Question

Which keyword is used to declare instance variables?

a) static
b) accessKeyword
c) dataType
d) varName

Answer 1

Instance variables are declared without a specific keyword, identified as non-static fields within a class. They are initialized when an object of the class is created, and their declaration includes an access modifier, data type, and variable name.

Step-by-step explanation:

The keyword used to declare instance variables in Java is none of the options provided directly. Instance variables are not declared with a special keyword like static, but they are identified as non-static fields that belong to an instance of a class. These variables are declared within a class outside any method, constructor or block, and are initialized when a class instance (an object) is created. Typically, an instance variable declaration includes an access modifier (such as public, protected, or private), optionally followed by other modifiers, and then it is followed by a data type and variable name. For example:

public class Example {
private int instanceVar; // Instance variable declaration
}

Here, private is the access modifier, int is the data type, and instanceVar is the variable name.
