The for-loop solution should be the easiest, as you can use the Math.floor function to get the start of your desired list: for (double d = Math.floor(start); d <= Math.ceil(end); d += 1.0) list.add(d); 13 solved Filter element in array of doubles
you can try splitting using this regex ([\d,]+|[a-zA-Z]+ *[a-zA-Z]*) //note the spacing between + and *. [0-9,]+ // will search for one or more digits and commas [a-zA-Z]+ [a-zA-Z] // will search for a word, followed by a space(if any) followed by another word(if any). String regEx = “[0-9,]+|[a-zA-Z]+ *[a-zA-Z]*”; you use them like this … Read more
Rounding mode to round towards negative infinity. If the result is positive, behave as for RoundingMode.DOWN; if negative, behave as for RoundingMode.UP. Note that this rounding mode never increases the calculated value. It is just matter of whole number and its position against number chart. From here you can see javadocs. public static int round(float … Read more

I think this may be primarily opinion based. The way I see it, keeping things simple is sometimes the smarter way to design. To have the compiler accept some code that the compiler currently doesn’t accept, that would (at a minimum) require more complexity. The compiler would have the additional burden of determining which constructs … Read more
you need to add a button to your .xml file like this : <Button android:layout_width=”match_parent” android:layout_height=”wrap_content” android:text=”Goal” android:layout_margin=”8dp” android:onClick=”add1ForTeamA” android:id=”@+id/Three_Button_B”/> then if you will notice that the android:onclick has been set to the add1ForTeamA method. Go to the mainActivity.java file and add this method `public void addOneForTeamA(View view) { scoreTeamA = scoreTeamA + 1; displayForTeamA(scoreTeamA); … Read more

For loops are iterative statements that repeat a certain block of code , on the other had, if statements are the conditional statements that perform decision making situations. You cannot go from one to other as just as you can’t go from repeating stuff and making decisions in most cases. However, if you wanna repeat … Read more
Comparisons are similar to the ordering that one might find in a dictionary. The return of this method is an int which can be interpreted as follows: returns < 0 then the String calling the method is lexicographically first (comes first in a dictionary) returns == 0 then the two strings are lexicographically equivalent returns … Read more
The reason that my server keeps crashing is because it runs out of memory. (From: @Jon Skeet) The fact that you’re looping over a collection and conditionally adding to it looks suspect to me. It’s possible that it’s just looping forever, because it adds an item, then finds that item and adds another, then adds … Read more
You should only pass something as an argument if you need prior information to do what you want to do, so the parameters of flatfee and co. should be empty: flatFee() { // code here } you then declare a as a local variable: flatFee() { double a; // do stuff return a * 5.0; … Read more
Your code has some confusion in its handling of the ‘{‘ and ‘}’ characters. It should be entirely parallel to how you handle ‘(‘ and ‘)’. This code, modified slightly from yours, seems to work properly: public static boolean isParenthesisMatch(String str) { if (str.charAt(0) == ‘{‘) return false; Stack<Character> stack = new Stack<Character>(); char c; … Read more
Trying to enumerate all the different possible strings in the array is generally a bad idea and not the correct way to write your program. Sure your example works, but what would happen if your set of possible strings was not just {‘this’, ‘is’, ‘a’, ‘test’}, but instead had say 10000 elements? What if you … Read more
You set a to a random number between 0 and 5. You set b to a random number between 0 and 5 – a You set c to a random number between 0 and 5 – a – b You set d to 5 – a – b – c As a result, you get … Read more
I don’t see much here which really surprises me. Most likely, the end of the file gets reached in your while loop with the first call to Scanner#nextLine(). Then, you make a second call which throws the exception since there is no more content to read. while (reader.hasNextLine()) { // during the last iteration, this … Read more
