近些日子碰到了一个状况, Java去读取文本文件, 像是csv文件、txt文件一类的, 一旦碰到中文就会变为乱码。推荐: java视频教程读取代码如下List linesnew ArrayList(); BufferedReader br new BufferedReader(new FileReader(fileName)); String line null; while ((line br.readLine()) ! null) { lines.add(line); } br.close();linesnew ArrayList(); BufferedReader br new BufferedReader(new FileReader(fileName)); String line null; while ((line br.readLine()) ! null) { lines.add(line); } br.close();原理Java的I/O类处理如图和类是Java的I/O里读字符的父类, 接着类是读字节的父类, 随后类是关联字节到字符的桥梁, 它承担在I/O进程里处理读取字节到字符的转换, 然而具体字节到字符的解码实现它是由去实现。进行解码时, 编码格式必须由用户予以指定。此外, 需要留意的是, 如果未曾指定, 那么将会采用本地环境里的默认字符集, 比如说, 在中文环境中会采用GBK编码。导入或其他的JAVA项目的正确方法 WORD版这份文档着重讲的是, 把其他的JAVA项目导入的正确方式, 期望这份文档, 能给有需求的友人送去帮助, 有兴趣的朋友能够过来瞧瞧。下载归纳, 在Java读取数据流之际, 务必要明确指定数据流的编码方式不然的话就会运用本地环境裹的默认字符集。经过上述分析修改之后的代码如下List linesnew ArrayList(); BufferedReader brnew BufferedReader(new InputStreamReader(new FileInputStream(fileName),UTF-8)); String line null; while ((line br.readLine()) ! null) { lines.add(line); } br.close();linesnew ArrayList(); BufferedReader brnew BufferedReader(new InputStreamReader(new FileInputStream(fileName),UTF-8)); String line null; while ((line br.readLine()) ! null) { lines.add(line); } br.close();更多知识请关注java基础教程栏目。WwW.HoUniAoHaO.CoM/AuSt/60628.htmlWwW.HoUniAoHaO.CoM/AuSt/60629.htmlWwW.HoUniAoHaO.CoM/AuSt/60630.htmlWwW.HoUniAoHaO.CoM/AuSt/60631.htmlWwW.HoUniAoHaO.CoM/AuSt/60632.htmlWwW.HoUniAoHaO.CoM/AuSt/60633.htmlWwW.HoUniAoHaO.CoM/AuSt/60634.htmlWwW.HoUniAoHaO.CoM/AuSt/60635.htmlWwW.HoUniAoHaO.CoM/AuSt/60636.htmlWwW.HoUniAoHaO.CoM/AuSt/60637.htmlWwW.HoUniAoHaO.CoM/AuSt/60638.htmlWwW.HoUniAoHaO.CoM/AuSt/60639.htmlWwW.HoUniAoHaO.CoM/AuSt/60640.htmlWwW.HoUniAoHaO.CoM/AuSt/60641.htmlWwW.HoUniAoHaO.CoM/AuSt/60642.htmlWwW.HoUniAoHaO.CoM/AuSt/60643.htmlWwW.HoUniAoHaO.CoM/AuSt/60644.htmlWwW.HoUniAoHaO.CoM/AuSt/60645.htmlWwW.HoUniAoHaO.CoM/AuSt/60646.htmlWwW.HoUniAoHaO.CoM/AuSt/60647.htmlWwW.HoUniAoHaO.CoM/AuSt/60648.htmlWwW.HoUniAoHaO.CoM/AuSt/60649.htmlWwW.HoUniAoHaO.CoM/AuSt/60650.htmlWwW.HoUniAoHaO.CoM/AuSt/60651.htmlWwW.HoUniAoHaO.CoM/AuSt/60652.htmlWwW.HoUniAoHaO.CoM/AuSt/60653.htmlWwW.HoUniAoHaO.CoM/AuSt/60654.htmlWwW.HoUniAoHaO.CoM/AuSt/60655.htmlWwW.HoUniAoHaO.CoM/AuSt/60656.htmlWwW.HoUniAoHaO.CoM/AuSt/60657.htmlWwW.HoUniAoHaO.CoM/AuSt/60658.htmlWwW.HoUniAoHaO.CoM/AuSt/60659.htmlWwW.HoUniAoHaO.CoM/AuSt/60660.htmlWwW.HoUniAoHaO.CoM/AuSt/60661.htmlWwW.HoUniAoHaO.CoM/AuSt/60662.htmlWwW.HoUniAoHaO.CoM/AuSt/60663.htmlWwW.HoUniAoHaO.CoM/AuSt/60664.htmlWwW.HoUniAoHaO.CoM/AuSt/60665.htmlWwW.HoUniAoHaO.CoM/AuSt/60666.htmlWwW.HoUniAoHaO.CoM/AuSt/60667.htmlWwW.HoUniAoHaO.CoM/AuSt/60668.htmlWwW.HoUniAoHaO.CoM/AuSt/60669.htmlWwW.HoUniAoHaO.CoM/AuSt/60670.htmlWwW.HoUniAoHaO.CoM/AuSt/60671.htmlWwW.HoUniAoHaO.CoM/AuSt/60672.htmlWwW.HoUniAoHaO.CoM/AuSt/60673.htmlWwW.HoUniAoHaO.CoM/AuSt/60674.htmlWwW.HoUniAoHaO.CoM/AuSt/60675.htmlWwW.HoUniAoHaO.CoM/AuSt/60676.htmlWwW.HoUniAoHaO.CoM/AuSt/60677.htmlWwW.HoUniAoHaO.CoM/AuSt/60678.htmlWwW.HoUniAoHaO.CoM/AuSt/60679.htmlWwW.HoUniAoHaO.CoM/AuSt/60680.htmlWwW.HoUniAoHaO.CoM/AuSt/60681.htmlWwW.HoUniAoHaO.CoM/AuSt/60682.htmlWwW.HoUniAoHaO.CoM/AuSt/60683.htmlWwW.HoUniAoHaO.CoM/AuSt/60684.htmlWwW.HoUniAoHaO.CoM/AuSt/60685.htmlWwW.HoUniAoHaO.CoM/AuSt/60686.htmlWwW.HoUniAoHaO.CoM/AuSt/60687.htmlWwW.HoUniAoHaO.CoM/AuSt/60688.htmlWwW.HoUniAoHaO.CoM/AuSt/60689.htmlWwW.HoUniAoHaO.CoM/AuSt/60690.htmlWwW.HoUniAoHaO.CoM/AuSt/60691.htmlWwW.HoUniAoHaO.CoM/AuSt/60692.htmlWwW.HoUniAoHaO.CoM/AuSt/60693.htmlWwW.HoUniAoHaO.CoM/AuSt/60694.htmlWwW.HoUniAoHaO.CoM/AuSt/60695.htmlWwW.HoUniAoHaO.CoM/AuSt/60696.htmlWwW.HoUniAoHaO.CoM/AuSt/60697.htmlWwW.HoUniAoHaO.CoM/AuSt/60698.htmlWwW.HoUniAoHaO.CoM/AuSt/60699.htmlWwW.HoUniAoHaO.CoM/AuSt/60700.htmlWwW.HoUniAoHaO.CoM/AuSt/60701.htmlWwW.HoUniAoHaO.CoM/AuSt/60702.htmlWwW.HoUniAoHaO.CoM/AuSt/60703.htmlWwW.HoUniAoHaO.CoM/AuSt/60704.htmlWwW.HoUniAoHaO.CoM/AuSt/60705.htmlWwW.HoUniAoHaO.CoM/AuSt/60706.htmlWwW.HoUniAoHaO.CoM/AuSt/60707.htmlWwW.HoUniAoHaO.CoM/AuSt/60708.htmlWwW.HoUniAoHaO.CoM/AuSt/60709.htmlWwW.HoUniAoHaO.CoM/AuSt/60710.htmlWwW.HoUniAoHaO.CoM/AuSt/60711.htmlWwW.HoUniAoHaO.CoM/AuSt/60712.htmlWwW.HoUniAoHaO.CoM/AuSt/