Strings. String have characters, and may certain values. With string manipulation methods in Scala 3.3, we can capitalize the first letter in this string. In this language, we can access many functions that act upon strings. To uppercase the first letter, we invoke "capitalize" on a string...
直接使用Scala描述新的语法很方便(有编译器支持)。 SQL解析器在BI中的应用不是很多,主要是用于: 解析用户输入的“自定义字段”的聚合类型: 普通聚合函数、窗口函数、普通函数 对于用户输入的SQL做一些高级分析,比如:判断是否有性能问题,是否可以优化等 另外,SQL Parser并不是本文的中心内容,所以,不再深入讨论,感兴...
Scala programming language has a huge library that supports the working data types. For string also there are methods in Scala to support its functioning. For string, one common usage is related to printing results of the program. Now for this many times, there are a lot of constraints neede...
TheregionMatches()method in Scala is used to check if the given region (substring) is common between the two strings or not. It checks both the string regions for equal and returns aBooleanvalue based on the comparison. The case difference between the two methods can be ignored by using the...

For Scala, we have access to both Java methods and Scala-specific methods. The indexOf method on List can take 1 or 2 arguments. IndexOfSlice and indexWhere are also available.Dot Net Perls is a collection of tested code examples. Pages are continually updated to stay current, with code ...
其实fastjson 默认是基于方法clz.getMethods()进行字段查找过滤的,而scala中的getter和setter方法完全不是java那种命名方式。scala中的getter:def foo():T setter: def foo_(val:T):Unit因此如果采用默认配置序列化scala对象,会出现如上问题。但是我们可以加上BeanProperty,目的是让这个类有getter和setter方法 ...

You can use the little known "QP brackets" to delimit scala expressions within strings. This has an advantage over other methods in that you can use any scala expression, not just simple vals/vars. Just use an opening "+ and closing +" bracket delimiters. Example: val name = "Joe Schmoe...
