question: private static void init ( ) { encoders = new HashMap ( ) ; encoders . put ( "jpeg" , "org.jfree.chart.encoders.SunJPEGEncoderAdapter" ) ; encoders . put ( "png" , "org.jfree.chart.encoders.SunPNGEncoderAdapter" ) ; }
target:  Sets up default encoders (uses Sun PNG Encoder if JDK 1.4+ and the SunPNGEncoderAdapter class is available).
