Question

Hey guys
.
Explain the work of return statement in Java

Answer 1

return statement is used to return something
as like in this example
public class Program
{
static int x; // try to make the x variable being private: and get the error message mean of private static :
public static void main(String[] args) {
System.out.println(X.fun()); // try to call as this fun(): why it's required to call the static variable and method so good practice to call the static variable and method with class name.
}
}
class X{
static int fun(){
Program.x++; // try to replace the Program and seen what happend: answer why it is required to call static variable and method with class name :
return Program.x;// return the value of x
}
}

when the method fun is call then it's return the value of x:: for returning something we use return keyword and the return type before the method name as int is return type of fun method

Answer 2

Hii....

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.
