繁简体字符串转化的JAVA方式实现.doc

繁简体(GBBig5)字符串转化的JAVA方式实现本文提供一个java实现中文字符繁简体互换的zip包以及主要的源代码实现说明。 繁简体(GBBig5)中文字符的转化实现原理很简单，就是根据两种码表的编码规则，创建两者之间的字符对应关系表，通过程序读取这个映射表来自动查出另一种编码方式下对应字符的字节编码，从而进行逐字节的内容替换。 主功能实现的GB2Big5.java源代码如下: 查看复制到剪切板打印1. packagenet.java2000.tools; 2. 3. importjava.io.BufferedOutputStream; 4. importjava.io.FileOutputStream; 5. importjava.io.IOException; 6. importjava.io.InputStream; 7. 8. /* 9. *用来处理GB2312/BIG5码字符互相转换的类. 10. *需要两个码表文件:gb-big5.table,/zeal/util/big5-gb.table. 11. *这两个码表可以根据具体情况补充映射不正确的码. 12. */13. publicclassGB2Big5 14. privatestaticGB2Big5pInstance=null; 15. 16. privateStrings_big5TableFile=null; 17. 18. privateStrings_gbTableFile=null; 19. 20. privatebyteb_big5Table=null; 21. 22. privatebyteb_gbTable=null; 23. 24. /*指定两个码表文件来进行初始化*/25. privateGB2Big5(StringsgbTableFile,Stringsbig5TableFile)throwsNullPointerException 26. s_big5TableFile=sbig5TableFile; 27. s_gbTableFile=sgbTableFile; 28. if(null=b_gbTable) 29. b_gbTable=getBytesFromFile(sgbTableFile); 30. 31. if(null=b_big5Table) 32. b_big5Table=getBytesFromFile(sbig5TableFile); 33. 34. if(null=b_gbTable) 35. thrownewNullPointerException(Nogbtablecanbeload); 36. 37. if(null=b_big5Table) 38. thrownewNullPointerException(Nobig5tablecanbeload); 39. 40. 41. 42. publicstaticsynchronizedGB2Big5getInstance() 43. /returngetInstance(d:gb-big5.table,d:big5-gb.table); 44. returngetInstance(/net/java2000/tools/gb-big5.table,/net/java2000/tools/big5-gb.table); 45. 46. 47. publicstaticsynchronizedGB2Big5getInstance(StringsgbTableFile,Stringsbig5TableFile) 48. if(null=pInstance) 49. try 50. pInstance=newGB2Big5(sgbTableFile,sbig5TableFile); 51. catch(Exceptione) 52.
