First of all, we will need a function that checks if a number is prime or not:

boolean isPrime(int n){

 for(int i=2; i<=math.sqrt(n); i++){

   if(n % i == 0) return false;

 }

 return true;

}

Then, in the main program, we will call this function with all the desired inputs, and we will print the prime numbers:

for(int n=100; n<= 1000; n++){

 if(isPrime(n)) print(n);

}

Write a class Bug that models a bug moving along a horizontal line. The bug moves either to the right or left. Initially, the bu
Harrizon [31]

Answer:

Explanation:

The following code is written in Java. It creates the Bug class with the position and direction variables. Then it creates a constructor, move method, turn method, and getPosition method. Finally, a bug object called bugsy is created in the main method, and we move it once to the right, then again to the right, and then we turn it and move it 5 times to the left, printing out the position when it is done moving. Output can be seen in the attached picture below.

class Brainly {

   public static void main(String[] args) {

       Bug bugsy = new Bug(10);

       bugsy.move();

       System.out.println("Current bug position: " + bugsy.getPosition());

       bugsy.move();

       System.out.println("Current bug position: " + bugsy.getPosition());

       bugsy.turn();

       bugsy.move();

       bugsy.move();

       bugsy.move();

       bugsy.move();

       bugsy.move();

       System.out.println("Current bug position: " + bugsy.getPosition());

   }

}

class Bug {

   char direction = 'r';

   int position = 0;

   public Bug(int initialPosition) {

       this.position = initialPosition;

   }

   public void turn() {

       if (this.direction == 'r') {

           this.direction = 'l';

       } else {

           this.direction = 'r';

       }

   }

   public void move() {

       if (this.direction == 'r') {

           this.position += 1;

       } else {

           this.position -= 1;

       }

   }

   public int getPosition() {

       return this.position;

   }

}
