Java:用整数替换字符串

Question

我是新来的，所以我希望我能正确描述这个问题，并在我更了解 Java 之类的东西时帮助其他人。

但这就是我来这里的原因...我需要转换给定的文本文件，这样我就可以在名为“SUBDUE”的程序中使用它。

文件中给定图表的格式如下所示:

v 2_i_6 startevent

v 2_i_7 endevent

v 2_i_1 task
v 2_i_2 task
v 2_i_3 task
v 2_i_4 task
v 2_i_5 task

v 2_i_15 and
v 2_i_17 and
v 2_i_14 xor
v 2_i_16 xor
v 2_i_18 xor
v 2_i_19 xor

但是对于程序来说，该文件中的图表需要如下所示:

v 1 startevent

v 2 endevent

v 3 task
v 4 task
v 5 task
v 6 task
v 7 task

v 8 and
v 9 and
v 10 xor
v 11 xor
v 12 xor
v 13 xor

起初我以为我会手工完成。但我意识到有2000个。所以我尝试用Java编写一个程序。

这就是我得到的:

public class Input {

HashMap<String, Integer> replacements = new HashMap<String, Integer>();

public void readFile() throws IOException {

    FileReader fr = new FileReader(
            "file.txt");
    BufferedReader br = new BufferedReader(fr);
    String line = null;
    StringBuilder sb = new StringBuilder();
    int i = 0;

    while ((line = br.readLine()) != null) {

        if (line.startsWith("%")) {//every graph starts with % and a number so i know which graph is currently in progress
            i = 0;
        }
        if (line.startsWith("v")) {
            i++;
            replacements.put(line.split(" ")[1], i);
        }
    }
    fr.close();

    fr = new FileReader("file.txt");
    br = new BufferedReader(fr);
    while ((line = br.readLine()) != null) {
        for (Entry<String, Integer> e : replacements.entrySet()) {
            line = line.replaceAll(e.getKey().toString(), e.getValue().toString());
            line.toString();
        }
        sb.append(line);
        System.out.println(line);
        try {
            Thread.sleep(100);
        } catch (InterruptedException e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        }
    }
    fr.close();

    FileWriter fw = new FileWriter(
            new File("file.txt"));
    fw.write(sb.toString());
    fw.close();
}

当我启动程序时，它大部分转换正确，但有时会发生这种情况:

v 1 startevent

v 2 endevent

v 3 task
v 4 task
v 5 task
v 6 task
v 7 task

v 35 and
v 37 and
v 34 xor
v 36 xor
v 38 xor
v 39 xor

我开始调试，但放弃了，因为我需要遍历整个 map ，直到找到正确的键..所以我删除了 i++在第一while-loop ，所以i是0每时每刻。并得到了这样的东西:

v 0 startevent

v 0 endevent

v 0 task
v 0 task
v 0 task
v 0 task
v 0 task

v 05 and
v 07 and
v 04 xor
v 06 xor
v 08 xor
v 09 xor

但我不知道为什么它只替换了两位数的第一个数字。

我希望有人给我一个提示，或者更好的选择来按照我想要的方式替换这些字符串。

感谢您的回答。

因为这里要求的是我文件的前三张图表。很抱歉给您带来不便，

Answer 1

这可以作为起点。分割字符串似乎是更好的方法。

public static void main(String[] args) {
    // TODO code application logic here
    String [] input = {"v 2_i_6 startevent", "", "v 2_i_7 endevent"};

    for(int i = 0; i < input.length; i++)
    {
        System.out.println(myStringFormatter(input[i]));
    }
}

static String myStringFormatter(String input)
{
    if(input.length() > 0)
    {
        String[] processing = input.split(" ");//Splits the string  into 3 parts v, 2_i_6, and startevent
        String[] processing2 = processing[1].split("_");//Splits 2_i_6 into 3 parts 2, i, and 6

        return processing[0] + " " + processing2[2] + " " + processing[2]; //Takes the first part of the first split, the third part of the second split, and the third part of the first split and put them back together separated by a space
    }

    return "";//If it gets an empty string, its going to return an empty string
}

Output
