Hi Friend,

Try the following code:

import java.util.*;
class  StringExample3
{
    public static void main(String[] args) 
    {
        Scanner input=new Scanner(System.in);
        System.out.print("Enter word: ");
        String st=input.next();
        for(int i=0;i<=st.length();i++){
            int j=i+1;
            System.out.println(st.substring(0,i));
        }
    }
}

Thanks
