String msg = "ab.cd12.ef"; String[] strings = msg.split("\\."); Kotlin在此基础上,通过扩展函数扩展字符串方法,通过默认参数实现重载效果。 /** * Splits this char sequence to a list of strings around occurrences of the specified [delimiters]. * * @param delimiters One or more strings ...
fun testListStringArgs(vararg values: String) { println(values.asList()) } val strArr= arrayOf("aa", "bb")//这里直接使用arrayOftestListStringArgs(*strArr) 4、因为是数组,所以不能使用listOf的方式, 如果非得要使用list的方式,则需要先转换为array: testListStringArgs(*strings.toTypedArray()) ...

可以使用Collection作为适用于不同集合类型的函数的参数。对于更具体的情况,请使用 Collection 的继承者:List与Set。 fun printAll(strings: Collection<String>) { for(s in strings) print("$s ") println() } fun main() { val stringList = listOf("one", "two", "one") ...
list3.add("d") println("e = $list3") println("last element = ${list3.last()}") val list4 = mutableMapOf<String, String>("1" to "A", "2" to "B") val list5 = mutableSetOf<String>("B", "C", "D") 1. 2.
valanyComparator=Comparator<Any>{e1,e2->e1.hashCode()-e2.hashCode()}valstrings=listOf("a","b","c")strings.sortedWith(anyComparator) sortedWith函数期望一个 Comparator<String> ,传递给它一个能比较更一般的类型的比较器是安全的。如果你要在特定类型的对象上执行比较,可以使用能处理该类型或者它的超...
