Program Plan Intro

Implementation of hash set

Program plan:

  • In a file “HashSet.java”, import necessary package, and create a class “HashSet”,
    • Declare the array of “Node” type.
    • Declare the necessary variable.
    • Define the constructor to create a hash table.
    • Create an array and set the current size to “0”.
    • Define the method “contains()”,
      • Assign the hash code.
      • Check whether the value is less than “0”,
        • If it is true, assign the negative value.
      • Update the hash value.
      • Assign the current node value.
      • Execute loop till array becomes null,
        • Check the condition,
          • Return true.
            • Assign the current value.
    • Define the method “add()” to add the element to the set,
      • Get the hash code.
      • Check whether the value is less than “0”,
        • If it is true, assign the negative value.
      • Update the hash code.
      • Assign the hash code value to the current node.
      • Execute a loop,
        • Check the condition,
          • Return false.
            • Assign the next value to the value in the current node.
      • Create a new node.
      • Assign the value to new node value.
      • Assign the value to the next node.
      • Assign the new node value to the bucket.
      • Increment the size.
      • Return true.
    • Define the method “remove()” to remove the object from the set,
      • Get the hash code.
      • Check whether the value is less than “0”,
        • If it is true, assign the negative value.
      • Update the hash code.
      • Assign the hash code value to the current node.
      • Set null to the previous node.
      • Execute a loop,
        • Check the condition,
          • Check whether the previous node contains null value,
            • If it is true, assign the next node value to the bucket.
          • Otherwise,
            • Assign the next of the current node value to the next of the previous node value.
          • Decrement the size.
          • Return true.
              • Assign the current node value to the previous node value.
              • Assign the next of the current node value to the current node.
      • Return false.
    • Define the method “iterator ()” to return an iterator that traverse the set elements,
      • Return the object of “HashSetIterator”.
    • Define the method “size ()” to return the size of the set.
    • Create a class “Node”,
      • Declare the object for “Object”.
      • Declare the object of “Node”.
    • Create a class “HashSetIterator”,
      • Declare the necessary variables.
      • Define the constructor to create a hash set that point to the first element of the hash set.
      • Define the method “asNext()”,
        • Check whether the next node contains null,
          • If it is true, returns true.
              • Check whether the current node and the next of the current node is not null,
                • Assign the next of the current node value to the next node.
                • Return true.
              • Execute a loop,
                • Check whether the bucket contains not null value,
                  • If it is true, assign the bucket value to the next node.
                  • Assign the value to the bucket.
                  • Returns true.
              • Returns false.
      • Define the method “next()”,
        • Check the condition,
          • Throw an exception “NoSuchElementException”.
              • Assign the next node value to the current node value.
              • Assign the null value to the next node.
              • Return the current node value.
      • Define the method “remove()”,
        • Throw an exception “UnsupportedOperationException”.
  • In a file “HashSetTest.java”, import necessary package, and create a class “HashSetTest”,
    • Define the “main()” method,
      • Create an object fro “HashSet”.
      • Add the element “Tom” to the set.
      • Add the element “Jerry” to the set.
      • Add the element “Nick” to the set.
      • Add the element “James” to the set.
      • Add the element “Johny” to the set.
      • Add the element “David” to the set.
      • Add the element “Else” to the set.
      • Add the element “Joy” to the set.
      • Add the element “Francis” to the set.
      • Add the element “Jenny” to the set.
      • Add the element “Casendra” to the set.
      • Add the element “Juliet” to the set.
      • Remove the element “Juliet” from the set.
      • Remove the element “Jaen” from the set.
      • Create Iterator.
      • Execute a loop,
        • Print the next element in the set.
