IllegalArgument

IllegalArgument Exception is thrown when an illegal argument is sent to the method.

Example

import java.io.*;
public class GetStackTraceAsString{

  public static String getStackTrace(Throwable throwable) {
  Writer writer = new StringWriter();
  PrintWriter printWriter = new PrintWriter(writer);
  throwable.printStackTrace(printWriter);
  return writer.toString();
  }
  public static void main (String[]args){
  final Throwable throwable = new IllegalArgumentException("Hello");
  System.out.println( getStackTrace(throwable) );
 }
}
