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.

  1. Break Down the Problem

    We need to identify the default value of a static integer variable when it is not explicitly initialized.

  2. 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 is 0.
  3. Analysis and Detail

    • The options given are:

      1. 10
      2. -1
      3. Garbage value
      4. 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.

  4. Verify and Summarize

    The static integer variable, when uninitialized, will default to 0, but since 0 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.
