rjkz [21]

Answer:

Explanation:

The following code is written in Java. It is a method that calculates the square root of a number as requested. The method first checks with an IF statement if the parameter value is a positive number and then calculates the square root and prints it to the screen. Otherwise, it prints Number must not be negative. A test case has been provided in the main method and the output can be seen in the attached image below.

import java.util.Scanner;

class Brainly {

   public static void main(String[] args) {

       Scanner in = new Scanner(System.in);

       System.out.print("Enter a number of type double to calculate square root:");

       double num = in.nextDouble();

       rootPositive(num);

   }

   public static void rootPositive(double num) {

       if (num > 0) {

           System.out.println(Math.sqrt(num));

       } else {

           System.out.println("Number must not be negative.");

       }

   }

}

Evaluating sorts given the following array: 41, 32, 5, 8, 7, 50, 11 show what the array looks like after the first swap of a bub
irga5000 [103]

The way that  the array will looks like after the first swap of a bubble sort in ascending order is   {5,32,41, 8,7,50,11}.

<h3>Who do you Write sort code in JAVA?</h3>

It will be:

class SSort

{

  void sort(int array[])

  {

      int n = array.length;

      for (int i = 0; i < 2; i++)

      {

          int minimum_index = i;

          for (int j = i+1; j < n; j++)

              if (array[j] < array[minimum_index])

                  minimum_index = j;

           int temp = array[minimum_index];

          array[minimum_index] = array[i];

          array[i] = temp;

      }

  }

   void printArray(int array[])

  {

      int n = array.length;

      for (int i=0; i<n; ++i)

          System.out.print(array[i]+" ");

      System.out.println();

  }

  public static void main(String args[])

  {

      SSort s = new SSort();

      int array[] = {41, 32, 5, 8, 7, 50, 11};

      s.sort(array);

      System.out.println("After first two iteration of Selection sort:");

      s.printArray(array);

  }

}

Therefore, The way that  the array will looks like after the first swap of a bubble sort in ascending order is   {5,32,41, 8,7,50,11}.
