Can you swap 2 strings in Java?

Can you swap 2 strings in Java?

Swapping two strings usually take a temporary third variable. One of the approach to accomplish this is to concatenate given two strings into first string. Extract string 2 using substring (0, length(string1) – (string2)) i.e. in our case it will be substring(0, (11-4)).

How do you reverse a string without third variable?

Algorithm to Reverse String Without Temporary Variable

  1. Store start index in low and end index in high.
  2. Here, without creating a temp variable to swap characters, we use xor(^).
  3. Traverse the input string “s”.
  4. Swap from first variable to end using xor.
  5. Return the final output string.

How do you split a string into two equal parts?

Algorithm

  1. STEP 1: START.
  2. STEP 2: DEFINE str = “aaaabbbbcccc”
  3. STEP 3: DEFINE len.
  4. STEP 4: SET n =3.
  5. STEP 5: SET temp = 0.
  6. STEP 6: chars = len/n.
  7. STEP 7: DEFINE String[] equalstr.
  8. STEP 8: IF (len\%n!=0) then PRINT (“String can’t be divided into equal parts”) else go to STEP 9.

How can I swap two strings in C# without using third variable?

Let’s see a simple C# example to swap two numbers without using third variable.

  1. using System;
  2. public class SwapExample.
  3. {
  4. public static void Main(string[] args)
  5. {
  6. int a=5, b=10;
  7. Console.WriteLine(“Before swap a= “+a+” b= “+b);
  8. a=a*b; //a=50 (5*10)

How do you swap two variables with a third variable in Java?

Java Program

  1. import java.util.*;
  2. class Swap_With {
  3. public static void main(String[] args) {
  4. int x, y, t;// x and y are to swap.
  5. Scanner sc = new Scanner(System.in);
  6. System.out.println(“Enter the value of X and Y”);
  7. x = sc.nextInt();
  8. y = sc.nextInt();

How to swap two strings in Java without third variable?

The simple approach to swap two strings in Java is by using a third variable. But, we can also swap two strings without using the third variable. Here is the simple program to swap two strings using a third variable. System.out.printf (“Before Swapping s1 = \%s and s2 = \%s. “, s1, s2);

How to swap two strings in Swift?

Swapping two strings usually take a temporary third variable. One of the approach to accomplish this is to concatenate given two strings into first string. Extract string 2 using substring (0, length (string1) – (string2)) i.e. in our case it will be substring (0, (11-4)).

How to swap two strings in C++?

Define two strings that need to be swapped. Concatenate both the strings and store it in first string. Extract the string from indexes 0 to length (string1) – (string2) using substring function and store it in string 2. Extract the string from index length (string2) till end using substring function and store it in string 1.
