Answer
Initial values prevent usage of uninitialized variables.
An uninitialized variable can lead to unpredictable behavior or runtime errors. Java requires variables to be initialized before use. For example, 'int quantity = 0;' ensures 'quantity' starts at zero, avoiding accidental use of undefined values in calculations.
