Assuming you want to return an array with two values (namely the min and the max), you can build that in one line like return new int[] { min, max }; I would also prefer Integer.min(int, int) and Integer.max(int, int) for finding those values. Like, static int[] records(int[] score) { int max = score[0], min … Read more
As you say Sqlite is about storing in the device. .

According to the JLS, subexpressions are evaluated from left to right. That’s why the first term is evaluated to 5, the second one is evaluated to 6 and third one is evaluated after the second one so it gives 6. That’s why the sum is 17. 8 solved How to evaluate this expression [duplicate]
You have to change the name of your class because the class Arrays is already part of the java API and that would create confusion import java.util.Arrays; public class OtherNameThanArrays { public static void main(String[] args) { int[] numbers = new int[5]; numbers[0] = 31; numbers[1] = 88; numbers[2] = 11; numbers[3] = 73; numbers[4] … Read more
Not sure, if this is what you want, but you would need to update your total within the loop to update the value in the Total Compensation column. Let’s start with the little things you should change first. The naming convention in Java is camel-case. You should change that accordingly. For example, rather than getsalesDouble … Read more
Change final Spinner spinner = new Spinner(this); to final Spinner spinner = (Spinner) findViewById( R.id.spinner1 ); Since final variables are tied to the first instance you give them, and you really don’t need to make a Spinner only to find the one you’re looking for. Since you then want to use the Spinner inside an … Read more
you are actually looking for _GET[‘message3’]variable.. do something like that $message = _GET[‘message3’] ; if(isset($message){ $sql = insert your $message variable in database here run the query } etc.. and you are done I assume that you are learning over your localhost and you got the file Sent.jsp solved How do I store the data … Read more
I think your problem is in this method: synchronized void PrintMsg(String msg) { System.out.println(msg); try { wait(); } catch (InterruptedException e) { System.out.println(“Exception”); } System.out.println(msg); notify(); } The thread that call it are going to call wait() which causes them to wait indefinitely for someone to call notify(). But there are no other calls to … Read more
You can use a SimpleDateFormat like so: SimpleDateFormat format = new SimpleDateFormat(“yyyyMMdd”); Date date = format.parse(“20150119″); Calendar calendar = GregorianCalendar.getInstance(); calendar.setTime(date); solved Simple way to convert “yyyyMMdd”-formatted string into a GregorianCalendar object
Try this. package lesson5; import java.util.Scanner; public class task3 { public static void main(String[] args) { Scanner sc = new Scanner(System.in); int [] masarray = new int [10]; int a,b,c,d,f,g,j,m,n,l; int flag_even =0; int min_even = 0; float sum_even=0; float sum_odd=0; int total_even=0; int total_odd=0; System.out.println(“input first number of array”); a=sc.nextInt(); masarray [0]= a; System.out.println(“input … Read more
Since you are new to java I recommend reading up on some tutorials. As it seems you are not familiar with java in general. An example, which I have not used myself, is http://www.javaworld.com/blog/java-101. It may be worth your time to read this over. As for your actual question, you would create a variable in … Read more
It’s just 106 “public final static int int1 = int1value” in the first class. No List or Arrays. How lame! Unfortunately there is no neat way to sum the values of a large number of statics. You could do it using reflection (see @BalusC’s answer), or simply by writing a method evaluates hard-wired expressions like: … Read more
