2. 使用return3. 使用Breaks对象中的break方法:import scala.util.control.Breaks._breakable {for (...) {if (...) break; // Exits the breakable block...}}3 数组1 2 3 4 5 6 7 val greetStrings = new Array[String](3) //或者 val numNames = Array("zero", "one", "two") scala>...
// Now print returned values using another loop. for( a <- retVal){ println( "Value of a: " + a ); } } def addInt( a:Int, b:Int ) : Int = { var sum:Int = 0 sum = a + b return sum } 模式匹配包括替代的序列,每个开始使用关键字case def main(args: Array[String]) { pr...
AI代码解释 def functionName ([参数列表]) : [return type] = { function body return [expr] } 以上代码中 return type 可以是任意合法的 Scala 数据类型。参数列表中的参数可以使用逗号分隔。 如果方法没有返回值,可以返回为 Unit,这个类似于 Java 的 void, 实例如下: 代码语言:scala AI代码解释 object H...
util.HashMap[String, Int] = {one=1, two=2} However, it’s not possible to implement a similar extractor for Java’s HashSet and combine them into one match expression (because there are two possible return values, not one): // src/script/scala/progscala3/patternmatching/Unapply...
The second method to map both keys and values is Map::flatMap. As with other Scala collections, flatMap flattens the collections returned by the mapping function into a single, flat one. As before, Map::flatMap comes in two flavors, as the mapping function can either return a single ele...
Functions that accept other functions as parameters and/or use functions as return values are known as higher-order functions. You may have heard of two of the most famous higher-order functions, map() and reduce(). The map() higher-order function takes a function parameter and uses it to...
