私人范围

Created: November-22, 2018

范围是私有的时，只能从当前类或当前类的其他实例访问它。

package com.example {
  class FooClass {
    private val x = "foo"
    def aFoo(otherFoo: FooClass) {
      otherFoo.x // <- Accessing from another instance of the same class
    }
  }
  class BarClass {
    val f = new FooClass
    f.x // <- This will not compile
  }
}
