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]


我想将此文件(如[1","Low-level programming language",true]和其他文件)分成5种类型的字符串变量。

最佳答案

您可以拆分一个简单的正则表达式:

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


您不想只用逗号分开,因为您只希望方括号之间的逗号。

这是一个更完整的示例(如果需要,还有一个放在括号中的正则表达式)

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]);
}
