Does anyone know how to find a median of an array? How do we sort it first?

//created by akshgods 
import java.util.*;
class median
{
public static void main(String args[])
{
Scanner sc=new Scanner(System.in);
int size=5,temp=0,mid=0,pnt1=0,pnt2=0;
System.out.println("Enter the size of array");
size=sc.nextInt();//taking size for array
int a[]=new int[size];
//taking values in array
System.out.println("Enter the values");
for(int i=0;i<size;i++)
{
a[i]=sc.nextInt();
}
//sorting array with bubbule sort in ascending order
for(int i=0;i<size-1;i++)
{
for(int j=0;j<size-i-1;j++)
{
if(a[j]>a[j+1])
{
temp=a[j];
a[j]=a[j+1];
a[j+1]=temp;
}
}
}
//printing values in ascending order
System.out.println("values in ascending order");
for(int i=0;i<size;i++)
{
System.out.print(" "+a[i]);
}
//finding medean logic
if(size%2==0)
{
pnt1=size/2;
pnt2=pnt1-1;
mid=(a[pnt1]+a[pnt2])/2;
System.out.println("\nmidean is= "+mid);
}
else
{
pnt1=(size+1)/2;
pnt1--;
mid=a[pnt1];
System.out.println("midean is= "+mid);
}
}
}

Why is it giving me a zero.
double percent = 0;
if(condition) {
percent = scrollpane.getHeight() / origIcon.getImage().getHeight(scrollpane);
System.out.print(scrollpane.getHeight() + " / " + origIcon.getImage().getHeight(scrollpane));
System.out.println(" = " + percent);
} else {
}
This returns 309 / 1668 = 0.0 value should be 0.1852..
I know this is basic but I DON'T KNOW. sorry, too tired I guess but I need this to figure out
Thanks

Because that's what scrollpane.getHeight() / origIcon.getImage().getHeight(scrollpane) returns, due to integer datatypes.
I don't know Java, but I expect you could do something like:
percent = scrollpane.getHeight();
percent = percent / origIcon.getImage().getHeight(scrollpane);

well that gives me an idea.. casting should do the trick
Thanks

Hello. Can anybody help me create a program that lets user input positive integers and exits if a negative integer is input? the program that outputs max,min, and average of the integers. i have tried to do it since a week and i am stuck in an infinite while loop

If you show the code* that is failing then people will try to help you.
*Please ensure your code is formatted between <pre lang="java"></pre> tags so it is readable.

He did. In the Quick Answers post that was then closed because it was flagged as a duplicate.

public static void main(String[] args) {
Scanner in=new Scanner(System.in);
System.out.println("Enter a positive integer");
int userinput=in.nextInt();
int maxer=0;
int miner=0;
int sum=0;
int counter=1;
if(maxer<userinput){
maxer=userinput;
counter++;
sum=sum+userinput;
}
if(miner>userinput){
miner=userinput;
counter++;
sum=sum+userinput;
}
int avg= sum/counter;
System.out.println("Your maximum integer is "+maxer);
System.out.println("Your minimum integer is "+miner);
System.out.println("Your average is "+avg);
}
}
This is my code here

One of the problems with this code is there's no loop present; so the summing and min/max computation (which may not be correct anyway) will only execute once. You may want to use a construct like this:
do {
get user input;
if (input is not negative) {
compute new min/max;
compute sum;
}
while (input is not negative);
display results;

but how do i write input is not negative in code?
i am in new in java so i am still not aware of the syntax.
|

can u plz tell how many integers do u want to take in program? for max,min and average?

i wanna make a class in JComponent library in the following way :
class HelloComponent extends JComponent {
but the "JComponent cannot be resolved to a type" message would show up . any idea ?
|
|
|
|
|
You need to show a bit more of your code and the actual line that the message occurs on. Did you import the JComponent definition?
|
|
|
|
|
Eclipse can't find the type JComponent
What kind of JComponent is it? What kind of GUI are you creating?
That name is used way to.
regards Torsten
I never finish anyth...

I have a task at hand for designing persistence layer for an application that should be generic. It is kind of application that will provide infrastructure for doing activities.I need help regarding how should my approach be towards it . Persistence can be through either XML or through database or through configuration files. Please provide me points to keep in mind as well as any special design considerations I should be aware of.
