Can you declare the same instance variable name more than once in a class?

It is illegal to declare the same variable name more than once within a block. If you give the same name to a class’s instance field and to a local method variable, the instance variable overrides the method’s local variable.

Can you declare two variables with the same name?

It’s not possible, an if statement has no special scope, so you can’t have two variables with the same name within the same scope and access both, the latter will overwrite the former, so they should have different names.

Can you have 2 variables with the same name Java?

Answer: Yes — the scopes will not overlap so there will be two local variables, one per method, each with the same name.

Can you have two variables within the same program with the same name?

Said in simple terms, if multiple variables in a program have the same name, then there are fixed guidelines that the compiler follows as to which variable to pick for the execution.

What will happen if the instance variable name and the local variable name are same?

In other words, when a local variable has the same name as one of the instance variables, the local variable shadows the instance variable inside the method block. In the following example, there is an instance variable named x , and inside method printLocalVariable() , we are shadowing it with the local variable x .

Which type of variable can have the same name in a different?

2. Which type of variables can have the same name in a different function? Explanation: None.

Can we declare local two variables in a function with same name but different data type co3?

You can declare local variables with the same name as a global variable, but the local variable will shadow the global. As long as your local a is in scope, the symbol a refers to your local variable.

When two variables have the same name but one is global and one is local the JavaScript program will not run?

When a global and local variable share the same name, a JavaScript program will not compile. Functions are made up of two parts, the name and the parameters. How do you get an answer from a function? You return it.

How does Java deal with variables having the same name?

It’s completely fine because methods and variables are called differently. If you write “this. sameName” when you are supposed to write “this. sameName()” and vice-versa at some place in the program then annihilation of the code has just begun.

Can we declare local variables with same name in different functions?

How do you distinguish between instance variables and local variables for a method?

The main difference between instance variable and local variable is that instance variable is a variable that is declared in a class but outside a method, while a local variable is a variable declared within a method or a constructor.

Can instance variables be declared at the class level?

Instance variables can be declared at the class level before or after use. Access modifiers can be given for instance variables. The instance variables are visible for all methods, constructors, and block in the class. Normally, it is recommended to make these variables private (access level).

Can you have two variables with the same name?

Yes — the scopes will not overlap so there will be two local variables, one per method, each with the same name. Instance Variable and Local Variable. with Same Name. Although it is usually a bad idea, you can declare a formal parameter or a local variable with the same name as one of the instance variables.

Can a class file have more than one variable named a?

For instances, a valid class file can have several variables named ‘a’, as long as they have different types. If you decompile such a class, the source code you get will not be valid.

What are instance variables in C++?

Instance variables hold values that must be referenced by more than one method, constructor or block, or essential parts of an object’s state that must be present throughout the class. Instance variables can be declared at the class level before or after use. Access modifiers can be given for instance variables.
