What is the default value for an Integer object if no value is provided at initialization?

  1. 0

  2. -1

  3. 1

  4. Undefined

The correct answer is: 0

Integer objects are numeric objects that are used for storing numerical values in programming. When an Integer object is initialized, a value can be provided or the object can be left without a value. If no value is provided at initialization, the default value for an Integer object is 0. This is because 0 is considered the neutral number in mathematics and is often used as the default value for numerical operations. Options B, C, and D may seem like plausible answers, but these values are not commonly used as default values for Integer objects in programming. Option B, -1, is the negative counterpart of 0 and is also used frequently in programming, making it an unlikely choice for a default value. Option C, 1, is the simplest positive numeric value and is often used for incrementing and counting, making it a valuable value that is unlikely to be used as a default. Option D
