How to Perform Java Vector Difference?

Question

Hello All,
I need some help for Difference Between 2 Vectors Implementation
I have written a short program to explain what I exactly one.. BasicallY I am looking for a method that returns a Vector containing the elements of vect1 minus the elements of vect2
I tried using 2 for loops but its not possible. Is there a built in or a easier way to achieve this difference between 2 Vectors?
import java.util.Vector;
public class VectorDifference {
     static Student stud1 = new Student("Test1", 15);
     static Student stud2 = new Student("Test2", 15);
     static Student stud3 = new Student("Test3", 15);
     static Student stud4 = new Student("Test1", 15);
     static Student stud5 = new Student("Test3", 15);
     static Student stud6 = new Student("Test7", 15);
     static Vector vect1 = new Vector();
     static Vector vect2 = new Vector();
     public static void main(String[] args) {
          vect1.add(stud1);
          vect1.add(stud2);
          vect1.add(stud3);
          vect1.add(stud4);
          vect1.add(stud5);
          vect1.add(stud6);
          System.out.println("Vector 1 - Vector 2");
class Student{
     String name;
     int age;
     public int getAge() {
          return age;
     public void setAge(int age) {
          this.age = age;
     public String getName() {
          return name;
     public void setName(String name) {
          this.name = name;
     public boolean equals(Object obj){
               if(!(obj instanceof Student)){
                    return false;
               Student student2 = (Student)obj;
               if(name.equals(student2.getName()) && age == student2.getAge()){
                    return true;
               return false;
     public Student(String name, int age) {
          this.name = name;
          this.age = age;
}

Btw, vectors went out of fashion many many years ago. Use ArrayList instead.Around '98 with the introduction of ArrayList.
The OP could also consider using generics, and using a local variable instead of a field, esp a static field, when ever possible.
