Question
The default value of a static integer variable of a class in Java is:
- Options
0
Garbage value
1
-1
Null
Solution
Break Down the Problem
- Identify the nature of the variable: It’s a static integer variable in a Java class.
- Determine what the default value for this type of variable is in Java.
Relevant Concepts
- In Java, class variables (static variables) are initialized to default values if not explicitly initialized.
- The default value for numeric primitives, including
int, is0.
Analysis and Detail
- Static integer variables in Java belong to the class rather than to instances of the class.
- Since it's a static variable and it's an integer, it will hold a default value of
0until initialized to another value.
Verify and Summarize
Based on Java's rules for variable initialization:
- The static integer variable starts at
0. - Other options like "Garbage value," "-1," and "Null" are incorrect for a static integer.
Final Answer
The correct answer is 0.
