import java.io.*; public class RedirectingErrors { public static void main(String[] args) { try { // Redirecting errors to a file System.setErr(new PrintStream(new FileOutputStream("error_log.txt"))); int x = 1/0; // Generates an exception } catch(Exception e) { // The error message is now written to error_log.txt System.err.println("Error: " + e.getMessage()); } } }In this example, we use setErr to redirect errors generated by our code to a file named "error_log.txt". After setting the error stream to the file, we generate an exception and catch it. When the exception is caught, the error message is written to the error_log.txt file. Package Library: java.lang.
