What happens if you don't initialize an instance variable of any of the primitive type in java?
Java by default initializes it to the default value for that primitive type. Thus an int will be initialized to 0(zero), a Boolean will be initialized to false.
What does a Java Boolean type variable declared but not yet initialized contain when its class is instanciated?
If it is a class or instance variable, it gets the default value of false. If it is a local variable (inside a method), it doesn't have a value until you explicitly set one.
What value is assigned to extern variable?
Default initial value of extern integral type variable is zero otherwise null.
What data or variable type is used for variables that will only have the values true or false?
Boolean
Can you add a variable with a number?
Yes, IF the variable has been declared, has a value, and is of a numerical type such that your addition operator can perform the operation on the number and the value of that type variable. The compiler or interpreter will look up the variable's value, substitute it for the variable, and perform the addition just as if your statement used two numbers. First example: If your number is an integer and your variable is of type real, almost any addition operator can successfully add the two. Second example: If your number is a real and your variable is a character type (with a value, say, of "Smith"), the addition will obviously fail. In many languages, however, variables of type Boolean may be handled arithmetically, as the value True equals 1 and False is zero.

What is default values of different primitive data types?
in integral data types default value=0 in decimal type default value is 0.0 in boolean default value is fa

Default initial value of extern integral type variable is zero otherwise null.
How does the absolute beginner to Browser-side scripting supposed to know what boolean or string means?
Boolean means yes or no, true or false, 0 or 1. There can only be 2 alternatives in boolean. In JavaScript there is a function typeof which will show whether variable is boolean, string, integer or any other. I am providing a few examples. Try those and you will understand what type of variable is providedvar a = 12;alert("Variable is of type: "+typeof(a));var a = "hello";alert("Variable is of type: "+typeof(a));
What is a name for a variable used for storing true false statements?
Usually, the name of the variable can be most anything. This type of variable is called a LOGICAL variable.
What is the Boolean operator that is appropriate to use?
Boolean is a type, not an operator and can have the value of either TRUE or FALSE
What data or variable type is used for variables that will only have the values true or false?
Boolean

Which is the default variable storage class type in a function?
Everything is an object, and "typed" based on assignation. Your variable will be given a class when you declare it to be something, and the class will depend on what value you give the variable. It is always an object though, and its class may change if you change its value.
What is the default data type for Visual Basic?
A variable has a data type such as integer, string, double. A data type tells the variable to only store values that are a particular data type, so you can only store numbers without decimal points in an integer variable, and only characters such as "ABCD" in a string variable.
What is static variable in the class in cpp?
Static member variables of a class are variables that are local to the class within which they are declared. That is, each instance of the class (each object) shares the same common member variable. Changing that variable's value in one instance will change it for all instances. Contrast with a non-static member variable where each instance of the class has its own independent variable, scoped to the object itself (not the class of object).
