Question

Write a java program that reads in the rated bursting pressure and the current pressure, and determines if the boiler is operating at a safe pressure. For example:

Enter the rated bursting pressure of the boiler (psi): 625

Enter the current pressure (psi): 137.8

The maximum safe pressure is 208.3 psi.

The current pressure is safe.

or

Enter the rated bursting pressure of the boiler (psi): 625

Enter the current pressure (psi): 250

The maximum safe pressure is 208.3 psi.

WARNING! The current pressure is not safe.

Hint: Use three variables: burst_psi current_psi, and max_safe_psi

Answer 1

/* Designing the program exactly as per the comments mentioned*/

import java.util.*;
import java.lang.*;
import java.io.*;
public class Main
{
   public static void main(String[] args)
{
   Scanner s=new Scanner(System.in);
   double burst_psi,current_psi,max_safe_psi=208.3;
   System.out.print("Enter the rated bursting pressure of the boiler (psi):");
   burst_psi=s.nextDouble();
   System.out.print("Enter the current pressure (psi):");
   current_psi=s.nextDouble();
   System.out.println("The maximum safe pressure is 208.3 psi.");
   if(current_psi>max_safe_psi)
       System.out.println("WARNING! The current pressure is not safe.");
   else
       System.out.println("The current pressure is safe.");
}
}

Sample output:

Enter the rated bursting pressure of the boiler (psi):625
Enter the current pressure (psi):250
The maximum safe pressure is 208.3 psi.
WARNING! The current pressure is not safe.

Refer the below screen short for more details:

public static void main(String[] args), Scanner s=new Scanner(System.in); double burst_psi, current psi,max_safe psi=208.3; System.out.print("Enter the rated bursting pressure of the boiler (psi):") burst_psi=s.nextDouble(); System.out.print("Enter the current pressure (psi):"); current_psi=s.nextDouble(); System.out.println("The maximum safe pressure is 208.3.psi."): if(current_psi>max_safe_psi) System.out.println("WARNING! The current pressure is not safe."), else System.out.println("The current pressure is safe.");
