You could do something like the following: int total = 100; int i = 0; // You should use a more specifc type than Object if you can Map<Integer, Object> m = new HashMap<Integer, Object>(); while (i < total) { Object o = //what you want to put into the HashMap on each iteration m.put(i, … Read more
The obvious way: Picture temp; temp = Picture1; Picture1 = Picture2; Picture2 = temp; solved Re-referencing objects
Try this: ((getTkphValue().doubleValue()/getTkphMaxValue().doubleValue())*100) Before you do, make sure that tkphMaxValue and tkphValue are not null. solved Divide values from a class extending number
.Yes. Calendar.getInstance().get(Calendar.MINUTE) returns the current minute count within the hour. To find the nearest 10 min, assuming minutes contains the current minute count, you do: int nearest = ((minutes+5) / 10)*10 % 60; It uses integer division by 10 to “round down” to nearest 10, but first 5 is added such that 25 becomes 30, … Read more
public static int isGreater(int limit, int[] data){ int overLimit = 0; for(int k = 0; k < data.length; k++){ if (data[k] > limit) overLimit++; } return (overLimit/data.length)*100; } By keeping a running calculation of the numbers that are over and under the limit, you can calculate what percentage of the overall list was greater than … Read more
This code should work. String info = “You have 2$ on your public transport card and one active ticket which expires on 2017-08-09 23.59”; Pattern pattern = Pattern.compile(“(\\d\\$).*and\\s(.*)”); Matcher m = pattern.matcher(info); while (m.find()) { System.out.println(“First Group: ” + m.group(1) + ” \nSecond Group: ” + m.group(2)); } Just like Andreas said before, you should … Read more
I will try to explain this in as simple terms as possible. You write your Java code and save it in a .java file. The .java file is then turned into a .class file by the Java compiler. Now what does this .class file contain? Does it contain machine code that a processor can directly … Read more
The code you’ve made is incomplete as @user681574 stated, so unfortunately your question will be answered in a vague way. It seems like you have to make objects appear when the player has successfully logged in as it is the easiest way possible. Another way is to make the players not able to register clicks/keys … Read more
In the OnTaskCompleted before jarray = utils.getJarrayFromString(result); add a log entry with Log.i(DEBUG,result); I am suspecting that you are getting a null value as result if(result!=””) does not ensure a valid value. Cheers 1 solved JSON Parsing Error – String cannot be converted to JSONArray
A couple of comments regarding your code. You should mark your fields as private and then access to them trough getter/setter. class RF { private final String nom; private final String ref; private final String num; I don’t know why they are final (I don’t hink they should) anyway. Then RF n = (RF) jComboBox1.getSelectedItem(); … Read more
If we use a valid URL instead of wow (say, http://example.com/wow), the result is http://example.com/3, which is correct: The 2 replaces the wow, and the 3 replaces the 2. This is how relative URLs work. If you want to stack them and get http://example.com/wow/2/3, you need / at the end of wow and 2: import … Read more
Taken from here The contract between equals() and hashCode() is: 1) If two objects are equal, then they must have the same hash code. 2) If two objects have the same hash code, they may or may not be equal. Therefore: any class that defines equals() differently than this == other must have its own … Read more
Answer link : NoClassDefFoundError below SDK 21 I resolved the issue by adding this to my Application Class. @Override protected void attachBaseContext(Context base) { super.attachBaseContext(base); MultiDex.install(this); } If you don’t have/use Application class, you can put this: android:name=”android.support.multidex.MultiDexApplication” Into your tag on AndroidManifest.xml If you already have implemented an Application class Also obviously, you need … Read more
Thread constructor is like Thread t = new Thread(Runnable runn) and not (new Runnable(){}). When we do something as shown below Thread t = new Thread(new Runnable() { @Override public void run() { // TODO Auto-generated method stub } }); It’s basically asking us to implements run method as defined in Runnable inteface. Alternatively we … Read more
And please no win32, mfc or qt. I fear these are too complex for me for now, unless you really recommend it. Doing graphics without some kind of framework is actually a lot harder than using any one of the frameworks that you have listed. Orders of magnitude harder … if you could measure hardness … Read more
