An iterator in Java provides the means to access elements of a collection one-by-one in a sequential, unidirectional and non-repeatable manner. This is useful in cases when the size of the collection is not known beforehand or when the collection does not expose suitable methods to access a ...
The remove() when called, eliminates the element that was returned by the call to next(). The remove method was added to java iterator because the iterator knows the exact position of all the elements in the collection. It is a lot easier to remove an object from the collection if you ...
By using this iterator object, you can access each element in the collection, one element at a time. importjava.util.Iterator;importjava.util.LinkedList;//fromjava2s.compublicclassMain{publicstaticvoidmain(String args[]) { LinkedList<String> ll =newLinkedList<String>(); ll.add("A"); ll....

Implement Iterator rather than Enumeration. Reduce the total number of break and continue statements in this loop to use at most one. Use classes from theJavaAPIinstead of Sun classes. Remove this use of "encode"; it is deprecated.

Convert JSON to XML; extract interfaces from Java source code, etc. This section takes the implementation of four arithmetic calculators as an example to introduce the simple application of Antlr4 and pave the way for the later implementation of ANTLR4 to parse SQL. In fact, supporting digital...
