इस लेख में, हम समझेंगे कि जावा में दो नंबरों को कैसे स्वैप किया जाए। यह एक अस्थायी चर का उपयोग करके किया जाता है।
नीचे उसी का एक प्रदर्शन है -
इनपुट
मान लीजिए हमारा इनपुट है -
value_1 : 45 value_2 : 70
आउटपुट
वांछित आउटपुट होगा -
value_1 : 70 value_2 : 45
एल्गोरिदम
Step 1- Start Step 2- Declare three integers: value_1, value_2 and temp Step 3- Read the values Step 4- Assign value_1 to temporary variable Step 5- Assign value_2 to value_1 Step 6- Assign temporary variable to value_2 Step 6- Display the two values Step 7- Stop

import java.util.Scanner; public class NumbersSwap{ public static void main(String[] args){ int value_1, value_2, my_temp; System.out.println("The required packages have been imported"); Scanner my_scan = new Scanner(System.in); System.out.println("A scanner object has been defined "); System.out.println("Enter the first number"); value_1 = my_scan.nextInt(); System.out.println("Enter the second number"); value_2 = my_scan.nextInt(); System.out.println("----Before swap----"); System.out.println("The first value is " + value_1 + " and the second value is " + value_2 ); my_temp = value_1; value_1 = value_2; value_2 = my_temp; System.out.println("----After swap----"); System.out.println("The first value is " + value_1 + " and the second value is " + value_2 ); } }
आउटपुट
The required packages have been imported A scanner object has been defined Enter the first number 112 Enter the second number 34 ----Before swap---- The first value is 112 and the second value is 34 ----After swap---- The first value is 34 and the second value is 112. है
उदाहरण 2
public class NumbersSwap{ public static void main(String[] args){ int value_1 , value_2, my_temp; System.out.println("The required packages have been imported"); value_1 = 45; value_2 = 70; System.out.println("----Before swap----"); System.out.println("The first number is " + value_1 + " and the second number is " + value_2 ); my_temp = value_1; value_1 = value_2; value_2 = my_temp; System.out.println("----After swap----"); System.out.println("The first number is " + value_1 + " and the second number is " + value_2 ); } }
आउटपुट
The required packages have been imported ----Before swap---- The first number is 45 and the second number is 70 ----After swap---- The first number is 70 and the second number is 45
