Answer:- Major property of a good hash code is that objects which are equal should return the same hash code .
Explanation: Hash codes is a numeric value which is used for identify a object while a equality testing .Hash code can occupy the value of any length and then returns a fixed length value. The value of hash codes are variable.
If two objects are equal then by the method of equal(object) if the hashcode() function is called on both the objects , they produce the same value.
Answer:
The output is "A"
Explanation:
public class Solution {
public static void main(String args[]) {
mystery(7);
}
public static void mystery(int a) { System.out.println("A"); }
public static void mystery(double a) { System.out.println("B"); }
public static void mystery(int a, double b) { System.out.println("C"); }
public static void mystery(double a, int b) { System.out.println("D"); }
}
In the code above; mystery is defined in four different ways called method overloading. Method overloading is when same method is defined with different parameters.
In the first case; mystery will be called if the argument is int.
In the second case; mystery will be called if the argument is double.
In the third case; mystery will be called if the arguments are int and double.
In the fourth case; mystery will be called if the arguments are double and int.
When mystery(7) is called; the mystery method requiring only int will be called and the output is "A".
Technician A is correct.
Electrochemical batteries can be classified into two main categories; Primary Cells and Secondary Cells.
A primary battery or cell cannot easily be recharged after use and is usually recommended to be discarded following discharge. Most primary cells are termed dry due to their capability of utilizing electrolytes contained within absorbent material.
A secondary cell, on the other hand, can be recharged electrically to their original pre-discharge condition.
The retina is the part pf the eye that is similar to the film of a camera. It is a thin layer of cells that is located at the back of the eyeball. This part contains photoreceptor cells which respond to light where the neural signals received undergoes complex processing by other neurons in the retina.
