Different ways to print exception messages in Java
Following are the different ways to handle exception messages in Java.
Using printStackTrace() method − It print the name of the exception, description and complete stack trace including the line where exception occurred.
catch(Exception e) { e.printStackTrace(); }
Using toString() method − It prints the name and description of the exception.
catch(Exception e) { System.out.println(e.toString()); }
Using getMessage() method − Mostly used. It prints the description of the exception.
catch(Exception e) { System.out.println(e.getMessage()); }
Example
import java.io.Serializable; public class Tester implements Serializable, Cloneable { public static void main(String args[]) { try { int a = 0; int b = 10; int result = b/a; System.out.println(result); } catch(Exception e) { System.out.println("toString(): " + e.toString()); System.out.println("getMessage(): " + e.getMessage()); System.out.println("StackTrace: "); e.printStackTrace(); } } }
Output
toString(): java.lang.ArithmeticException: / by zero getMessage(): / by zero StackTrace: java.lang.ArithmeticException: / by zero at Tester.main(Tester.java:8)
