Java：如何将格式为{i，j}，{i，j}，{i，j}的字符串文本文件转换为二维数组？

我的文本文件如下： {11-11,22}，{33-33,44}，{88-88,99}

如何将其转换为Java中的二维数组，格式如下： [11-11,22]，[33-33,44]，…[88-88,99]

公共静态void main（字符串[]args）{
public static void main(String[] args) {
    Scanner in = new Scanner(Thread.currentThread().getContextClassLoader().
    getResourceAsStream("input/test.txt"));
    String line = in.nextLine();
    String[] tokens = line.split("},");
    String[][] finalArray = new String[tokens.length][2];
    for (int i = 0; i < tokens.length; i++) {
        tokens[i] = tokens[i].replace("{", "");
        tokens[i] = tokens[i].replace("}", "");
        finalArray[i] = tokens[i].split(",");
    }
    for (int i = 0; i < finalArray.length; i++) {
        System.out.println(Arrays.toString(finalArray[i]));
    }
}

Scanner in=新扫描仪（Thread.currentThread（）.getContextClassLoader（）。
getResourceAsStream（“input/test.txt”）；
String line=in.nextLine（）；
String[]tokens=line.split（“}”）；
字符串[][]finalArray=新字符串[tokens.length][2]；
for（int i=0；i

解决方案：

嗯，

[[11-11,22]，[33-33,44]，…[88-88,99]

到底代表什么？什么是

11-11

？字符串？到目前为止，您为实现此目标做了哪些工作？---text.txt:{11-11,22}，{33-33,44}，{88-88,99}输出：[11-11,22][33-33,44][88-88,99]

    String source = "{11-11,22},{33-33,44},{88-88,99}";
    String[] splittedSource = source.split("(?<=\\}),(?=\\{)");
    Pattern p = Pattern.compile("\\{([^,]+),([^\\}]+)");
    String[][] result = new String[splittedSource.length][2];
    for(int i = 0; i < splittedSource.length; i++) {
        Matcher m = p.matcher(splittedSource[i]);
        while(m.find()) {
            result[i][0] = m.group(1);
            result[i][1] = m.group(2);
            System.out.print(m.group(1) + " " + m.group(2) + "\n");
        }
    }
    System.out.println(Arrays.deepToString(result));

11-11 22
33-33 44
88-88 99
[[11-11, 22], [33-33, 44], [88-88, 99]]
