Consider using a while-loop: import java.util.Random; class Sequence { public static void main(String[] args) { Random r = new Random(); int count = 0; int num = -1; System.out.println(“The sequence is:”); while (num != 0) { num = r.nextInt(10); System.out.print(num + ” “); count++; } System.out.printf(“%nThe length of the sequence is: %d%n”, count); } } … Read more
Try this. do{ System.out.print(“Please enter an integer or -1 to stop: “); input=Integer.parseInt(scan.nextLine()); boolean flag = true; for(int i=0; i<A.length; i++){ if(A[i].equals(input)) { System.out.println(“Duplicate input. Please enter another value: “); flag = false; break; } } if(!flag) { continue; } if(input != -1) //if input is Display.userInput(input); } while(input != -1); 1 solved Java: Finding … Read more
Creating DateTime variables and summing them is an approach, but I assume you’re new to Java and give you basic answer to warn you up for some coding and not to go the easy way: String[] timesSplit = times.split(” | “); int hour = 0; int minute = 0; for(int i = 0; i < … Read more
No, you don’t make variables for an animal’s traits, because those traits don’t change (disregarding evolution). Firstly, you need a decent book on object-oriented design, rather than asking us to help. Take some initiative and do some research. For the moment, how about just implementing some basic polymorphic boolean functions like IsTerrestrial(), IsAquatic(), etc… Maybe … Read more
You can think of the problem as the following: each progressive line includes the content of the previous line plus another odd number. Therefore, it would make a lot of sense to always store the content of the previous line under a String variable, perhaps. Now to find every odd number, start with the number … Read more
Q. If you compile and execute an application with the following code in its main() method: Why ” s” is created two objects [duplicate] solved Q. If you compile and execute an application with the following code in its main() method: Why ” s” is created two objects [duplicate]
I think you can refer the Location API to calculate the distance between your current location and another one. http://developer.android.com/reference/android/location/Location.html I think you can one of these methods: public static void distanceBetween (double startLatitude, double startLongitude, double endLatitude, double endLongitude, float[] results) public float distanceTo (Location dest) 1 solved Android | Java | check if … Read more
In Groovy, you can use the following check (assuming text is the variable holding the string you provided in the question): if (text=~/Server returned HTTP response code: 503\b/){ println “503 code detected” } else { println “503 code not detected” } But it also seems you can just use contains: if (text.contains(‘HTTP response code: 503 … Read more
Try removing the android prefix in <item name=”android:windowNoTitle”>true</item> i.e replace it with <item name=”windowNoTitle”>true</item>. Also replace <style name=”MyMaterialTheme.Base” parent=”Theme.AppCompat.Light.DarkActionBar”> with <style name=”MyMaterialTheme.Base” parent=”Theme.AppCompat”> , the Light.DarkActionBar part is unnecessary as you are specifying windowActionbar as false and windowNoTitle as true and setting action bar in activity. Also one more thing, ActionBarActivity is deprecated in revision … Read more
The Java locale framework supports internationalization of some common forms of date / time, numbers, currency and so on. For date / time values the set of predefined formats is described in the Java Tutorial: Using Predefined Formats. Unfortunately, “year and month” is not one of the formats. This leaves you with only one option. … Read more
The & and | operators are, respectively the AND bitwise and OR bitwise. The >> and << are the bit shifting. solved Meaning of some operator in java [closed]
“but they all fall from the top of the screen where y=0” This coincides with your requirement (which you mention a few lines above) so this is fine. You just need to make the x value random. So keep y=0 as a constant, and just make the x random. Look at this class: Random Use … Read more
It depends on the size of the objects you are recursing. If you are doing recursion over objects that are already in memory, memory impact will be neglible because it’s simply using the same objects that are already in memory over and over. Just see which objects/variables you can re-use to keep memory footprint low. … Read more
Are all the buttons currently in the same class? Because if so, you can just make a method that does the work, and call it for each button, passing as method arguments any variables that change from button to button. If not, you can still make a method, but you’ll just have to make it … Read more
In your outer while loop you need this: overtime = 0; if (hoursWorked>8) overtime = (hoursWorked-8)*(rateOfPay*1.5) – (hoursWorked-8)*rateOfPay; // Calculate OVERTIME HOURS sets the overtime to zero for each iteration, and you’ll have to subtract the normal rate for overtime hours (otherwise you add them twice) and then you’ll have to add the overtime to … Read more
