Examples of java.io.PrintWriter

java.io.PrintWriter
PrintWriter is a class which takes either an OutputStream or Writer and provides convenience methods for printing common data types in a human readable format on the stream. No IOExceptions are thrown by this class. Instead, callers should call checkError() to see if a problem has been encountered in this Writer.

        ProxyCodeGenerator cg = new ProxyCodeGenerator();
        cg.setPackageName("bytecode");
        cg.generateClassProxy(c);
        StringWriter sw = new StringWriter();
        cg.write(new PrintWriter(sw));
        String code = sw.toString();
        String proxy = "bytecode."+ c.getSimpleName() + "Proxy";
        compiler.setSource(proxy, code);
        // System.out.println(code);
        Class<?> px = compiler.getClass(proxy);
