如何在android中提取這個字符串變量？

Question

String test=
      ["1","Low-level programming language",true],
      ["2","High level programming language",false],
      ["3","Machine language",false],["4","All of the above",false],
      ["5","None of these",false]

我想將這個文件像[1","Low-level programming language",true]和其他文件分成5種類型的字符串變量。

你可以拆分一個簡單的正則表達式：

String [] splitStrings = test.split("\\],\\[");

您不希望僅使用逗號分割，因為您只需要方括號之間的逗號。

這是一個更完整的示例（如果需要，還可以使用括號中的正則表達式）

public static void main(String []args){
    String test="[\"1\",\"Low-level programming language\",true],[\"2\",\"High level programming language\",false],[\"3\",\"Machine language\",false],[\"4\",\"All of the above\",false],[\"5\",\"None of these\",false]";
    String [] splitStrings = test.split("(?!\\]),(?=\\[)");

    System.out.println(splitStrings[0]);
    System.out.println(splitStrings[1]);
    System.out.println(splitStrings[2]);
    System.out.println(splitStrings[3]);
    System.out.println(splitStrings[4]);
}
