Java Newline and Carriage Return Characters

A newline is represented by \n and a carriage return by \r. UNIX only seems to recognize the newline:

 

UNIX > cat prog24.java

public class prog24

{

public static void main (String args[])

  {

  System.out.println("Newline->\n");

  System.out.println("Carriage return->\r");

  }

}

UNIX > javac prog24.java

UNIX > java prog24

Newline->

 

Carriage return->

UNIX >

 

If you copy the program to a Windows environment and run it in a command prompt, both characters are recognized:

 

C:\Users\J0294094\Java>java prog24

Newline->

 

Carriage return->

 

C:\Users\J0294094\Java>

Compile Once - Run Anywhere

In the previous example, I compiled and ran prog11 on a Solaris machine. Java is designed to be platform independent or portable. To show that it could be run on a different platform, I copied the prog11.class file to a Windows 7 machine in binary mode. Then I ran it there as follows:

 

C:\Java>dir

Volume in drive C is System

Volume Serial Number is B068-444A

 

Directory of C:\Java

 

04/29/2013  05:37 PM    <DIR>          .

04/29/2013  05:37 PM    <DIR>          ..

04/29/2013  05:36 PM               717 prog11.class

               1 File(s)            717 bytes

               2 Dir(s)  204,152,512,512 bytes free

 

C:\Java>java prog11

a = 100

b = 100

 

C:\Java>
