Code:

public class Main
{
    public static String removerec(String s)
    {
        /*Create empty string*/
        String res="";
        int n=s.length();
        for(int i=1;i<n;i++)
        {
            /*If a chacater not equals to it's previous character*/
            if(s.charAt(i-1)!=s.charAt(i))
            {
                /*append previous character to cretaed string*/
                res=res+s.charAt(i-1);
            }
        }
        /*append last character of string*/
        res=res+s.charAt(n-1);
        return res;
    }
        public static void main(String[] args) 
        {
                System.out.println(removerec("apple"));
                System.out.println(removerec("banana"));
                System.out.println(removerec("baaannannnnaa"));
        }
