                                                fahrenheit = (9 / 5) * celsius + 32

[2] Answer :

-------------------------------------------------------------------------------------------------------------------------
import java.util.Scanner;
public class Lab2_2 {
   
  public static void main(String[] args) {
  
                  // Step 1 : Prompt the input
                 Scanner input = new Scanner(System.in);
   
                  // Step 2 : Enter a degree in Celsius
                 System.out.print("Enter a degree in Celsius: ");
                 double celsius = input.nextDouble();
   
                 // Step 3 : Calculation
                 double fahranheit = ((9.0/5)* celsius) + 32;
   
                 // Step 4 : Display Celsius in Fahrenheit
                 System.out.println( (int) celsius + " Celsius is " + fahranheit + " Fahranheit" );
  }
}
