Hi,

The Cloneable interface defines no members. It is used to indicate that a class allows a bitwise copy of an object (that is, a clone) to be made. If you try to call clone( ) on a class that does not implement Cloneable, a CloneNotSupportedException is thrown. When a clone is made, the constructor for the object being cloned is not called. A clone is simply an exact copy of the original.

Thanks.

The Example of cloneable interface-

class TestCloneDemo implements Cloneable {
    int a;
    double b;

    // This method calls Object's clone().
    TestCloneDemo cloneTest() {
        try {
            // call clone in Object.
            return (TestCloneDemo) super.clone();
        } catch (CloneNotSupportedException e) {
            System.out.println("Cloning not allowed.");
            return this;
        }
    }
}

public class CloneDemo {
    public static void main(String args[]) {
        TestCloneDemo x1 = new TestCloneDemo();
        TestCloneDemo x2;
        x1.a = 15;
        x1.b = 35.05;
        x2 = x1.cloneTest(); // clone x1
        System.out.println("x1: " + x1.a + " " + x1.b);
        System.out.println("x2: " + x2.a + " " + x2.b);
    }
}
