c# - 如何像 C# 那样在 Java 中实现字符串拆分方法

Question

在 C# 中，如果我有这样一个字符串:

String test = ";;;;";
String[] split = test.Split(';');
Console.WriteLine(split.Length); // Then I got 5 here

但是在 Java 中:

String test = ";;;;";
String[] split = test.split(";");
System.out.println(split.length); // Then I got only 1 here

Answer 1

尝试:

  String test = ";;;;";
  String[] split = test.split(";", -1);
  System.out.println(split.length);

String API解释了此方法重载，它还添加了一个限制字段。

If n is non-positive then the pattern will be applied as many times as possible and the array can have any length.
