問題描述
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]
我想把這個文件像[1","Low-level programming language",true]等分成5種字符串變量.
I want to separate this file like [1","Low-level programming language",true] and others into 5 types of string variables.
推薦答案
你可以在一個簡單的正則表達式上拆分:
You could split on a simple regex:
String [] splitStrings = test.split("\],\[");
你不想只用逗號分割，因為你只想要方括號之間的逗號.
You don't want to split on just comma because you only want the commas between the square brackets.
這是一個更完整的示例(如果需要，還有一個正則表達式可以保留括號)
Here is a more complete example (and a regex that holds onto the brackets if you want)
public static void main(String []args){
String test="["1","Low-level programming language",true],["2","High level programming language",false],["3","Machine language",false],["4","All of the above",false],["5","None of these",false]";
String [] splitStrings = test.split("(?!\]),(?=\[)");
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]);
}
