This article is about how java splits documents according to character length given a fixed length. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Given fixed length (array aa [])

Split the document according to the character length (non-byte length)

Finally, output the document with spaces removed to ^ splice.

The first class

Package work

Import java.io.BufferedReader

Import java.io.BufferedWriter

Import java.io.File

Import java.io.FileInputStream

Import java.io.FileWriter

Import java.io.IOException

Import java.io.InputStream

Import java.io.InputStreamReader

Import java.nio.charset.Charset

Public class T1 {

/ / inputFilePath input file path

Public static void parseCunegFile (String inputFilePath,String outputFilePath, int [] aa) throws Exception {

BufferedWriter bw = null

BufferedReader br = null

Int [] bb = new int [aa.length]

Bb [0] = 0

For (int I = 1; I

< bb.length; i++) { 　　bb[i] = bb[i - 1] + aa[i - 1]+1; 　　aa[i]=aa[i]-1; 　　} 　　try { 　　//读取输入的文件 　　File ifile = new File(inputFilePath); 　　InputStream is = new FileInputStream(ifile); 　　//没有则创建输出的文件 　　File ofile = new File(outputFilePath); 　　//FileOutputStream out=new FileOutputStream(ofile); 　　if(!ofile.exists()){ 　　ofile.createNewFile(); 　　} 　　bw=new BufferedWriter(new FileWriter(ofile,true)); 　　br = new BufferedReader(new InputStreamReader(is, Charset.forName("gbk"))); 　　String line = ""; 　　// 读取每一行 　　while ((line = br.readLine()) != null) { 　　String str = ""; 　　// 循环要获取的长度 　　for (int i = 0; i < aa.length; i++) { 　　str = str.trim()+T2.substringByte(line, bb[i], aa[i]).trim()+"^"; 　　}郑州人流多少钱 http://www.hnmt120.com/ 　　str = str.substring(0,str.length()-1); 　　bw.write(str+"\n"); 　　} 　　} catch (IOException e) { 　　e.printStackTrace(); 　　}finally { 　　br.close(); 　　bw.close(); 　　} 　　} 　　} 　　第二个class 　　package work; 　　public class T2 { 　　// orignal:需要截取的每一行 start：从第几位开始 count：截取几位 　　public static String substringByte(String orignal, int start, int count) throws Exception { 　　// 目标char Pull buff缓存区间; 　　StringBuffer buff = new StringBuffer(); 　　char c; 　　int len = 0; 　　// 遍历String的每一个Char字符，计算当前总长度 　　// 如果到当前Char的的字节长度大于要截取的字符总长度，则跳出循环返回截取的字符串。 　　for (int i = 0; i < orignal.toCharArray().length; i++) { 　　c = orignal.charAt(i); 　　len += String.valueOf(c).getBytes("GBK").length; 　　if (len >

/ / create a String object and pass in the target char Buff object

Return new String (buff)
