Can local variable have same name as instance variable?
Answer: Yes — the scopes will not overlap so there will be two local variables, one per method, each with the same name.
Are instance variables initialized to a default value?
Instance variables have default values. For numbers, the default value is 0, for Booleans it is false, and for object references it is null. Values can be assigned during the declaration or within the constructor. Instance variables can be accessed directly by calling the variable name inside the class.
What is the difference between class and instance?
A class is a blueprint which you use to create objects. An object is an instance of a class – it’s a concrete ‘thing’ that you made using a specific class. So, ‘object’ and ‘instance’ are the same thing, but the word ‘instance’ indicates the relationship of an object to its class.
What happens if the local and global variable has the same name?
If a global and a local variable with the same name are in scope, which means accessible, at the same time, your code can access only the local variable.
Can static variable and local variable have same name?
Therefore it is possible. Neither of the local static int sVar; will be allocated on the stack (if there is such a concept at all), each function body is a separate block, which limits the scope of the local static variable.
Is instance variable global?
In an instance of a class the instance variables are available globally in the object. Anywhere in the object any instance method can get hold of any instance variable by just using @name_of_variable. This behavior of instance variables makes instance variables like a global constant.
Do local variables have default values?
The local variables do not have any default values in Java. This means that they can be declared and assigned a value before the variables are used for the first time, otherwise, the compiler throws an error.
Why do member variables have default values whereas local variables don’t have any default value?
Why do member variables have default values whereas local variables don’t have any default value? Ans. member variable are loaded into heap, so they are initialized with default values when an instance of a class is created. In case of local variables, they are stored in stack until they are being used.
Can Verilog tasks have access to global variables?
Verilog tasks can have access to global variables as well as local ones. Also, they can include non-blocking assignments. Thanks for contributing an answer to Stack Overflow!
Does Verilog support local variables in begin-end blocks?
Some tools however, may not support local variables defined inside a begin-end block. Verilog tasks can have access to global variables as well as local ones. Also, they can include non-blocking assignments. Thanks for contributing an answer to Stack Overflow! Please be sure to answer the question. Provide details and share your research!
What is the difference between an instance variable and local variable?
An instance variable is live as long as the object that contains that variable is live, while a local variable is live during the execution of that method/ code block. An instance variable (that is declared public) can be accessed within the class, whereas a local variable can only be accessed within the code block that it is declared.
How to change parameters with values in Verilog?
Consider the following example Verilog requires that if you wish to change, say third parameter in instantiation,then you must list 1st to 3rd parameter WITH values, even if their values did not change. If you wish to change only the second parameter, then you must list 1st and secod parameters with their values.
