解析txt文件数据

Question

，因为我已经包含文本的文本文件：

VOLT=367 
CURRENT=0.07 
TEMP=031 
RPM=3780 
63HZ 
VOLT=288 
CURRENT=0.00 
TEMP=030 
RPM=3420 
57HZ 

等等.... 我想利用这个文本文件作为Java输入和创建一个输出的文本文件具有这种文字排列为：

367,0.07,031,3780,63 
288,0.00,030,3420,57 

依此类推，直到txt文件的末尾..

编码尝试至今：

import java.io.BufferedReader; 
import java.io.FileInputStream; 
import java.io.InputStreamReader; 

try { 
    FileInputStream fstream = new FileInputStream("file path\data.txt"); 
    BufferedReader br = new BufferedReader(new InputStreamReader(fstream)); 
    BufferedWriter brw = new BufferedWriter(new OutputStreamWriter(out)); 
    do { 
     for (int i=1;i<50;i++) { 
      //I dont know what to do here 
      ... 

Answer 1

试试这个，

String input = ""; 
br = new BufferedReader(new FileReader(inputFile)); 
out = new PrintWriter(outputFile); 
StringBuilder result = new StringBuilder(); 
while ((input = br.readLine()) != null) 
{ 
    if(input.contains("HZ")) 
    { 
     result.append(input.replace("HZ", "")); 
     result.append("\n"); 
    } 
    else 
    { 
     result.append(input.substring(input.indexOf("=") + 1, input.length())); 
     result.append(","); 
    } 
} 
System.out.println("result : "+result.toString()); 

Answer 2

使用这个简单的代码。

String res=""; 
while ((input = br.readLine()) != null) 
{ 
    if(input.indexOf("=")!= -1){ 
    res+=input.split("=+")[1]+","; 
    } 
    else{ 
    res+="\n"; 
    } 
} 
System.out.println("result : "+res.substring(0,res.length()-1));//To omit last ','
