In your opinion which of the following is the most convenient way to create a bootable USB flash drive? Why?
77julia77 [94]

Answer:

here

Explanation:

Plug the USB drive into your computer’s USB port.

Search for the “cmd” application in the Windows start menu, right-click on the item, and select “Run as administrator” from the context menu. This opens a small window with white text on a black background.

Type the command “diskpart” and confirm your input with the enter key (you’ll also do this after every other entered command). This starts the storage device manager.

Enter the command “list disk” to display all available storage devices.

You can recognize your USB by its storage capacity, and it’s usually listed as “disk 1”. In the system partition, “disk 0” is usually your PC, so a hard drive or solid state drive in your computer.

Based on the assumption that your USB has the label “disk 1”, enter the command “sel disk 1” to select it (or the corresponding “disk 2”, etc.).

Enter then command “clean” to delete all files from the USB.

Enter the command “create partition primary” to create a main partition.

Enter the command “list par” and select the newly created main partition with “sel par 1”.

Activate the partition with the command “active”.

Format the USB with the command “format fs=FAT32 label=“WINDOWSUSB” quick override” (in place of “WINDOWS USB” you can also choose another label, so long as it doesn’t contain any spaces or special characters. The drive will later be displayed under this name if you plug into a running Windows computer). Formatting may take a while. You can track its progress in the percentage bar.

As soon as the process is finished, enter the command “assign” to automatically assign a drive letter (for example “G:”) to your USB.

Enter “exit” to close DiskPart, and then “exit” again to close the command prompt

import javax.swing.JOptionPane;

public class BadDate {

  private static final int MINIMUM_YEAR = 0, MINIMUM_MONTH = 1, MAXIMUM_MONTH = 12, MINIMUM_DAY = 1, MAXIMUM_DAY = 31;

  private int year = 0;

  private int month = 0;

  private int day = 0;

  public void housekeeping() {

      String yearData = JOptionPane.showInputDialog("Enter year");

      String monthData = JOptionPane.showInputDialog("Enter month");

      String dayData = JOptionPane.showInputDialog("Enter day");

      this.year = Integer.parseInt(yearData);

      this.month = Integer.parseInt(monthData);

      this.day = Integer.parseInt(dayData);

  }

 

  public boolean isLeapYear(){

      if(((this.year % 400) == 0) || (((this.year % 4) == 0) && ((this.year % 100) != 0)))

          return true;

      else

          return false;

  }

  public void endOfJob() {

      boolean validDate = true;

     

      if((month < MINIMUM_MONTH) || (MAXIMUM_MONTH < month))

          validDate = false;

      else {

          if(((month == 1) || (month == 3) || (month == 5) || (month == 7) ||

                  (month == 8) || (month == 10) || (month == 12)) && ((day < 1) || (31 < day)))

              validDate = false;

         

          else if(((month == 4) || (month == 6) || (month == 9) || (month == 11)) && ((day < MINIMUM_DAY) || (30 < day)))

              validDate = false;

         

          else if(month == 2) {

              if(isLeapYear() && ((day < MINIMUM_DAY) || (29 < day)))

                  validDate = false;

              else if((day < MINIMUM_DAY) || (28 < day))

                  validDate = false;

          }

      }

     

      if (validDate) {

          JOptionPane.showMessageDialog(null, "Date: " + this.month + "/" + this.day + "/" + this.year);

          System.out.println(this.month + "/" + this.day + "/" + this.year + " is a valid date");

      } else {

          JOptionPane.showMessageDialog(null, this.month + "/" + this.day + "/" + this.year + " is an invalid date");

          System.out.println(this.month + "/" + this.day + "/" + this.year + " is an invalid date");

      }

  }

  public static void main(String args[]) {

     

      BadDate date = new BadDate();

      date.housekeeping();

      date.endOfJob();

  }

}

Explanation:

  • Take the year, month and day from user  as an input.
  • Check if the year of this date is a leap year inside the isLeapYear method.
  • Inside the housekeeping method , take the year, the month and day  to ensure that date is valid .
  • Display positive response by printing valid date if date is correct.
  • Otherwise alert user that an invalid date was entered.
