Array fixed-length arraysIf you need an array of the same length, you can use the arrays in Scala. For example:val numsArray = new Array[Int] (30) //长度为30的整数数组,所有元素初始化为0val stringArrays = new Array [String] (30) //长度为30的字符串数组,所有元素初始化为nullval sHello = Array("Hello", "World") //长度为2的Array[String]类型是推断出来的,已提供初始值就不需要newsHello(0) = "Hello Tom",使用()而不是[]来访问元素In the JVM, Scala's array is implemented as a Java array. The array in the example is of
