printStackTrace in JSP

printStackTrace is a method of the Throwable class. By using this method we can get more information about the error process if we print a stack trace from the exception.

The code of the program is given below:

<HTML>
    <HEAD>
        <TITLE>Trace a Stack to the Server Console</TITLE>
    </HEAD>

    <BODY>
	<FONT SIZE="5" COLOR="#660033" align="center">
        Trace a Stack to the Server Console</FONT>
        <%
		try{
               int a[] =new int[6];

		for(int i = 0; i<7; i++){

		 a[i]=i;
		}

            }
            catch (Exception e){
                e.printStackTrace();
            }
        %>
    </BODY>
</HTML>

Output of the Program:

java.lang.ArrayIndexOutOfBoundsException: 6
