PORT.LNSP

Do not hardcode `\n' or `\r' as a line separator

Description

This rule flags code where `\n' or `\r' is hardcoded as a line separator.

Different systems use different characters or sequences of characters as line separators. Therefore, hardcoding `\n', `\r', or `\r\n' damages Java code's portability.

Example

 package PORT;
 
 public class LNSP {
     public printHeader (String name, String id) {
         System.out.println("HEADER \n" +"Name: name \n" +"ID: id
\n");
     }
 }

Repair

Use the `println()' method of PrintStream or PrintWriter; this automatically terminates a line with the line separator appropriate for the platform. Or, use the value of System.getProperty(`line.separator')

 package PORT;
 
 public class LNSP {
     public printHeader (String name, String id) {
         System.out.println("HEADER ");
         System.out.println("Name:  " +name);
         System.out.println("ID:  " +id);
     }
 }
