Any method declared void doesn't return a value. It does not need to contain a return statement, but it may do so.
What is the return type of a method that does not returns any value? a) intb) floatc) voidd) doubleView AnswerAnswer: cExplanation: Return type of an method must be made void if it is not returning any value.
A constructor doesn't have any return type. The data type of the value retuned by a method may vary, return type of a method indicates this value. A constructor doesn't return any values explicitly, it returns the instance of the class to which it belongs.
However, as the definition of Constructor goes, it is used to initialize an object of the class. So implicitly, they return the current instance of the class whose constructor it is. Therefore, Implicit return type of a class constructor is class type itself.
In computer programming, the return type (or result type) defines and constrains the data type of the value returned from a subroutine or method. In many programming languages (especially statically-typed programming languages such as C, C++, Java) the return type must be explicitly specified when declaring a function.
a bool value9. What is the return type open() method? Explanation: open() method returns a bool value indicating whether the file is opened or some error has occurred. 10.
Constructor is not like any ordinary method or function, it has no return type, thus it does not return void. Constructors don't create objects.
No, constructor does not have any return type in Java. Constructor looks like method but it is not. It does not have a return type and its name is same as the class name. Mostly it is used to instantiate the instance variables of a class.
A return statement causes the program control to transfer back to the caller of a method. Every method in Java is declared with a return type and it is mandatory for all java methods. A return type may be a primitive type like int, float, double, a reference type or void type(returns nothing).
The Implicit return type of constructor is void.
Explanation: Constructors does not have any return type, not even void.
Therefore, the return type of a constructor in Java and JVM is void.
A method's local variables exist only while the method is executing. This is known as the lifetime of a local variable. When the method begins, its local variables and its parameter variables are created in memory, and when the method ends, the local variables and parameter variables are destroyed. This means that any value stored in ...
If a parameter variable is changed inside a method, it has no effect on the original argument.
True or False: No two methods in the same program can have a local variable with the same name. True or False: It is possible for one method to access a local variable that is declared in another method. True or False: You must have a return statement in a value-returning method.
