Java MCQ: What is the default value of a boolean variable in Java?
Answer:
Explanation:
In Java, when a boolean variable is declared as an instance variable (a member of a class) and is not explicitly initialized, it is automatically assigned a default value. For boolean variables, this default value is false.
This behavior is part of Java’s memory management, where the language ensures that all instance variables are initialized to a default value if not explicitly set by the programmer.
This helps prevent the use of uninitialized variables, which can lead to undefined behavior or errors. However, it is always a good practice to explicitly initialize variables to make the code more readable and maintainable.
