Explain the difference between an implicit type cast and an explicit type cast.
Implicit Type Cast
Automatic conversion of a value from one data type to another by the compiler.
Explicit Type Cast
A manual operation performed by the programmer to convert a variable from one data type to another. It's typically used when automatic type conversion is not possible or might lead to data loss.
- Acquire an understanding of data type conversion and discern the impacts of using implicit versus explicit casting techniques.

Final Answer :
A type cast takes a value of one type and produces a value of another type.Java supports two kinds of type casts: explicit and implicit.Java performs an implicit type cast automatically.This can be seen in the declaration of a variable of type double that is assigned an integer value.
double castExample = 72;
The integer value assigned to the variable castExample is automatically converted to a floating point number.The number assigned to castExample is converted to 72.0.
An explicit type cast occurs when the programmer explicitly forces a value of one type into a value of another type.In the example that follows,the value 72.5 is explicitly cast into an integer value.
int castExample = int)72.5;
double castExample = 72;
The integer value assigned to the variable castExample is automatically converted to a floating point number.The number assigned to castExample is converted to 72.0.
An explicit type cast occurs when the programmer explicitly forces a value of one type into a value of another type.In the example that follows,the value 72.5 is explicitly cast into an integer value.
int castExample = int)72.5;
