I have just started to do programming ...I am trying to sort an array in ascending order.. but not getting desired result , please point where i am doing wrong..
public static void main(String[] args) {
int count, temp;
// User inputs the array size
Scanner scan = new Scanner(System.in);
System.out.print("Enter number of elements you want in the array: ");
count = scan.nextInt();
int num[] = new int[count];
System.out.println("Enter array elements:");
for (int i = 0; i < count; i++) {
num[i] = scan.nextInt();
}
scan.close();
{
int i = 0;
while (i <= count) {
for (int j = i + 1; j < count; j++) {
if (num[i] > num[j]) {
temp = num[i];
num[i] = num[j];
num[j] = temp;
i++;
}
}
}
}
System.out.print("Array Elements in Ascending Order: ");
for (int i = 0; i < count - 1; i++) {
System.out.print(num[i] + ", ");
}
System.out.print(num[count - 1]);
}
you should increment the i outside the for loop or you can get rid of the while loop and use for loop too, you can find the code below :
import java.util.Scanner;
public class Ascending _Order
{
public static void main(String[] args)
{
int n, temp;
Scanner s = new Scanner(System.in);
System.out.print("Enter no. of elements you want in array:");
n = s.nextInt();
int a[] = new int[n];
System.out.println("Enter all the elements:");
for (int i = 0; i < n; i++)
{
a[i] = s.nextInt();
}
for (int i = 0; i < n; i++)
{
for (int j = i + 1; j < n; j++)
{
if (a[i] > a[j])
{
temp = a[i];
a[i] = a[j];
a[j] = temp;
}
}
}
System.out.print("Ascending Order:");
for (int i = 0; i < n - 1; i++)
{
System.out.print(a[i] + ",");
}
System.out.print(a[n - 1]);
}
}
Output:
Enter no.of elements you want in array:5
Enter all the elements: 4 3 2 6 1
Ascending Order:1,2,3,4,6
or you can use the method sort :
import java.util.Scanner;
import java.util.Arrays;
public class Ascending_Order {
public static void main(String[] args) {
int n, temp;
Scanner s = new Scanner(System.in);
System.out.print("Enter no. of elements you want in array:");
n = s.nextInt();
int a[] = new int[n];
System.out.println("Enter all the elements:");
for (int i = 0; i < n; i++) {
a[i] = s.nextInt();
}
Arrays.sort(a);
System.out.print("Ascending Order:");
for (int i = 0; i < n - 1; i++) {
System.out.print(a[i] + ",");
}
System.out.print(a[n - 1]);
}
}
Output:
Enter no.of elements you want in array:5
Enter all the elements: 4 3 2 6 1
Ascending Order:1,2,3,4,6
