Write a class named GasTank containing: An instance variable named amount of type double, initialized to 0. An instance variable

named capacity of type double. A constructor that accepts a parameter of type double. The value of the parameter is used to initialize the value of capacity. A method named addGas that accepts a parameter of type double. The value of the amount instance variable is increased by the value of the parameter. However, if the value of amount is increased beyond the value of capacity, amount is set to capacity. A method named useGas that accepts a parameter of type double. The value of the amount instance variable is decreased by the value of the parameter. However, if the value of amount is decreased below 0, amount is set to 0. A method named isEmpty that accepts no parameters. isEmpty returns a boolean value: true if the value of amount is less than 0.1, and false otherwise. A method named isFull that accepts no parameters. isFull returns a boolean value: true if the value of amount is greater than capacity-0.1, and false otherwise. A method named getGasLevel that accepts no parameters. getGasLevel returns the value of the amount instance variable. A method named fillUp that accepts no parameters. fillUp increases amount to capacity and returns the difference between the value of capacity and the original value of amount (that is, the amount of gas that is needed to fill the tank to capacity).

Answer:

The class GasTank is defined below

All the steps are briefed in comments

public class GasTank {

// instance variable initialization

private double amount = 0;

//declaring instance variable capacitance

private double capacity;

//constructor having parameter of type double

public GasTank(double i)

{

capacity = i;

}

// addGas method for increasing gas quantity.

public void addGas(double i)

//quantity of gas increased is added to the existing amount. If it becomes more than total capacity, amount is set to capacity

{ amount += i; if(amount > capacity) amount = capacity; / amount = amount < capacity ? amount+i : capacity;/ }

//useGas method having parameter of type double

public void useGas(double i)

//the parameter given is deducted from 0 and if results less than 0, remains equal to 0

{ amount = amount < 0 ? 0 : amount - i; }

//method isEmpty

public boolean isEmpty()

//Returns true if volume is less than 0.1 else false

{ return amount < 0.1 ? true : false; }

//method isFull

public boolean isFull()

//returns true if the value of amount is greater than  0.1 else false.

{ return amount > (capacity-0.1) ? true : false; }

//method getGasLeve

public double getGasLevel()

//Returns the value of amount instance variable

{ return amount; }

//method fillUp

public double fillUp()

//returns the difference between the capacity and the amount

{ double blah = capacity - amount; amount = capacity; return blah; }

}

What is the difference between ‘’ and “” string type in python?
Mekhanik [1.2K]

Answer:

There is no difference between ‘’ and “” string type in python. Both are used to hold the string or sequence of character in the python. triple """ """ can also use for the same.

Example:

str1 = "aeiou"

str2 = 'aeiou'

str3 =""" hello"""

print(type(str1), type(str2),type(str3))

<class 'str'> <class 'str'> <class 'str'>

Here all are used to hold string or sequence of character.

Instructions Write a program that allows the user to enter the last names of five candidates in a local election and the number
KengaRu [80]

Here is code in java.

import java.util.*;

class Election

{ //main method

   public static void main(String args[]){

      // create an object of Scanner class to read input

      Scanner s = new Scanner(System.in);

      // string array to store name of candidates

       String name[] = new String[5];

       // int array to store vote count of candidates

       int v_count[] = new int[5];

       double p = 0;

       int i = 0, sum = 0, high =0, win = 0;

for(i = 0; i < 5;i++)

       {

          System.out.print("last name of Candidate " + (i+1) + ":");

          // read name of Candidate

          name[i] = s.next();

          System.out.print(" number of votes received: ");

          // read vote of Candidate

           v_count[i] =s.nextInt();

if(v_count[i] > high)

              {

                  // highest vote

                  high = v_count[i];

                  win = i;

              }

              // total vote count

           sum +=v_count[i];

       }

     // printing the output

      System.out.println("\nCandidate\tVotes Received\t% of TotalVotes\n");

       for(i = 0; i < 5;i++)

       {

           // % of vote of each Candidate

           p =(v_count[i]*100)/sum;

           // print the output

          System.out.println(name[i] + "\t\t" + v_count[i] + "\t\t\t" +p);

       }

       // print the total votes

      System.out.println("\nTotal Votes:\t" + sum);

      // print the Winner of the Election

       System.out.println("Winner of the Election is: " + name[win]);

   }

}

Explanation:

Create a string array "name" to store the name of candidates.Create Integer array "v_count" to store votes os each candidates.Calculate total votes of all candidates and find the highest vote amongst all candidate and print it.Find % of votes received by each candidate.Print these stats.

Output:

last name of Candidate 1:patel

number of votes received: 54

last name of Candidate 2:singh

number of votes received: 76

last name of Candidate 3:roy

number of votes received: 33

last name of Candidate 4:yadav

number of votes received: 98

last name of Candidate 5:sharma

number of votes received: 50

Candidate       Votes Received  % of TotalVotes

patel           54                      17.0

singh           76                      24.0

roy             33                      10.0

yadav           98                      31.0

sharma          50                      16.0

Total Votes:  311

Winner of the Election is: yadav
