Write a Java Program to perform Selection Sort using static function

Here is source code of the Java Program to implement Selection Sort. The Java program is successfully compiled and run on a Windows system(NetBeans). The program output is also shown below.

SOURCE CODE : :

import java.util.Scanner;

public class SelectionSort {
    
    //------------------Enter data Function--------------------------------
    
    static int [] enter_data()
    {
        int i,n;
        Scanner sc = new Scanner(System.in);
        System.out.print("Enter no. of elements u want to sort :");
        n=sc.nextInt();
        int a[]=new int[n];
        System.out.println("Enter elements--->");
        
        for(i=0;i<n;i++)
        {
            System.out.print((i+1)+" Element : ");
            a[i]=sc.nextInt();
        }
        return a;
    }

    //--------------------Selection Sort Function-----------------------------
    
    static int [] selectionsort(int a[])
    {
        int i,j,temp,len,min;
        len=a.length;
        
        for(i=0;i<len-1;i++)
        {
            min=a[i];
            for(j=i+1;j<len;j++)
            { 
                if(min>a[j])
                {
                    temp=a[j];
                    a[j]=min;
                    min=temp;
                }
                a[i]=min;
            }
        }
        
        return a;
    }
    
    //-----------------Print array---------------------------------------
    
    static void printarray(int arr[])
    {
        int i,len;
        len=arr.length;
         System.out.println("\nAfter Sorting Elements are : ");
         for(i=0;i<len;i++)
        {
            System.out.println((i+1)+" Element : "+arr[i]);
        }
    }
    
    //-----------------------Main Function-------------------------------
    
    public static void main(String[] args) {
        
        int a[],b[];
        
        a=enter_data();
        
        b=selectionsort(a);
        
        printarray(a);
        
    }
    
}

OUTPUT : :

Enter no. of elements u want to sort :5
Enter elements--->
1 Element : 3
2 Element : 1
3 Element : 8
4 Element : 5
5 Element : 7

After Sorting Elements are : 
1 Element : 1
2 Element : 3
3 Element : 5
4 Element : 7
5 Element : 8
