Program for character stuffing

import java.util.*;
class Char
{
    public static void main(String r[])
    {   
        Scanner sc=new Scanner(System.in);
        System.out.println("Enter number of characters: ");
        int n=sc.nextInt();
        String in[]=new String[n];
        for(int i=0;i<n;i++)
        {
            in[i]=sc.next();
        }
        for(int i= 0;i<n;i++)
        {
            if(in[i].equals("dle"))
            {
                in[i]="dle dle";
            }
        }
        System.out.println("Transmitted message is: ");
        System.out.print(" dle stx ");

            System.out.print(in[i]+" ");
        }
        System.out.println(" dle etx ");
    }
}


Example:
Sample output:
Enter number of characters:
5
a b dle dle d e
Transmitted message is:
dle stxa b dle dle dle dle d dle etx

WAP TO REVERSE A GIVEN SENTENSE

JAVA Programs

import java.util.*;
public class ReverseSentense
{
public static void main(String args[])
{
Scanner sc=new Scanner(System.in);
String s;
System.out.println("Enter a sentense:");
s=sc.nextLine();
String temp[];
temp=s.split(" ");
for(int i=temp.length-1;i>=0;i--)
System.out.print(temp[i]+" ");
}
}

output:-
let the input be:
hello my name is rishabh
then the output will be:
rishabh is name my hello
