In this program we are going to Swap Two Numbers
public class SwapNumbers {
public static void main(String[] args) {
float first = 1.20f, second = 2.45f;
System.out.println("Before swap:");
System.out.println("First number = " + first);
System.out.println("Second number = " + second);
// Value of first is assigned to temporary
float temporary = first;
// Value of second is assigned to first
first = second;
// Value of temporary (which contains the initial value of first) is assigned to second
second = temporary;
System.out.println("After swap:");
System.out.println("First number = " + first);
System.out.println("Second number = " + second);
}
}
Code language: JavaScript (javascript)
What You get as Output , After running the program
Before swap: First number = 1.2 Second number = 2.45 After swap: First number = 2.45 Second number = 1.2
