How to Rethrow an Exception in Your Code

Use the
 fillInStackTrace()
method to rethrow a Throwable type of exceptional condition in your code. This is useful if you want to rethrow a exception occurred while using a method or creating a Object but want to avoid the stack trace from these calls.

The intention is to show the stack trace starting from this method or error condition. This a similar to creating a new Object of type Throwable and throwing it as the exception; this happens when the call to

 fillInstackTrace
method is made; it returns a new Object of type Throwable filled with the execution stack trace. Example code:
 
import java.io.IOException;

public class testExceptions
  {

Example of fillInStackTrace
 	  
  	void method1() throws Throwable
  	  {
  	     throw new Throwable("Throwable Exception in method1"); 	
  	  } 
  	
  	void method2() throws Throwable
  	  {
throw new IOException("Exception in method2");
 	try
		 {
		    method1();			
		 }
		catch(Throwable th)
		 {
throw th;
  	throw th.fillInStackTrace();
similar to throw new Throwable();
 		 }

  	  } 
Example of fillInStackTrace
 	  
	public static void main(String args[]) throws Throwable
	 {
		new testExceptions().method2();			
	 }  
  }
