// Java program swap two nibbles // of a given byte import java.util.Scanner; public class Main { static byte swapTwoNibbles(byte val) { byte num; num = (byte)((val & 0x0F) << 4 | (val & 0xF0) >> 4); return num; } public static void main(String[] args) { Scanner SC...
In this article, we discussed two different methods for swapping elements of a Vector in Java: using a temporary variable and using the Collections.swap() method. Both approaches have their own benefits; using a temporary variable offers more control over the swapping process, while Collections....
Approach 1: Using a Temporary VariableYou can swap two numbers by using a temporary variable to store one of the values while you assign the new value to the other variable.ExampleThe following example demonstrates swapping two integers using a temporary variable:...
Suppose you have two variables x and y and you want to swap their values. The usual way to do this is using another temporary variable: temp = x; x = y; y = temp; However, the interchange of two variables can be done without the temp variable: ...
Swap Two Values Using a Temporary Variable in Python In this method, a temporary variable is used to swap two values. Consider two variables,aandband a temporary variable,temp. First, the value ofawill be copied totemp. Then the value ofbwill be assigned toa. Lastly, the value oftempwill...
