In Java, converting an int to a double involves casting the int value to a double type. This conversion allows you to preserve the numeric value while changing the data type from an integer to a floating-point number.
Here's an example code snippet that demonstrates how to convert an int to a double:
int myInt = 10;
double myDouble = (double) myInt;
System.out.println("Original int value: " + myInt);
System.out.println("Converted double value: " + myDouble);
In this example, we have an int variable named myInt with a value of 10. To convert it to a double, we use the (double) casting operator before the myInt variable. The value of myInt is then assigned to the myDouble variable, which is declared as a double.
Finally, we print both the original int value (myInt) and the converted double value (myDouble) using the System.out.println method.
When you run this code, the output will be:
Original int value: 10
Converted double value: 10.0
As you can see, the int value of 10 is successfully converted to a double value of 10.0. The fractional part is added, even though it is zero in this case, to conform to the data type of double, which represents floating-point numbers.
