I am new to Scala, trying to understand the syntactic behaviors of Scala. I will be really appreciated if anybody help me. Thanks
With Anonymous Object: Here in this scenario if I want to print the value of res
inside the main
function body then what logic I need to apply?
package oops
object AnonymousObject
{
def main(args:Array[String]):Unit =
{
new student().detail(5,9) // Line 1
}
}
class student
{
def detail(x:Int, y:Int):Int =
{
val res = x*y
println(res)
}
}
Without Anonymous Object:
For more information, in this scenario given below, there has no problem to achieve it because of var s
class Student
{
var id:Int = 0; // All fields must be initialized
var name:String = null;
}
object MainObject
{
def main(args:Array[String])
{
var s = new Student() // Creating an object
println(s.id+" "+s.name);
}
}
An object which has no reference name. So simply you can print like this way inside the main
object AnonymousObject
{
def main(args:Array[String]):Unit =
{
val res = new student().detail(5,9)
println(res)
}
}
class student
{
def detail(x:Int, y:Int):Int =
{
x*y
}
}
Output: 45
