Explain why generics make more sense as a feature in statically typed languages than in dynamically typed languages.
Fully parenthesize the following expression to illustrate the order in which Smalltalk will evaluate it.
2 + 3 factorial * 4 gcd: 12 - 4
Give Smalltalk code for defining a new instance method deductPenalty in our Account class, which should deduct 10 from the balance if the current balance is below 500. Your code should use the withdraw: method already defined for the Account class.
Give and describe an example of how the Composite pattern shows up in the AWT or Swing user interface libraries of Java.
(( 2 + ( 3 factorial )) * 4 ) gcd: ( 12 - 4 )
deductPenalty balance < 500 ifTrue: [ self withdraw: 10 ]
