java 字符串写入word JAVA 将字符串hollow 替换成word肿么实现?

试试吧，注意要在所读取的文件里在每一行前加一个空格啊，然后测试就可以了

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.InputStream;

import java.io.InputStreamReader;

import java.io.OutputStream;

import java.io.OutputStreamWriter;

import java.io.Reader;

import java.io.Writer;

public class Excise_1 {

public void readFile(){

InputStream is;

Reader r ;

BufferedReader br ;

String newtext = "";

try {

is = new FileInputStream("d:/test.txt");

r = new InputStreamReader(is);

br = new BufferedReader(r);

while(br.read()!=-1){

String text = br.readLine();

newtext += text.replace("hello","world");

}

writeFile(newtext);

} catch (FileNotFoundException e) {

e.printStackTrace();

} catch (IOException e) {

e.printStackTrace();

}

}

public void writeFile(String newText){

OutputStream out;

Writer w ;

BufferedWriter bw;

try {

out = new FileOutputStream("d:/test.txt");

w = new OutputStreamWriter(out);

bw = new BufferedWriter(w);

bw.write(newText);

bw.flush();

} catch (FileNotFoundException e) {

e.printStackTrace();

} catch (IOException e) {

e.printStackTrace();

}

}

public static void main(String[] args) {

Excise_1 e = new Excise_1();

e.readFile();

}

}
