Java Utililty Methods Throwable to String

final StringWriter strWriter = new StringWriter();
if (exception.getCause() == null) {
    exception.printStackTrace(new PrintWriter(strWriter, true));
} else {
    exception.getCause().printStackTrace(new PrintWriter(strWriter, true));
strWriter.flush();
return strWriter.toString();
...

Returns the stack trace of the given exception as a string.

StringBuffer result = new StringBuffer();
try {
    StringWriter writeBuffer = new StringWriter();
    PrintWriter printBuffer = new PrintWriter(writeBuffer);
    t.printStackTrace(printBuffer);
    printBuffer.flush();
    printBuffer.close();
    result.append(writeBuffer.toString());
...

final ByteArrayOutputStream bas = new ByteArrayOutputStream();
final PrintWriter pw = new PrintWriter(bas);
t.printStackTrace(pw);
pw.close();
return bas.toString();

try {
    final ByteArrayOutputStream out = new ByteArrayOutputStream();
    t.printStackTrace(new PrintStream(out, false, "UTF-8"));
    return new String(out.toByteArray(), "UTF-8");
} catch (final IOException exc) {
    return null;

final StringWriter sw = new StringWriter();
t.printStackTrace(new PrintWriter(sw));
return sw.toString();

Gets the stack trace from a Throwable as a String.

The result of this method vary by JDK version as this method uses Throwable#printStackTrace(PrintWriter) .

final StringWriter sw = new StringWriter();
final PrintWriter pw = new PrintWriter(sw, true);
throwable.printStackTrace(pw);
return sw.getBuffer().toString();

final Writer result = new StringWriter();
final PrintWriter printWriter = new PrintWriter(result);
aThrowable.printStackTrace(printWriter);
return result.toString();

final Writer result = new StringWriter();
final PrintWriter printWriter = new PrintWriter(result);
aThrowable.printStackTrace(printWriter);
return result.toString();

StringWriter out = new StringWriter();
PrintWriter w = new PrintWriter(out);
e.printStackTrace(w);
w.flush();
return out.toString();

String stackTrace = "";
Writer writer = null;
PrintWriter printWriter = null;
try {
    writer = new StringWriter();
    printWriter = new PrintWriter(writer);
    e.printStackTrace(printWriter);
    stackTrace = writer.toString();
