How ever i could reach with output as

word description

Stem/Suffix: descriptio/n
Stem/Suffix: descripti/no
Stem/Suffix: descript/noi
Stem/Suffix: descrip/noit ................

suffix should come in reverse of what its showing.. with below code

import java.util.Collections;
import java.util.Scanner;
public class MorphemeA
{
public static void main(String args[])
{
Scanner sh = new Scanner(System.in);
System.out.println("Enter a word");
String str = sh.next();
char[] ch = str.toCharArray();
int y = str.length();
for (int m = y ; m <= y; m--)
{
String pl1 = new String(ch,0,m);
if(pl1.length()>=2)
{
int l=8;
char[] dh = new char[l];
int c=y-1;
int g = l-1;
char[] eh = new char[l];
int h = 0;
for (int j=c; j<=y; j--)
{
if(m>2)
{
eh[h] = ch[j];
// Collections.reverse(dh);

            String pl = new String(ch,0,--m);

            //Collections.reverse(eh);

            String mpm  = new String(eh,0,8);


            System.out.println("Stem/Suffix:"+pl +"/"+mpm);
            h++;
 }

    }

}
}
}
}
