Question

Java assigns a default value to a data member of a class if the data is not initialized. True or False?

Answer 1

Java does assign a default value to uninitialized class data members, with the type of the value dependent on the data type.

Step-by-step explanation:

True, Java does assign a default value to class data members that are not explicitly initialized. Each data type has a different default value:

• int: 0
• double: 0.0
• boolean: false
• Object references (including arrays): null

This behavior helps prevent errors that might arise from uninitialized variables. However, it's important to intentionally initialize class members to avoid relying on these default values and to ensure clarity in your code.
