Java – StackTrace to String conversion

There are times when we want to convert the occurred exception to String. In the following program we are converting the stacktrace to String by using Throwable.printStackTrace(PrintWriter pw).

Example: Converting Exception StackTrace to String

package com.beginnersbook.string;

public class StacktraceToString {
    public static void main(String args[]){
            int i =5/0;
        }catch(ArithmeticException e){
            /* This block of code would convert the
             * stacktrace to string by using
             * Throwable.printStackTrace(PrintWriter pw)
             * which sends the stacktrace to the writer
             * that we can convert to string using tostring()
            StringWriter sw = new StringWriter();
            PrintWriter pw = new PrintWriter(sw);
            String stacktraceString = sw.toString();
            System.out.println("String is: "+stacktraceString);

String is: java.lang.ArithmeticException: / by zero
at com.beginnersbook.string.StacktraceToString.main(
