Java program to find first 5 largest numbers in a list

import java.util.*;
class big
{
public static void  main(String args[])
{
int i;
System.out.println("Enter the size of the list (It should be greater than five) ");
Scanner sc=new Scanner(System.in);
int n=Integer.parseInt(sc.nextLine());
int a[]=new int[n];
if(n>5)
{
System.out.println("Enter the elements ");
for(i=0;i<n;i++)
{
a[i]=Integer.parseInt(sc.nextLine());
}
System.out.println("Entered elements are ");
for(i=0;i<n;i++)
{
System.out.println(a[i]);
}

//sorting the elements
for(i=0;i<n;i++)
{
for(int j=i+1;j<n;j++)
{
if(a[i]>a[j])

int temp;
temp=a[i];
a[i]=a[j];

}
}
}
System.out.println("Sorted list");
for(i=0;i<n;i++)

}

}
else
