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 since0
is 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
.
