Part A: Write the QuartsToGallons Java class that declares a named constant to hold the number of quarts in a gallon (4). Also declare a variable to represent the number of quarts needed for a painting job, and assign an appropriate value—for example, 18. Compute and display the number of gallons and quarts needed for the job. Display explanatory text with the values, for example:

Part A: Write the QuartsToGallons Java class that declares a named constant to hold the number of quarts in a gallon (4). Also declare a variable to represent the number of quarts needed for a painting job, and assign an appropriate value—for example, 18. Compute and display the number of gallons and quarts needed for the job. Display explanatory text with the values, for example:

A job that needs 18 quarts requires 4 gallons plus 2 quarts.

The complete code is given in the explanation section

Explanation:

import java.util.Scanner;

public class QuartsToGallons {

   public static void main(String[] args) {

       final int NUMBER_OF_QUARTS = 4;

       int numJobs;

        Scanner in = new Scanner(System.in);

       System.out.println("Enter number of paint in quarts for the painting job?");

       numJobs = in.nextInt();

       int numGallons = numJobs / NUMBER_OF_QUARTS;

       int numQuarts = numJobs % NUMBER_OF_QUARTS;

       System.out.println("The painting Job of " + numJobs + " quarts requires "

               + numGallons + " gallons and " + numQuarts + " quarts of paint.");

   }

}

answer: internal fragmentation is the difference between the (fixed) size of a memory hole and the data within in that memory. for example, if a 1,024 byte block of memory holds 800 bytes of data, then the 224 bytes difference is considered lost to internal fragmentation.

external fragmentation occurs when the sum of memory fragments is large enough to satisfy a request, but the holes are non-contiguous and the request cannot be satisfied. this can occur when memory is dynamically allocated and freed.
