java - 在java中的两个字符之间拆分

Question

我想在两个分号 (:) 之间分割一个字符串。IE，

布尔值：咖啡先生 - 召回：8a42bb8b36a6b0820136aa5e05dc01b3:1346790794980

我在尝试

split("[\\:||\\:]");

但它不工作

Answer 1

使用带有“：”的拆分作为正则表达式。

更确切地说：

  String splits[] = yourString.split(":");
  //splits will contain: 
  //splits[0] = "BOOLEAN";
  //splits[1] = "Mr. Coffee - Recall";
  //splits[2] = "8a42bb8b36a6b0820136aa5e05dc01b3";
  //splits[3] = "1346790794980";

Answer 2

您可以使用split()，参考此代码，

String s ="BOOLEAN: Mr. Coffee - Recall:8a42bb8b36a6b0820136aa5e05dc01b3:1346790794980";

String temp = new String();


    String[] arr = s.split(":");

    for(String x : arr){
      System.out.println(x);
    }

Answer 3

这：

  String m = "BOOLEAN: Mr. Coffee - Recall:8a42bb8b36a6b0820136aa5e05dc01b3:1346790794980";
  for (String x : m.split(":"))
    System.out.println(x);

返回

BOOLEAN
 Mr. Coffee - Recall
8a42bb8b36a6b0820136aa5e05dc01b3
1346790794980

Answer 4

正则表达式风味：

    String yourString = "BOOLEAN: Mr. Coffee - Recall:8a42bb8b36a6b0820136aa5e05dc01b3:1346790794980";
    String [] componentStrings = Pattern.compile(":").split(yourString);

    for(int i=0;i<componentStrings.length;i++)
    {
        System.out.println(i + " - " + componentStrings[i]);
    }
