Native functions #

Syntax. Many native functions/operators (e.g. over numbers or Boolean values) have the same syntax in Haskell and Java. This includes equality (==), sum (+), product (*), etc.

We highlight below a few cases where the two syntaxes differ:

meaning syntax in Haskell example syntax in Java example

inequality /= x /= 2 != x != 2

negation (NOT) not not x ! !x

disjunction (OR) || x || y || (lazy evaluation) or
| (full evaluation) x || y or
x | y

conjunction (AND) && x && y && (lazy evaluation) or
& (full evaluation) x && y or
x & y

meaning	syntax in Haskell	example	syntax in Java	example
inequality	`/=`	`x /= 2`	`!=`	`x != 2`
negation (NOT)	`not`	`not x`	`!`	`!x`
disjunction (OR)	`\|\|`	`x \|\| y`	`\|\|` (lazy evaluation) or `\|` (full evaluation)	`x \|\| y` or `x \| y`
conjunction (AND)	`&&`	`x && y`	`&&` (lazy evaluation) or `&` (full evaluation)	`x && y` or `x & y`
