+public abstract class Prototype {
+    abstract Prototype myClone();
+}
+```
+
+```java
+public class ConcretePrototype extends Prototype {
+
+    private String filed;
+
+    public ConcretePrototype(String filed) {
+        this.filed = filed;
+    }
+
+    @Override
+    Prototype myClone() {
+        return new ConcretePrototype(filed);
+    }
+
+    @Override
+    public String toString() {
+        return filed;
+    }
+}
+```
+
+```java
+public class Client {
+    public static void main(String[] args) {
+        Prototype prototype = new ConcretePrototype("abc");
+        Prototype clone = prototype.myClone();
+        System.out.println(clone.toString());
+    }
+}
