Because Pnuts compiles to Java byte codes, these classes can be used by Java just like any other class. A class written in Pnuts can even later be replaced by a class written in Java with no other code changes. Pnuts syntax can look very similar to Java. The following is a code sample written in Java that is also a valid Pnuts script:
Array, a sequence of elements of the same type stored contiguously in memory; Record (also called a structure or struct), a collection of fields . Product type (also called a tuple), a record in which the fields are not named
The compile-time check guarantees that the resulting code uses the correct type. [7] Because of type erasure, type parameters cannot be determined at run-time. [6] For example, when an ArrayList is examined at runtime, there is no general way to determine whether, before type erasure, it was an ArrayList<Integer> or an ArrayList<Float>.
However, new ArrayList<Generic<?>>() is allowed, because the wildcard is not a parameter to the instantiated type ArrayList. The same holds for new ArrayList<List<?>>() . In an array creation expression, the component type of the array must be reifiable as defined by the Java Language Specification, Section 4.7.
A linked list is a sequence of nodes that contain two fields: data (an integer value here as an example) and a link to the next node. The last node is linked to a terminator used to signify the end of the list. In computer science, a linked list is a linear collection of data elements whose order is not given by their physical placement in memory.
For example, a content-based view shows ArrayList and LinkedList in an identical way, as a list of elements. Structural views show the internal structure of trees , linked lists , hash tables , etc. Structural views of linked data structures display local variable nodes and their relation to the main structure.
