Kirat[ad_1] So far, you have the right idea. I am going to assume based on your syntax, that you are using an array. Your get() method looks good, but you are missing some code from your remove() method. public int remove(int index){ //check for out-of-bounds if(index < 0 || index >= size) //assumes size is … Read more

[ad_1] Not exactly mine but just so people can clearly see for future learning and reference, I have subsequently received this answer from a member of the cod_ae_cademy pro team named Elise (:~)): “in this case it seems like [the codaecademy engineers] have a security setting to require that script [be called in directly from … Read more
[ad_1] The main method must be declared public, static, and void; from JLS 12.1.4: The method main must be declared public, static, and void. It must specify a formal parameter (ยง8.4.1) whose declared type is array of String. Therefore, either of the following declarations is acceptable: public static void main(String[] args) public static void main(String… … Read more
[ad_1] I would suggest neither, rather I would suggest this List<int> data = Enumerable.Range(0, 10000000).ToList(); int j = -1; // Method 1 while (++j < data.Count) { // do something } int j = 0; do { //anything } while (++j<data.count); pre-increment operation is faster than post, although a small performance advantage 3 [ad_2] solved … Read more
[ad_1] You need to use add the OnRatingBarChangeListener to handle the OnRatingBarChanged event. Add the necesary code to the onBindViewHolder method: @Override public void onBindViewHolder(@NonNull FoodViewHolder foodViewHolder, int i) { FoodItem currentItem = arrayList.get(i); foodViewHolder.viewHolderImageView.setImageResource(currentItem.getFoodImage()); foodViewHolder.viewHolderTextView.setText(currentItem.getFoodName()); foodViewHolder.viewHolderRatigBar.setRating(currentItem.getFoodRating()); foodViewHolder.viewHolderRatigBar.setOnRatingBarChangeListener(new RatingBar.OnRatingBarChangeListener(){ @Override public void onRatingBarChanged(RatingBar ratingBar, float rating, boolean fromUser){ currentItem.setFoodRating(rating); } } } NOTE: The value … Read more
[ad_1] What I think you’re trying to achieve is that when you call your method “horn” with some parameter it has to either use “Beep!” or “Boop!”. First of: void horn(a,b) Is not a valid function signature in Java, in a java function you always have to specify what type the input you’re providing is. … Read more
[ad_1] void::speak(); //THE GLOBAL SCOPE HAS NO SPEAK It’s interpreting this as void ::speak() where leading an identifier (a name) with :: indicates to C++, “Look in the global scope of all names”. :: is the “scope resolution operator” In the header file, you should just use void speak(); since C++ sees it inside your … Read more
[ad_1] First of all, what you are doing is fragile: If the InputStream was not a FileInputStream it would fail. If a future Java releases changes the internals of FileInputStream, it may fail. It is likely to fail if your code is sandboxed. It would be much better to keep / pass the value of … Read more
[ad_1] Youc can set a position to image using Jquery See fiddle //set a begining position to img var slider = $(“.slider”)[0]; var sliderPos = slider.value / slider.max; var pixelPostion = slider.clientWidth * sliderPos; $(“.img”).css(“left”,pixelPostion-7 + “px”); //set a position to img when slide move $(document).on(‘input’, ‘.slider’, function() { var slider = $(“.slider”)[0]; var sliderPos … Read more
[ad_1] Very often it is used just to write shorter (thus writting code faster?) and more readable code. But trying to force => whenever you can may have negative effect on readability of yours code. 7 [ad_2] solved using Expression-bodied members improve some performance? [closed]
