Returns the minimum value in a generic sequence according to a specified key selector function and key comparer. Filters the elements of an IEnumerable based on a specified type. The index of each source element is used in the projected form of that element.
The index of each source element is used in the intermediate projected form of that element. Determines whether two sequences are equal by comparing the elements by using the default equality comparer for their type. Returns the only element of a sequence, and throws an exception if there is not exactly one element in the sequence.
Returns the only element of a sequence that satisfies a specified condition, and throws an exception if more than one such element exists. Returns the only element of a sequence, or a default value if the sequence is empty; this method throws an exception if there is more than one element in the sequence. Returns the only element of a sequence, or a specified default value if the sequence is empty; this method throws an exception if there is more than one element in the sequence. Returns the only element of a sequence that satisfies a specified condition or a default value if no such element exists; this method throws an exception if more than one element satisfies the condition.
Returns the only element of a sequence that satisfies a specified condition, or a specified default value if no such element exists; this method throws an exception if more than one element satisfies the condition. Returns a new enumerable collection that contains the elements from source with the last count elements of the source collection omitted.
Bypasses elements in a sequence as long as a specified condition is true and then returns the remaining elements. The element's index is used in the logic of the predicate function.

Ask Question. Asked 7 years, 10 months ago. Active 4 months ago. Viewed 64k times. I am new to java, i know set is not allowed duplicate value but i don't know why set is not allowed duplicate value , Actually i am doing practically, Declared one set and add duplicate value but no kind of error is occurring, no compile time error, no run time. Improve this question. Vala J.

I've seen a number of clearly-wrong guesses, where the editor basically ended up inadvertently vandalizing the question. Happens all the time.

Andres Andres Set Oracle Documentation A collection that contains no duplicate elements. Add Method According to the documentation of the interface, if the element does not exist it is added. Menelaos Menelaos There can be two possibilities : if map. Hope this will help in understanding clearly.

Bulk operations are particularly well suited to Set s; when applied, they perform standard set-algebraic operations. Suppose s1 and s2 are sets. Here's what bulk operations do:. To calculate the union, intersection, or set difference of two sets nondestructively without modifying either set , the caller must copy one set before calling the appropriate bulk operation. The following are the resulting idioms.
The implementation type of the result Set in the preceding idioms is HashSet , which is, as already mentioned, the best all-around Set implementation in the Java platform.
However, any general-purpose Set implementation could be substituted. Let's revisit the FindDups program. Suppose you want to know which words in the argument list occur only once and which occur more than once, but you do not want any duplicates printed out repeatedly.
The words that occur only once are the set difference of these two sets, which we know how to compute. Here's how the resulting program looks. When run with the same argument list used earlier i came i saw i left , the program yields the following output. If two objects have the same hash code, they may or may not be equal. How set avoid duplicates in java Here we will see how set avoid duplicates in java or why set does not allow duplicates in java.
Here we will see how set avoids duplicates in java with example First create the Implementation class object which is shown below in step 1 Implementation class constructor internally create HashMap object which is shown below in step 2 When we add element using add method, Implementation class internally uses put method of HashMap class which is shown below in step 3 and 4 put internally uses the putVal method which uses the hashCode of Object to determine whether element is already present or not which is shown in step 5.
