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
