87. What will be the output of following Java code?

import java.util.Hashtable;

public class HashTableClass {
  int hashcode;
  HashTableClass(int hashcode) {
    this.hashcode = hashcode;
  }
  public int hashCode() {
    return hashcode;
  }
  public String toString() {
    return hashcode + " ";
  }

  public static void main(String[] args) {
    Hashtable ht = new Hashtable();
    
    ht.put(new HashTableClass(10), "Java");
    ht.put(new HashTableClass(3), "C");
    ht.put(new HashTableClass(4), "C++");
    ht.put(new HashTableClass(5), "Ruby");
    ht.put(new HashTableClass(6), "null");
    
    System.out.println(ht);
  }
}

1. {10 =Java, 3 =C, 4 =C++, 6 =null, 5 =Ruby}
2. {10 =Java, 6 =null, 5 =Ruby, 4 =C++, 3 =C}
3. {3 =C, 4 =C++, 5 =Ruby, 6 =null, 10 =Java}
4. None of these

Answer: B) {10 =Java, 6 =null, 5 =Ruby, 4 =C++, 3 =C}
