Can a method have two return types?

No, you don't have two return types.

Can a method return two types?

You can return only one value in Java. If needed you can return multiple values using array or an object.

How many return types can a method have?

A method can return at most one value. The method signature specifies the return type, which can be a primitive (int, double, boolean), a class (String, Turtle, etc), or void.

Can a method have two return statements?

A function can have more than one return statement, but only ever run one based on a condition.

Can a method have two return types in C#?

Methods in C# return only one value. This value can be an object with multiple fields. Many options are available for returning multiple values from a method.

Can we override a method by using same method name and arguments but different return types in Java?

Can a method return two strings?

A method has a single return type, so unless you package the two Strings in some class and return that class (or put the two Strings in a String array or some other container of Strings), you can only return one String.

Can a method return two values in C?

In C or C++, we cannot return multiple values from a function directly. In this section, we will see how to use some trick to return more than one value from a function. We can return more than one values from a function by using the method called “call by address”, or “call by reference”.

Should a method only have one return statement?

It is sometimes said that a method should have only one return statement (i.e. one exit point) and that to code using more than one return per method is bad practice. It is claimed to be a risk to readability or a source of error. Sometimes this is even given the title of the “single exit point law”.

Should a method have multiple return statements?

The question is whether a method may have multiple return statements or just one. The answer may surprise you: In a pure object-oriented world, a method must have a single return statement and nothing else.

Can a method contain any number of return statements?

Explanation: True, A function may have any number of return statements each returning different values and each return statements will not occur successively.

How to set two return types in Java?

Do all methods need a return type?

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 type of data returned by a method must be compatible with the return type specified by the method.

Does every method need a return type?

Every Method has a return type whether it is void, int, double, string or any other datatype. The getReturnType() method of Method class returns a Class object that represent the return type, declared in method at time of creating the method.

How do I return two data types?

Can two methods with same name have different return types?

The java documentation states: The compiler does not consider return type when differentiating methods, so you cannot declare two methods with the same signature even if they have a different return type.

What is a return type in a method?

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.

Can a method return multiple types Java?

Java doesn't support multi-value returns. We can use following solutions to return multiple values. We can return an array in Java. Below is a Java program to demonstrate the same.

Can we create method to have multiple return type parameters?

You cannot have two RETURNING parameters, just one.

What is the problem with multiple return statements?

▚Readability

Sticking to a single return statement can lead to increased nesting and require additional variables (e.g. to break loops). On the other hand, having a method return from multiple points can lead to confusion as to its control flow and thus make it less maintainable.

Should two return statements never occur in a function?

8. In a function two return statements should never occur. Explanation: No, In a function two return statements can occur but not successively.

Which method returns value as double?

The doubleValue() method returns the double value represented by this object.

How many values can a function return?

A function can only return a single object.

Can methods return a value of type Boolean?

The data type of the return value must match the method's declared return type; you can't return an integer value from a method declared to return a boolean.

Can a method throw 2 exceptions?

You can't throw two exceptions. I.e. you can't do something like: try { throw new IllegalArgumentException(), new NullPointerException(); } catch (IllegalArgumentException iae) { // ... }

Can a function return multiple variable types?

Create a function getPerson(). As you already know a function can return a single variable, but it can also return multiple variables.
