TOSHKENT AXBOROT TEXNALOGIYALARI UNIVERSITETI FARG’ONA FILIALI TT VA KT FAKULTETI 652-20 GURUH TALABASI XUDOYBERDIYEV XASANJONNING JAVA DASTURLASH FANIDAN KALKULATOR DEDLAYN ISHI

Topshiriq:
Java dasturlash tili orqali konverter va kalkulator dasturini ishlab chiqish.

Dasturning kod qismi:

1. import java.util.Scanner;

2.
3. public class Calculator {
4. public static void main(String[] args) {
5. Scanner input = new Scanner(System.in);
6.
7. System.out.println("Kalkulyator dasturiga hush kelibsiz!");
8. System.out.println("Iltimos, birinchi sonni kiriting: ");
9. double num1 = input.nextDouble();
10.
11. System.out.println("Iltimos, ikkinchi sonni kiriting: ");
12. double num2 = input.nextDouble();
13.
14. System.out.println("Iltimos, amalni tanlang (+, -, *, /): ");
15. char operator = input.next().charAt(0);
16.
17. double result;
18.
19. switch(operator) {
20. case '+':
21. result = num1 + num2;
22. break;
23.
24. case '-':
25. result = num1 - num2;
26. break;
27.
28. case '*':
29. result = num1 * num2;
30. break;
31.
32. case '/':
33. result = num1 / num2;
34. break;
35.
36. default:
37. System.out.println("Noto'g'ri amal tanlandi!");
38. return;
39. }
40.
41. System.out.println(num1 + " " + operator + " " + num2 + " = " + result);
42. }
43. }
44.
Dastur natijasi:
1. java -cp /tmp/TW1sP6fA8h Calculator
2. Kalkulyator dasturiga hush kelibsiz!
3. Iltimos, birinchi sonni kiriting:
4. 22
5. Iltimos, ikkinchi sonni kiriting: 33
6. Iltimos, amalni tanlang (+, -, *, /):
7. +
8. 22.0 + 33.0 = 55.0
9.
Ushbu dasturda qo’shish, ayrish, bo’lish va ko’paytirish amallarini bajarish mumkin.

2. Java dasturlash tilida Asal maaxsulotining Kg va Litr o’lchov birliklarini konvertor dasturini yaratish.
Dastur kod qismi:
1. import java.util.Scanner;
2.
3. public class Main {
4. public static void main(String[] args) {
5. Scanner scanner = new Scanner(System.in);
6.
7. System.out.print("Iltimos, o'lchov birlikni tanlang (kg yoki L): ");
8. String birlik = scanner.nextLine();
9.
10. if (birlik.equals("kg")) {
11. System.out.print("Asal miqdorini kg da kiriting: ");
12. double asalKg = scanner.nextDouble();
13. double asalL = asalKg / 1.38;
14. System.out.println("Asal miqdori " + asalL + " L ga teng.");
15. } else if (birlik.equals("L")) {
16. System.out.print("Asal miqdorini L da kiriting: ");
17. double asalL = scanner.nextDouble();
18. double asalKg = asalL * 1.38;
19. System.out.println("Asal miqdori " + asalKg + " kg ga teng.");
20. } else {
21. System.out.println("Noto'g'ri birlik kiritildi!");
22. }
23. }
24. }
25.

Natija:
1. java -cp /tmp/TW1sP6fA8h Main
2. Iltimos, o'lchov birlikni tanlang (kg yoki L): kg
3. Asal miqdorini kg da kiriting: 2
4. Asal miqdori 1.4492753623188408 L ga teng.
5.
Ushbu dasturda Asalning kilogramini litrga nisbati yoki aksincha holatini aniqlash mumkin.

Malumot uchun: 1 Litr asal 1.38 kilogramga teng.