60713.htmlWwW.HoUniAoHaO.CoM/AuSt/60714.htmlWwW.HoUniAoHaO.CoM/AuSt/60715.htmlWwW.HoUniAoHaO.CoM/AuSt/60716.htmlWwW.HoUniAoHaO.CoM/AuSt/60717.htmlWwW.HoUniAoHaO.CoM/AuSt/60718.htmlWwW.HoUniAoHaO.CoM/AuSt/60719.htmlWwW.HoUniAoHaO.CoM/AuSt/60720.htmlWwW.HoUniAoHaO.CoM/AuSt/60721.htmlWwW.HoUniAoHaO.CoM/AuSt/60722.htmlWwW.HoUniAoHaO.CoM/AuSt/60723.htmlWwW.HoUniAoHaO.CoM/AuSt/60724.htmlWwW.HoUniAoHaO.CoM/AuSt/60725.htmlWwW.HoUniAoHaO.CoM/AuSt/60726.htmlWwW.HoUniAoHaO.CoM/AuSt/60727.htmlWwW.HoUniAoHaO.CoM/AuSt/60728.htmlWwW.HoUniAoHaO.CoM/AuSt/60729.htmlWwW.HoUniAoHaO.CoM/AuSt/60730.htmlWwW.HoUniAoHaO.CoM/AuSt/60731.htmlWwW.HoUniAoHaO.CoM/AuSt/60732.htmlWwW.HoUniAoHaO.CoM/AuSt/60733.htmlWwW.HoUniAoHaO.CoM/AuSt/60734.htmlWwW.HoUniAoHaO.CoM/AuSt/60735.htmlWwW.HoUniAoHaO.CoM/AuSt/60736.htmlWwW.HoUniAoHaO.CoM/AuSt/60737.htmlWwW.HoUniAoHaO.CoM/AuSt/60738.htmlWwW.HoUniAoHaO.CoM/AuSt/60739.htmlWwW.HoUniAoHaO.CoM/AuSt/60740.htmlWwW.HoUniAoHaO.CoM/AuSt/60741.htmlWwW.HoUniAoHaO.CoM/AuSt/60742.htmlWwW.HoUniAoHaO.CoM/AuSt/60743.htmlWwW.HoUniAoHaO.CoM/AuSt/60744.htmlWwW.HoUniAoHaO.CoM/AuSt/60745.htmlWwW.HoUniAoHaO.CoM/AuSt/60746.htmlWwW.HoUniAoHaO.CoM/AuSt/60747.htmlWwW.HoUniAoHaO.CoM/AuSt/60748.htmlWwW.HoUniAoHaO.CoM/AuSt/60749.htmlWwW.HoUniAoHaO.CoM/AuSt/60750.htmlWwW.HoUniAoHaO.CoM/AuSt/60751.htmlWwW.HoUniAoHaO.CoM/AuSt/60752.htmlWwW.HoUniAoHaO.CoM/AuSt/60753.htmlWwW.HoUniAoHaO.CoM/AuSt/60754.htmlWwW.HoUniAoHaO.CoM/AuSt/60755.htmlWwW.HoUniAoHaO.CoM/AuSt/60756.htmlWwW.HoUniAoHaO.CoM/AuSt/60757.htmlWwW.HoUniAoHaO.CoM/AuSt/60758.htmlWwW.HoUniAoHaO.CoM/AuSt/60759.htmlWwW.HoUniAoHaO.CoM/AuSt/60760.htmlWwW.HoUniAoHaO.CoM/AuSt/60761.htmlWwW.HoUniAoHaO.CoM/AuSt/60762.htmlWwW.HoUniAoHaO.CoM/AuSt/60763.htmlWwW.HoUniAoHaO.CoM/AuSt/60764.htmlWwW.HoUniAoHaO.CoM/AuSt/60765.htmlWwW.HoUniAoHaO.CoM/AuSt/60766.htmlWwW.HoUniAoHaO.CoM/AuSt/60767.htmlWwW.HoUniAoHaO.CoM/AuSt/60768.htmlWwW.HoUniAoHaO.CoM/AuSt/60769.htmlWwW.HoUniAoHaO.CoM/AuSt/60770.htmlWwW.HoUniAoHaO.CoM/AuSt/60771.htmlWwW.HoUniAoHaO.CoM/AuSt/60772.htmlWwW.HoUniAoHaO.CoM/AuSt/60773.htmlWwW.HoU
