If the return type must be the type of the class that implements the interface, then what you want is called an F-bounded type: public interface A<T extends A<T>>{ public T b(); } public class C implements A<C>{ public C b() { … } } public class D implements A<D>{ public D b() { … … Read more
The second and third arguments to the ternary operator are expressions, not statements. return a is a statement
Yes* Yes, usually (and in your case) it does break out of the loop and returns from the method. An Exception One exception is that if there is a finally block inside the loop and surrounding the return statement then the code in the finally block will be executed before the method returns. The finally … Read more
Finally always executes. That’s what it’s for, which means its return value gets used in your case. You’ll want to change your code so it’s more like this: function example() { var returnState = false; // initialization value is really up to the design try { returnState = true; } catch { returnState = false; … Read more
Can someone explain a void return type in Java? The void type is used to declare that a method does not return a value. Couldn’t you just make the return type String and set the string equal to the parameter to make it show up when the method is called? Hypothetically “you” (or in this … Read more
return in a function means you are leaving the function immediately and returning to the place where you call it. So you should use return when you are 100% certain that you wanna exit the function immediately. In your example, I think you don’t want to exit the function until you get the final value … Read more
You’re pretty much there. You can remove all globals, then just store the values returned from each function to local variables, and pass them in to new functions. The only other changes I’ve made below are: Breaking out of the evaluation loop if the answer is guessed correctly. Printing a message if no guess is … Read more
This is not possible. Javascript runs on the UI thread; if your code waits for the server to reply, the browser must remain frozen. Instead, you need to return the value using a callback: function get_char_val(merk, callback) { var returnValue = null; $.ajax({ type: “POST”, url: “char_info2.php”, data: { name: merk }, dataType: “html”, success: … Read more
In most cases, returning early reduces the complexity and makes the code more readable. It’s also one of the techniques applied in Spartan programming: Minimal use of Control Minimizing the use of conditionals by using specialized constructs such ternarization, inheritance, and classes such as Class Defaults, Class Once and Class Separator Simplifying conditionals with early … Read more
The difference is that they DO DIFFERENT THINGS! ‘Return value’ does 2 things: 1. It sets the function return value at that point 2. It immediately exits the function No further code in the function executes! ‘Functionname = value’ does 1 thing: 1. It sets the function return value at that point Other code in … Read more
