- Return_type abstract "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.In the Java example: the return type is int. The program can therefore rely on the method returning a value of type int. Various mechanisms are used for the case where a subroutine does not return any value, e.g., a return type of void is used in some programming languages: Returning a Value from a MethodA method returns to the code that invoked it when itcompletes all the statements in the method,reaches a return statement, orthrows an exception (covered later),whichever occurs first.You declare a method's return type in its method declaration. Within the body of the method, you use the return statement to return the value.Any method declared void doesn't return a value. It does not need to contain a return statement, but it may do so. In such a case, a return statement can be used to branch out of a control flow block and exit the method and is simply used like this:return;If you try to return a value from a method that is declared void, you will get a compiler error.Any method that is not declared void must contain a return statement with a corresponding return value, like this:return returnValue;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.The getArea() method in the Rectangle Rectangle class that was discussed in the sections on objects returns an integer: // a method for computing the area of the rectangle public int getArea() { return width * height; }This method returns the integer that the expression width*height evaluates to.The getArea method returns a primitive type. A method can also return a reference type. For example, in a program to manipulate Bicycle objects, we might have a method like this: public Bicycle seeWhosFastest(Bicycle myBike, Bicycle yourBike, Environment env) { Bicycle fastest; // code to calculate which bike is // faster, given each bike's gear // and cadence and given the // environment (terrain and wind) return fastest; }".
