Thread: Array -Sorting

Write a program to sort a given array
(Passing Array to a Method in Java- get an array from user input
Returning Array from the Method-sort and then return the sorted array)

import java.util.Scanner; 
public class SortClass {
   public int Ascending(int [] myarray) {
       int n=0,temp;
       int a[] = new int[n];  
 
       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.println("Array elements in descending order:");  
for ( i=n; i < n - 1; i--)   
    {  
        System.out.println(a[i]);  
    }  
return (a[n - 1]);  
}  
 
 
   }
 
 
public static void main(String[] args)   
{  
int n, temp;  
Scanner s = new Scanner(System.in); 
SortClass SC=new SortClass();
System.out.print("Enter the number of elements: ");  
n = s.nextInt();  
int a[] = new int[n];  
System.out.println("Enter the elements of the array: ");  
for (int i = 0; i < n; i++)   
{  
a[i] = s.nextInt();  
}  
for (int i = 0; i < n; i++)   
{  
           SC.Ascending(a);
}  
System.out.println("Array elements in Ascending order:");  
System.out.println("Array elements in Ascending order:"+SC.Ascending(a));  
 
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.println("Array elements in descending order:");  
for (int i = 0; i < n - 1; i++)   
{  
System.out.println(a[i]);  
}  
System.out.print(a[n - 1]);  
}  
 
}

Thanks in advance.

What have you tried? Post your code if you need help with it.
This site does not provide full source code.

Be sure to wrap all posted code with code tags:

to get highlighting and preserve formatting.

The code is very poorly formatted making it hard to read and understand. Please fix the code's formatting.

missing return statement

There is a missing return statement in the Ascending method (note java standards suggest method names should start with lowercase letter).
There needs to be a return statement at the end of all execution paths. The return statement is inside of a loop which might not be executed. Make sure there is a return statement outside of the loop.
The code's poor formatting makes it hard to see.
