一、緩衝讀取文本:
關鍵點:
(1).
BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream));
(2).循環判斷條件
String temp = br.readLine() != null;
package pdfSearchKeyWords;
import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
public class ReadAndWrite {
public static void main(String[] args){
String path = "C:\\Users\\Administrator\\Desktop\\jar\\lxl.txt";
String tagPath = "C:\\Users\\Administrator\\Desktop\\lxl.txt";
copyTxt(path,tagPath);
}
public static void copyTxt(String path,String tagPath){
FileInputStream fis = null;
InputStreamReader reader =null;
BufferedReader br = null;
StringBuffer sb = new StringBuffer();
BufferedWriter bw = null;
try {
//fis = new FileInputStream("C:\\Users\\Administrator\\Desktop\\jar\\lxl.txt");
fis = new FileInputStream(path);
reader = new InputStreamReader(fis);
br = new BufferedReader(reader);
String temp=null;
while((temp = br.readLine())!=null){
sb.append(temp);
}
//bw = new BufferedWriter(new OutputStreamWriter(new FileOutputStream("C:\\Users\\Administrator\\Desktop\\lxl.txt")));
bw = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(tagPath)));
System.out.println(sb);
bw.write(sb.toString());
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} finally{
try {
br.close();
reader.close();
fis.close();
bw.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
}
