3 / 10Java-variables and data typesHardJava

Which of the following assignments is guaranteed to compile without loss of precision?

  1. float f = 3.14;

  2. double d = 3.14f;

  3. int i = 3.14f;

  4. short s = 100000;

  5. byte b = 200;

Show answer & explanation

Correct answer

double d = 3.14f;

Explanation

A `float` can be assigned to a `double` without explicit cast because `double` has a larger range and precision (widening primitive conversion). The other options involve narrowing conversions that require an explicit cast or may lose information.
