This was found using google in two minutes. So are you saying you can't even use google? :rolleyes:

I'm half tempted to just provided a bubble sort and let him submit that to his teacher not knowing any better..

Muuuwhahhahhahahah. That would have been hilarious.

this is one is more simple and better!!

import java.io.*;
class insertion
{
public static void main() throws IOException
{
InputStreamReader isr = new InputStreamReader(System.in);
BufferedReader br= new BufferedReader(isr);
System.out.println("Please Enter the number of values");
int a=Integer.parseInt(br.readLine());
int age[]=new int[a];
int minelem=0, temp;
System.out.println("Enter the VALUES");
for(int x=0;x<a;x++)
{
age[x]=Integer.parseInt(br.readLine());
}
System.out.println("The number in ascending order are: ");
    int min;
   for(int x=0;x<a-1;x++)
   {
       min=age[x];
       for(int y=x+1;y<a;y++)
       {
           if(min>age[y])
           {
               min=age[y];
               minelem=y;
                            
            }
        }
        System.out.println("Minimum Value: " + min);
        temp=age[minelem];
        age[minelem] = age[x];
        age[x]=temp;
    }
    for(int w=0;w<a;w++)
    {
        System.out.println(age[w]);

hey dude!!
i know no one cares about this thread
but people who search on google about insertion sorting
it might be helpful to them!!
its for them not for this thread!!
GOT IT

hey "dude",

JamesCherrill is right. If you have found thé way to do this task, no one's stopping you from creating your own thread, and put a title like:

THÉ ULTIMATE WAY TO ... insertion sorting, or whatever, and posting your code, this way, every one googeling the topic will find it too, and you don't have to make us read through all the dates, just to figure out which one might be a current question.
also, you're writing a lot of code, while even manually sorting the array would even take less code, not to mention the sort functions that are standard available in the java libraries. I have no doubt that you want to help other developers, but then why not by answering questions that are currently being asked?

My personal opinion for anyone possibly reading this: Above presented code may pass you for your assignment, but code quality and standards are very low so it is not best example to use.
