I have a method that is called when my program recieves messages from a server.
It is given a string(the message)

I am attempting to seperate the string with "+" characters in order to transmit more efficient messages.

Scanner scan = new Scanner(stringVar);
scan.useDelimiter(" + ")

I then proceed to print out each seperated string on a new line.

if(scan.hasNext())
{
    do
    {
        System.out.println(scan.Next());
    }
    while(scan.hasNext())
}
else
{
    scan.close();
}

For some reason, either of these processes is broken as the whole input string is printed in one line!

What i want:
Line1
Line2
Line3
Line4

What happens:
Line1 + Line2 + Line3 + Line4


Is there any thing that i am doing wrong?
Also if there is a more efficient way of doing this...

Can you show us the whole example?

Sure

import java.util.Scanner;

public class incomingFromServerHandler 
{
	public static void actionPerformed(String string) 
	{
		Scanner scan = new Scanner(string);
		scan.useDelimiter(" + ");
		
		if(scan.hasNext())
		{
			do
			{
				System.out.println(scan.next());
			}
			while(scan.hasNext());
		}
		else
		{
			scan.close();
		}
	}
}

Why not simply using:
string.split("\\+")
or string.split(" \\+ ") if you want the spaces
on the received line ?

Don't forget the \\ because + is a meta character in regex

Would this split is every time a "+" appears?
Also how would i then access the different sections of the string?

Thanks though

String[] token = string.split("\\+");
for(int i = 0; i < token.length; ++i) {
   .. access here each token[i] one after the other
