Join Peggy Fisher for an in-depth discussion in this video Understanding implicit and explicit conversion, part of Up and Running with Java.
- Sometimes it is necessary…to change the data type of a variable.…There are two ways to accomplish this change,…using implicit and explicit data conversion.…Although we already talked about the fact…that Java is a strictly data-typed language,…and it is really important to declare each variable…with a specific data type,…the type of data stored at that variable name…can be changed both temporarily and permanently…using something called implicit and explicit conversion.…An implicit conversion occurs…when an equation has more than one data type,…such as an integer and a double.…
The computer must decide which data type to use…for the result of the equation.…Implicit conversions always use…the largest data type from the equation.…For example, if you multiply…10 * 15.75,…the result should be 157.50.…We automatically know that we wanna include…the fractional portion of our result.…Another good example of this situation…is probably finding the average…of a group of numbers.…If the numbers are integers,…you still wanna make sure…
