The Java.util.LinkedHashSet.contains() method is used to check whether a specific element is present in the LinkedHashSet or not. So basically it is used to check if a Set contains any particular element. The contains a method of the LinkedHashSet class returns true if the specified element is found in the LinkedHashSet object.
Example:
Given List: [1, 2, 3, 4] Input : FirstSearch = 1, SecondSearch = 6 Output: True False
Syntax:
Hash_Set.contains(Object element)
Return Type: If the element found in the then it returns true, else false.
Parameters: The parameter element is of the type of LinkedHashSet. This is the element that needs to be tested if it is present in the set or not.
Example:
Java
// Checking if element exists in LinkedHashSet in Javaimport java.util.LinkedHashSet;public class LinkedHashSetContainsExample { public static void main(String[] args) { LinkedHashSet<String> lhSetColors = new LinkedHashSet<String>(); lhSetColors.add("red"); lhSetColors.add("green"); lhSetColors.add("blue"); /* * To check if the LinkedHashSet contains the * element, use the contains method. */ // this will return true as the "red" element exists System.out.println(lhSetColors.contains("red")); // this will return true as the "white" element does // not exists System.out.println(lhSetColors.contains("white")); }} |
Output
true false
