Equals Method on Cloned objects

As we discussed during the class, in case of custom or user defined class, creation of equals method is must. I also created it from the IDE itself. 

Source -> Generate hashCode and equals method option for all fields.

Even if this methods exist somewhere in the hierarchy, any parent class has, that will also work just that the equals method implementation should be there.

In the class itself/anywhere in the parent abstract class or anywhere in the base framework class if we are working on a framework, if equals method implementation is there, this concept will work.

public class Test implements Cloneable{
	int attribute1;
	String attribute2;

	Test(int attribute1, String attribute2) {
		this.attribute1 = attribute1;
		this.attribute2 = attribute2;
	}

	public static void main(String[] args) throws CloneNotSupportedException {
		Test obj1 = new Test(1, "Aditya");

		Test obj2 = (Test) obj1.clone();
		System.out.println("First attribute value = " + obj1.attribute1);
		System.out.println("Second attribute value = " + obj1.attribute2);
		System.out.println("Clone Successfull.....");
		System.out.println("First attribute value = " + obj2.attribute1);
		System.out.println("Second attribute value = " + obj2.attribute2);

		if (obj1.equals(obj2)) {
			System.out.println("The objects are equal");
		} else {
			System.out.println("Objects are not equal");
		}

	}

	@Override
	public int hashCode() {
		final int prime = 31;
		int result = 1;
		result = prime * result + attribute1;
		result = prime * result + ((attribute2 == null) ? 0 : attribute2.hashCode());
		return result;
	}

	@Override
	public boolean equals(Object obj) {
		if (this == obj)
			return true;
		if (obj == null)
			return false;
		if (getClass() != obj.getClass())
			return false;
		Test other = (Test) obj;
		if (attribute1 != other.attribute1)
			return false;
		if (attribute2 == null) {
			if (other.attribute2 != null)
				return false;
		} else if (!attribute2.equals(other.attribute2))
			return false;
		return true;
	}
