Converting Stack Trace to String

Obtaining the details of an exception's stack trace as a string representation can be useful for logging or displaying stack trace information. Here's an efficient method to convert the result of Throwable.getStackTrace() into a string:

Method:

Use Throwable.printStackTrace(PrintWriter pw) to send the stack trace to a PrintWriter. The PrintWriter can then be used to retrieve the stack trace as a string.

Example:

import java.io.StringWriter;
import java.io.PrintWriter;

// ...

StringWriter sw = new StringWriter();
PrintWriter pw = new PrintWriter(sw);
e.printStackTrace(pw);
String sStackTrace = sw.toString(); // stack trace as a string
System.out.println(sStackTrace);
