Why are enums used?

An enumeration, or Enum , is a symbolic name for a set of values. Enumerations are treated as data types, and you can use them to create sets of constants for use with variables and properties.

Why do we need enum?

Enums are lists of constants. When you need a predefined list of values which do represent some kind of numeric or textual data, you should use an enum. You should always use enums when a variable (especially a method parameter) can only take one out of a small set of possible values.

  • Step 1: the syntax tree as a class hierarchy.

  • Discriminated type unions vs. normal type unions.

How do I convert a string to a number?

In Java, we can use Integer.valueOf() and Integer.parseInt() to convert a string to an integer.

  1. Use Integer.parseInt() to Convert a String to an Integer. This method returns the string as a primitive type int.
  2. Use Integer.valueOf() to Convert a String to an Integer. This method returns the string as an integer object.
