What is the default value of a static variable of type int in Java if not explicitly initialized?

Correct option is B

In Java, static variables belong to the class rather than an instance and are initialized with default values if not explicitly set. For int variables, the default value is 0.
Example:

Important Key Points:
1. Default values for static variables are determined by the type:
· int: 0
· double: 0.0
· boolean: false
· Object references: null
2. static variables are stored in the method area of the JVM.
Knowledge Booster:
· null: Applicable for object references, not primitive types.
· -1: Not the default value for any type in Java.
· undefined: Java does not use the concept of "undefined"; default values are well-defined.
· garbage value: Java does not allow uninitialized variables to have garbage values.
