This is false. Not all java classes need a main method. You can create you own class below the class with the main method and put your own user-created methods into it. Classes without a main method can be in its own separate class even.

Write a method that takes a RegularPolygon as a parameter, sets its number of sides to a random integer between 10 and 20 inclus
Sergio [31]

Answer:

import java.lang.Object

import java.lang.Math

public class RegularPolygon  extends java.lang.Object{

  public void randomize(RegularPolygon c){

       int min = 10, max1 = 20;

       double  min1 = 5, max1 = 12;

       double range = (max - min) + 1;

       double range1 = (max1 -min1) + 1

       int side = (Math.random() * range) + min;

       double len = (Math.random() * range1) + min1;

       c.setNumSides(side);

       c.setSideLength( len);

 }

 public static void main(String[] args) {

    RegularPolygon r = new RegularPloygon();

    randomize(r);

 }

}

Explanation:

The randomize method accepts a regular polygon class as its only parameter and assigns a random number of sides and the length of these sides with the 'Math.random' function.

g100num [7]

Answer:

Incomplete Question.

I'll answer this question based on general terms

Explanation:

Two Factor Authentication, abbreviated as 2FA.

It is a type of authentication that requires the presentation of two credentials for access to personal data and information.

The credentials needed for a 2FA are

1. Either of the following; PIN, Password or Pattern

2. Your device or gadget which could be an ATM Card, Mobile Phone

3. Biometrics such as fingerprint, voice input

Number one is often referred to as "Something you know"

Number two is referred to as "Something you have"

Number three is referred to as "Something you are"

The 2FA doesn't require the three aforementioned credentials. It only needs just two of the credentials to provide its authentication.

Draw a timeline for each of the following scheduling algorithms. (It may be helpful to first compute a start and finish time for
12345 [234]

Answer:

See explanation below

Explanation:

Previos concepts

First Come First Serve (FCFS) "is an operating system scheduling algorithm that automatically executes queued requests and processes in order of their arrival".

Shortest job next (SJN), or the shortest job first (SJF) or shortest "is a scheduling policy that selects for execution the waiting process with the smallest execution time".

Shortest remaining time (SRF) "is a scheduling method that is a preemptive version of shortest job next scheduling'".

Round robin (RR) is an algorithm where the time parts "are assigned to each process in equal portions and in circular order, handling all processes without priority"

Solution for the problem

Assuming the dataset given on the plot attached.

Part a

For this algorithm the result would be:

Job A   0-6

Job B   6-(6+3) = 6-9

Job C   9-(9+1) = 9-10

Job D   10-(10+4) = 10-14

Part b

For this algorithm the result would be:

Job A   0-6

Job C   6-(6+1) = 6-7

Job B   7-(7+3) = 7-10

Job D   10-(10+4) = 10-14

Part c

For this algorithm the result would be:

Job A   0-1  until 14

Job B   2-(2+3) = 2-5

Job C   3-(3+2) = 3-5

Job D   9-(9+5) = 9-14

Part d

For this algorithm the result would be:

Job A   0-2 , 7-9, 12-14

Job B   2-4, 9-10

Job C   4-(4+1) = 4-5

Job D   5-7, 10-12
