How do I get an exception stack trace message?
Category: java.io, viewed: 1400 time(s).
In this example we use the StringWriter and PrintWriter class to convert stack trace exception message to a string.
package org.kodejava.example.lang;
import java.io.StringWriter;
import java.io.PrintWriter;
public class StackTraceToString {
public static void main(String[] args) {
try {
int a = 10 / 0;
} catch (Exception e) {
//
// Create a StringWriter and a PrintWriter both of these object
// will be used to convert the data in the stack trace to a string.
//
StringWriter sw = new StringWriter();
PrintWriter pw = new PrintWriter(sw);
//
// Instead of writting the stack trace in the console we write it
// to the PrintWriter, to get the stack trace message we then call
// the toString() method of StringWriter.
//
e.printStackTrace(pw);
System.out.println("Error = " + sw.toString());
}
}
}
