type of data:

C#：String与StringBuilder

Java：String与StringBuffer

The first string is not used in the first letter should be capitalized.

The second is not used to have written int Integer, though you can define int i = 0, but for other generic usage must ArrayList <Integer>.

Comparative common collections:

C# ：HashTable List<T> Dictionary<T,K>

Java：HashTable List（包括：ArrayList<T>，LinkedList<T>) Map<T,K>（包括：HashMap<T,K>，SortedMap<T,K>）

Set (including: HashSet <T>, SoredSet <T>)

Set: can not contain duplicate elements;

List: may contain duplicate elements.

Or with a lot of class collections, the comparison I have a big head almost, and finally find such a simple relationship.

Stack and Queue:

C# ：Stack<T> Queue<T>

Java：Stack<T> Queue（包括四个：LinkedBlockingQueue<T>、ArrayBlockingQueue<T>、PriorityBlockingQueue<T>、DelayQueue<T>）

Stack consistent usage, usage and Queue Name substantially days and the difference, the answer in detail below.

Java Queue C # method names and different:

Java Queue related methods:

add increased one yuan cable if the queue is full, an exception is thrown a IIIegaISlabEepeplian
Remove removes and returns the element head of the queue if the queue is empty, throw an exception NoSuchElementException
element returns the element head of the queue if the queue is empty, an exception is thrown a NoSuchElementException
offer add an element and returns true if the queue is full, false returns
poll removed and returned to ask the head of the queue element if the queue is empty, null is returned
peek returns the element head of the queue if the queue is empty , null is returned
put add an element if the queue is full, then blocked

take to remove and return the head of the queue element if the queue is empty, blocked

Iterator syntax:

# C: the foreach (Object in objList O) interface name} {iterative implementation of: the IEnumerable

Java: the foreach (Object O: objList) {} interface name iterative implementation of: the Iterable

variable parameter:

# C: void the Sum (params int [] List)} to {params keywords

The Java: void SUM (int ... List) {} with "..." three points for the keyword

Enumeration, Java enum can play out the pattern:

C #: enum can only set the constant value

Java: In addition to setting the constant value and the same C #, Java still retains the basic functions of a special class, allowing players to play their own; and C # to do special restrictions.

C # and Java string and turn enumerate enumeration traversal difference:

C # conversion codes:

   public class the Test
    {
         protected void Method, ()
        {
            A = A (A) that Enum.Parse ( typeof (A), " B " ); // Enumeration conversion

foreach (string enumName in Enum.GetNames(typeof(A)))

{

// enumeration traversal

}

        }

        public enum A
        {
            b,
            c
        }
    }

Java conversion codes:

    public class Test
    {
         protected void method()
        {
            A a = A.valueOf("b");

for (A a : A.values())

{

// enumeration traversal

}

        }

         public enum A
        {
            b,
            c
        }
}

Basically the same, today to see the content, basically so much, so I wrote here, such a point of content, relatively light finish, it took several hours, really sad reminders.
