and b are instance variables </em>- True.
Classes can have instance, or member, variables and methods.
4.<em> After the constructor for class B executes, the variable b will have the value 8</em> - True.
When object of class B is declared, its constructor was called, which initialized variable b to 8.
Answer:
zero ( 0) times.
Explanation:
In the code;
i = 2
while ( i > 2){
i = floor( i/2 );
z = z + 1;
}
the variable " i " is assigned the integer " 2 ", then the while statement loops with a condition of a greater " i " value and divides the value by two for every loop.
But in this case, the while statement is not executed as the value of " i " which is 2 is not greater than but equal to two.
Answer:
A. dict = {‘Name’: ‘Matthew’, ‘Age’: 14, ‘School’: ‘ABC School’}
Explanation:
Since <em>python does not use type when declaring a variable</em>, you must make sure you make your variables correctly or else it won't compile correctly. Lists use braces[]; Strings use quotes, "" or ''; Integers are just declared with a number(s); Dictionaries use brackets{} and inside are <u>attributes of something</u>. For instance, you can use dictionaries to describe ages, {'"Bryan": 6, "Alex": 13, etc.} <u>Sort of like a json file</u>. Dictionaries also tend to use <u>uppercase letters</u> when describing something. The only answer that has all the attributes correct is A. dict = {‘Name’: ‘Matthew’, ‘Age’: 14, ‘School’: ‘ABC School’}
hope i helped :D
=(Happy)&(Birthday) this is how it would be formatted
