Java Program to Convert a Stack Trace to a String
The Java.io.StringWriter class is a character stream that collects its output in a string buffer, which can then be used to construct a string. Closing a StringWriter has no effect.
The Java.io.PrintWriter class prints formatted representations of objects to a text-output stream.
Using these two classes you can convert a Stack Trace to a String.
Example
import java.io.PrintWriter;
import java.io.StringWriter;
public class StackTraceToString {
public static void main(String args[]) {
try {
int a[] = new int[2];
System.out.println("Access element three :" + a[3]);
} catch (ArrayIndexOutOfBoundsException e) {
StringWriter writer = new StringWriter();
e.printStackTrace(new PrintWriter(writer));
String myString = writer.toString();
System.out.println("Stack trace message ::"+myString);
}
}
}Output
Stack trace message ::java.lang.ArrayIndexOutOfBoundsException: 3 at lastRound.StackTraceToString.main(StackTraceToString.java:10)
