How to swap two integer variables in Java?
Swapping two values usually requires a temporary variable to store one of the values. However, it is possible to swap two integer variables without using any additional storage. This can be done by using arithmetic operators or bitwise operators.
Temporary Variable Swap
The most common way to swap two variables is to use a temporary variable. For example, if we want to swap x and y, we would do the following:
Arithmetic Operator Swap
However, this method requires the use of an additional variable. We can also swap two variables without using a temporary variable by using arithmetic operators. For example, if we want to swap x and y, we can do the following:
Bitwise Operator Swap
It is also possible to swap two variables without using a temporary variable or arithmetic operators. This can be done by using bitwise operators. For example, if we want to swap x and y, we can do the following:
Both of these methods are efficient and do not require the use of an additional variable.
