Question

How is implicit conversion different from explicit conversion?

Answer 1

In Java, type conversion can be implicit or explicit.

1. Implicit: In a mixed expression, the result's data type is automatically changed, without the user's input, to the highest type possible in the expression. Implicit type conversion/coercion is the term used to describe this type of conversion scheme.
   1. Example: 
      int a;
      long, c;
      c = a + b;

   2. In this example, a is automatically transformed to the long data type.

2. Explicit: This method of type conversion allows users to transform one data type to another based on their preferences. This signifies the user expects the system to return the desired data type.
   1. Example: 
      int a, b;
      float x = (float) a + b;
