Question
Select the correct answer
The default value of a static integer variable of a class in Java is:
- Options
- 1
- 0
- Garbage value
- Null
Solution
To determine the default value of a static integer variable in a Java class, we can analyze the properties of variable initialization in Java.
-
Break Down the Problem
We need to identify the default value of a static integer variable when it is not explicitly initialized.
-
Relevant Concepts
- In Java, static variables are initialized to their default values when the class is loaded.
- For primitive data types, each type has a specific default value. For
int, the default value is0.
-
Analysis and Detail
-
The options given are:
- 10
- -1
- Garbage value
- Null
-
Since we are dealing with a static integer variable, it will not be assigned a garbage value or
null(those are relevant for object references). -
The correct answer is based on the default initialization of integers in Java.
-
-
Verify and Summarize
The static integer variable, when uninitialized, will default to
0, but since0is not one of the options provided, none of the choices correctly represent the default value of a static integer variable in Java.
Final Answer
None of the options provided (10, -1, Garbage value, Null) represent the correct default value, which is 0.
