How can I print something in the same line as the user input?

Question

I wrote this code:

import java.util.Scanner;
public static void main (String[] args){
   Scanner scan = new Scanner (System.in);
   String inp;
   int m;
   System.out.println ("Please enter some characters.");
   inp = scan.nextLine();
   m = inp.length();
   System.out.println(" = " + m);
}

If I run that, I get something like this:

Please enter some characters.
12345
 = 5

But how can I get the = 5 to be printed on the same line as the characters entered by the user, like below?

Please enter some characters.
12345 = 5

As an explanation to Gumbo's comment, this wouldn't be possible on the command line (e.g. using a `Scanner` and `System.in`) because Java doesn't even see the input until the user hits `ENTER`, which forces the `= 7` to be on another line. — Justin, Sep 16 '15 at 15:50
You could always remember the input, clean the console and print input + output together, couldn't you? — Vic, Sep 16 '15 at 15:55

There is no function in standard Java that allows you to easily do this.

You will need to interact with the terminal using ANSI escape codes. This is not supported by all terminals.

You could also use a library that will do this for you, some examples in random order:

I can't help you if you don't tell me what part you don't understand. – emilianogc Sep 17 '15 at 12:08
I don't get that "You need to interact with the terminal you are using." – Jos Sep 17 '15 at 17:01

just write like this:

System.out.print(" = " + m);

println prints to a new line. hope it works

 System.out.print("Please enter some characters.");
 inp = scan.nextLine();
 m = inp.length();
 System.out.println(" = " + m);

When you print the question, remove the ln part (System.out.print("Please enter....)) This will allow your input to be on the same line as the prompt. Then you can print System.out.println( inp + " = " + m); However you can't type something after the input as far as i know but you can echo it.

How can I print something in the same line as the user input?
