1. java如何按行數讀取txt 比如我要讀第10行到第100行 或者第1000行 到 第1200 行

用LineNumberReader行號讀取器
FileReader f=new FileReader("test.txt");
LineNumberReader l=new LineNumberReader(f);
l.setLineNumber(10); //跳到第10行
for(int i=10;i<=100;i++){
System.out.println( l.readLine()); //顯示第10-100行
}
l.close();
f.close();

2. bson 是一種什麼數據格式java中常用嗎和json啥區別啊

java中沒有BSON,xml和json比較常用

BSON是由10gen開發的一個數據格式，目前主要用於MongoDB中，是MongoDB的數據存儲格式。BSON基於JSON格式，選擇JSON進行改造的原因主要是JSON的通用性及JSON的schemaless的特性。
BSON主要會實現以下三點目標：
1.更快的遍歷速度
對JSON格式來說，太大的JSON結構會導致數據遍歷非常慢。在JSON中，要跳過一個文檔進行數據讀取，需要對此文檔進行掃描才行，需要進行麻煩的數據結構匹配，比如括弧的匹配，而BSON對JSON的一大改進就是，它會將JSON的每一個元素的長度存在元素的頭部，這樣你只需要讀取到元素長度就能直接seek到指定的點上進行讀取了。
2.操作更簡易
對JSON來說，數據存儲是無類型的，比如你要修改基本一個值，從9到10，由於從一個字元變成了兩個，所以可能其後面的所有內容都需要往後移一位才可以。而使用BSON，你可以指定這個列為數字列，那麼無論數字從9長到10還是100，我們都只是在存儲數字的那一位上進行修改，不會導致數據總長變大。當然，在MongoDB中，如果數字從整形增大到長整型，還是會導致數據總長變大的。
3.增加了額外的數據類型
JSON是一個很方便的數據交換格式，但是其類型比較有限。BSON在其基礎上增加了「byte array」數據類型。這使得二進制的存儲不再需要先base64轉換後再存成JSON。大大減少了計算開銷和數據大小。
當然，在有的時候，BSON相對JSON來說也並沒有空間上的優勢，比如對{「field」:7}，在JSON的存儲上7隻使用了一個位元組，而如果用BSON，那就是至少4個位元組（32位）
目前在10gen的努力下，BSON已經有了針對多種語言的編碼解碼包。並且都是Apache 2 license下開源的。並且還在隨著MongoDB進一步地發展。關於BSON，

3. Java如何將文本文檔中的字元串讀取到字元串數組

使用RandomAccessFile先讀取一次計算行數，seek重置到文件頭部，再讀取每行，賦值給a數組。

importjava.io.FileNotFoundException;
importjava.io.IOException;
importjava.io.RandomAccessFile;
publicclassTest{
//此題目關鍵是根據文件內容確定二維數組的行數和列數
publicstaticvoidmain(String[]args){
RandomAccessFilereader=null;
try{
reader=newRandomAccessFile("test.txt","r");
intn=0;//行數
while(reader.readLine()!=null){//第一次按行讀取只為了計算行數
n++;
}
String[][]a=newString[n][];
reader.seek(0);//重置到文件頭部
intj;
Stringline;
String[]strs;
inti=0;
while((line=reader.readLine())!=null){//第二次按行讀取是真正的讀取數據
strs=line.split("");//把讀取到的一行數據以空格分割成子字元串數組
a[i]=newString[strs.length];//列數就是數組strs的大小，此句是逐行創建二維數組的列
for(j=0;j<strs.length;j++){
a[i][j]=strs[j];//逐行給二維數組的每一列賦值
}
i++;
}
for(i=0;i<n;i++){
for(j=0;j<a[i].length;j++){
System.out.println("a["+i+"]["+j+"]="+a[i][j]);
}
}
}catch(FileNotFoundExceptione){
e.printStackTrace();
}catch(IOExceptione){
e.printStackTrace();
}finally{
if(reader!=null){
try{
reader.close();
reader=null;
}catch(IOExceptione){
e.printStackTrace();
}
}
}
}
}

運行結果如圖

4. JAVA 的輸入輸出，讀取寫入文件

//將內容追加到文件尾部
import java.io.FileWriter;
import java.io.IOException;
import java.io.RandomAccessFile;

/**
* 將內容追加到文件尾部
*/
public class AppendToFile {

/**
* A方法追加文件：使用File
* @param fileName 文件名
* @param content 追加的內容
*/
public static void appendMethodA(String fileName, String content){
try {
// 打開一個隨機訪問文件流，按讀寫方式
RandomAccessFile randomFile = new RandomAccessFile(fileName, "rw");
// 文件長度，位元組數
long fileLength = randomFile.length();
//將寫文件指針移到文件尾。
randomFile.seek(fileLength);
randomFile.writeBytes(content);
randomFile.close();
} catch (IOException e){
e.printStackTrace();
}
}
/**
* B方法追加文件：使用FileWriter
* @param fileName
* @param content
*/
public static void appendMethodB(String fileName, String content){
try {
//打開一個寫文件器，構造函數中的第二個參數true表示以追加形式寫文件
FileWriter writer = new FileWriter(fileName, true);
writer.write(content);
writer.close();
} catch (IOException e) {
e.printStackTrace();
}
}

public static void main(String[] args) {
String fileName = "C:/temp/newTemp.txt";
String content = "new append!";
//按方法A追加文件
AppendToFile.appendMethodA(fileName, content);
AppendToFile.appendMethodA(fileName, "append end. ");
//顯示文件內容
ReadFromFile.readFileByLines(fileName);
//按方法B追加文件
AppendToFile.appendMethodB(fileName, content);
AppendToFile.appendMethodB(fileName, "append end. ");
//顯示文件內容
ReadFromFile.readFileByLines(fileName);
}
}

6. java生成word文檔的問題

Jacob解決Word文檔的讀寫問題收藏
Jacob 是Java-COM Bridge的縮寫，它在Java與微軟的COM組件之間構建一座橋梁。使用Jacob自帶的DLL動態鏈接庫，並通過JNI的方式實現了在Java平台上對COM程序的調用。Jacob下載的地址為：

http://sourceforge.net/project/showfiles.php?group_id=109543&package_id=118368

配置：

(1)將解壓包中的jacob.dll（x86常用,x64)拷到jdk安裝目錄下的jre\bin文件夾或windows安裝路徑下的WINDOWS\system32文件夾下

(2)將jacob.jar文件拷到classpath下即可

常見問題解決:

對於」java.lang.UnsatisfiedLinkError: C:\WINDOWS\system32\jacob-1.14.3-x86.dll: 由於應用程序配置不正確，應用程序未能啟動。重新安裝應用程序可能會糾正」這個問題,可以通過

重新下載Jacob的jar及dll文件(最好版本比現在的低,如1.11)解決
