This is helpful, for instance, if you’re error logging to the file and body of an e-mail. Create a new subclass of OutputStream called TeeOutputStream like this:
package be.marble.io;import java.io.*;public class TeeOutputStream extends OutputStream { private OutputStream out1, out2; public TeeOutputStream(OutputStream out1, OutputStream out2) { this.out1 = out1; this.out2 = out2; } public void write(byte b) throws IOException { out1.write(b); out2.write(b); } public void flush() throws IOException { out1.flush(); out2.flush(); } public void close() throws IOException { out1.close(); out2.close(); }}Charlie has over a decade of experience in website administration and technology management.
