Actually, you could probably use


public static void main (String[] main) {

Initialize your class
Write a loop to get your numbers
send to method in that classs

}

So, your answer is. You don't have to use two classes. In fact, just one for your selection sort and have the user input numbers in the public static void part.

hi..
I am writing the code for selection sort, you'll need to pass the numbers for sorting as command line arguments that is along with the command you use to run the java program

e.g., java Selection 12,45,1,76,50

the code is as follows:

class Selection
{
public static void main(String arg[])
{
int x[]; //declaring an empty array,initialized later
int i;

//checking if arguments have been given or not at the command line
if(arg.length==0)
System.out.println("No Arguments Specified...\n");//prints msg if no args specified

else
{
x=new int[arg.lenght]; //initializing the array with the no. of args specified.

try //trapping any errors that might occur
{
for(i=0;i<x.length;i++) //loop for putting the values into the array
x[i]=Integer.parseInt(arg[i]);

selectionSort(x); //calling the method for sorting,defined later in the class

//printing the sorted list
System.out.println("Sorted List:-");

for(i=0;i<x.length;i++)
System.out.println(x[i]);
}
catch(NumberFormatException E) //traps the error if specified arg is not a number
{
System.out.println("Given argument is not a number...\n");
}
}
}

static void selectionSort(int x[]) //method for sorting the list,made static for using in main
{
int i,j;
int pos=0; //variable to fix a position in array
int min=0; //variable to fix a number as minimum.

for(i=0;i<x.length-1;i++)
{
min=x[i+1]; //setting the minimum number
pos=i+1; //fixing the position to the index of that number

for(j=i+1;j<x.length;j++)
{
if(min>x[j]) //if number at x[j] is graeter than minimum then
{
min=x[j]; //put x[j] in min
pos=j; //and change position to index number of j
}
}

if(x[pos]<x[i]) //if number at x[pos] is less than number at x[i] then swap the values
{
x[pos]=x[pos]+x[i];
x[i]=x[pos]-x[i];
x[pos]=x[pos]-x[i];
}
}
}
}


hope this code will help you..
we do not need to create to separate classes for sorting a list here.

NICE WORK!!! You did his homework for him!!!!

hii
try to use two function rather tha two class

import java.util.*;
public class DS2
{
public static void main(String[] args)
{
Scanner k=new Scanner(System.in);
int[] ds=new int[10];
for (int z=0;z<10;z++)
{
Random R=new Random();
int x=R.nextInt(999)+1;
ds[z]=x;
}
System.out.println("Numbers Before Sort:\n"+ds[1]+","+ds[2]+","+ds[3]+","+ds[4]+","+ds[5]+","+ds[6]+","+ds[7]+","+ds[8]+","+ds[9]+"\n");
Arrays.sort(ds);
System.out.print("Numbers After Sort:\n"+ds[1]+","+ds[2]+","+ds[3]+","+ds[4]+","+ds[5]+","+ds[6]+","+ds[7]+","+ds[8]+","+ds[9]);
}
}

hai..pwedi nyo b akong bgyan ng isang code about selection sort....thanks

Start a new thread and write proper english

can you gave us a running program about selection sort that the user will input something from the keyboard...thank you...

NO.

Start a new thread. There are plenty of examples on how to read input with the Scanner class. Start a new thread with some code.
