There are two ways to find the details of the exception, one is the printStackTrace() method and another is the getMessage() method.
printStackTrace() method
- This is the method which is defined in java.lang.Throwable class and it is inherited into java.lang.Error class and java.lang.Exception class.
- This method will display the name of the exception and nature of the message and line number where an exception has occurred.
Example
public class PrintStackTraceMethod { public static void main(String[] args) { try { int a[]= new int[5]; a[5]=20; } catch (Exception e) { e.printStackTrace(); } } }
Output
java.lang.ArrayIndexOutOfBoundsException: 5 at PrintStackTraceMethod.main(PrintStackTraceMethod.java:5)
getMessage() method
- This is a method which is defined in java.lang.Throwable class and it is inherited into java.lang.Error and java.lang.Exception classes.
- This method will display the only exception message.
Example
public class GetMessageMethod { public static void main(String[] args) { try { int x=1/0; } catch (Exception e) { System.out.println(e.getMessage()); } } }
Output
/ by zero
