Java encoding Script

        System.out.println(System.getProperty("file.encoding")); //获取Project的encoding
        
         String S1="中文123";
         
         System.out.println("Default:"+S1.getBytes());
         System.out.println("Default:"+S1.getBytes());//每次 得到的并不一样
         System.out.println("UTF-8:"+S1.getBytes("UTF-8"));
         System.out.println("GB2312:"+S1.getBytes("GB2312"));
         System.out.println();
        
        
         byte[] BDefault= S1.getBytes();//得到原始的字节串；
         byte[] BUTF8= S1.getBytes("UTF-8");        
         byte[] BGBK = S1.getBytes("GB2312");
                 
         String SDefualt = new String(BDefault);  //根据原始的字节串，得到原始字符
         String SUTF8 = new String(BUTF8, "UTF-8");
         String SGBK = new String(BGBK, "GB2312");
        
         System.out.println(BDefault);
         System.out.println("Default返回String："+SDefualt);
