Java如何从数组中获取某些单词[关闭]

Question

我有一个存储的数组

Array[0] = "Information of student, Class Allocated: 2B (13), Class Opposite: 1B (12)"
Array[1] = "Information of student, Class Allocated: 1B (12), Class Opposite: 2B (13)"
Array[2] = "Information of student, Class Allocated: 1A (10), Class Opposite: 2A (11)"

我需要Class Allocated：和Class Opposite的信息。因此我需要获得 2B 和 13 但存储在不同的变量中。哪个可以

For Array[0]
Floor = 2B
ClassNo = 13
Opposite = 1B
OppositeClass = 12

谁能告诉我如何获得它？非常感谢您的帮助。

Answer 1

在String中使用split方法。

假设你有标准格式。

String [] commasplit = Array[0].split(",");

然后

String [] allocated = commasplit[1].split(" : ");
String allocatedValue = allocated[1] //2B (13)

给定代码，用方法参数写一个泛型方法，这样你就不会写多次了。
