Astring literalis a series of characters in the source code that is enclosed in double quotes. For example, "falcon" is a string literal. Scala String simple example The first example is a simple Scala string example. main.scala @main def main() = val w = "an old falcon" println(w) ...
Finally, we can also use external libs like Apache Commons StringUtils class, which provides many useful methods like chop: scala> StringUtils.chop("abc") val res0: String = ab The method behaves very similarly to the init() method we saw before, as it removes the last character of the ...
In such situations, when we want to do a case-insensitive comparison, we can convert both the Strings to upper case or lower case and then compare: assert(stringOne.toUpperCase() == stringTwo.toUpperCase()) Finally, we should also be aware that calling such methods on a null String throws...

在反应式Java中,`Mono<String>` 是一个表示异步计算结果的类,它可能包含一个字符串值,也可能不包含(即完成时为空)。要从 `Mono<String>` 中获取字符串,通常不建议直接阻塞...
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 ...

It’s defined in the StringOps class, among other useful extension methods. It returns true if the String contains at least one character and false otherwise. It doesn’t treat white spaces as empty: scala> val str1: String = "Hello" scala> val str2: String = "" scala> val str3: ...
ve implemented several methods to ensure the uniform case of aString, it’s important to write tests to validate the accuracy of our implementations. We can utilizeScalaTestfor writing unit tests.
