What does it mean to set a mutable object to 'val'?
scala
Solution
It's still a `val`. The reference can't be changed, but the object referred to can have its internal state mutated.
`val` means you can't do this reassignment:
val st = new Pojo()
st = new Pojo() // invalid!
For this you need a `var`:
var st = new Pojo()
st = new Pojo() // ok
Problem
I'm setting a java Pojo instance variable to 'val' & changing its state after it's initialized. Will this cause any issues since its really a 'var' ? ``` val st = new Pojo(); st.setInt(0); ```
