**1. Creating a CORBA Object**

```java
import javax.rmi.CORBA;
import org.omg.CORBA.ORB;

public class CreateCORBAObject {

    public static void main(String[] args) {
        // Create an ORB
        ORB orb = ORB.init(args, null);

        // Create a stringified IOR (Interoperable Object Reference)
        String ior = "IOR:0000000000000000000000000000000000000000000000000000000000000000";

        // Convert the IOR to a CORBA object reference
        org.omg.CORBA.Object corbaObject = orb.string_to_object(ior);
    }
}
```

**2. Invoking a CORBA Method**

```java
import javax.rmi.CORBA;
import org.omg.CORBA.ORB;
import org.omg.CORBA.Object;

public class InvokeCORBAMethod {

    public static void main(String[] args) {
        // Create an ORB
        ORB orb = ORB.init(args, null);

        // Create a stringified IOR (Interoperable Object Reference)
        String ior = "IOR:0000000000000000000000000000000000000000000000000000000000000000";

        // Convert the IOR to a CORBA object reference
        org.omg.CORBA.Object corbaObject = orb.string_to_object(ior);

        // Invoke a method on the CORBA object
        Object result = corbaObject.getClass().getMethod("methodName", new Class[] {}).invoke(corbaObject);
    }
}
```

**3. Passing Parameters to a CORBA Method**

```java
import javax.rmi.CORBA;
import org.omg.CORBA.ORB;
import org.omg.CORBA.Object;

public class PassParametersToCORBAMethod {

    public static void main(String[] args) {
        // Create an ORB
        ORB orb = ORB.init(args, null);

        // Create a stringified IOR (Interoperable Object Reference)
        String ior = "IOR:0000000000000000000000000000000000000000000000000000000000000000";

        // Convert the IOR to a CORBA object reference
        org.omg.CORBA.Object corbaObject = orb.string_to_object(ior);

        // Create an array of parameters to pass to the method
        Object[] parameters = new Object[] { "parameter1", 2 };

        // Invoke a method on the CORBA object passing the parameters
        Object result = corbaObject.getClass().getMethod("methodName", new Class[] { String.class, int.class }).invoke(corbaObject, parameters);
    }
}
```

**4. Returning a Value from a CORBA Method**

```java
import javax.rmi.CORBA;
import org.omg.CORBA.ORB;
import org.omg.CORBA.Object;

public class ReturnValueFromCORBAMethod {

    public static void main(String[] args) {
        // Create an ORB
        ORB orb = ORB.init(args, null);

        // Create a stringified IOR (Interoperable Object Reference)
        String ior = "IOR:0000000000000000000000000000000000000000000000000000000000000000";

        // Convert the IOR to a CORBA object reference
        org.omg.CORBA.Object corbaObject = orb.string_to_object(ior);

        // Invoke a method on the CORBA object
        Object result = corbaObject.getClass().getMethod("methodName", new Class[] {}).invoke(corbaObject);

        // Cast the result to the expected return type
        String returnedValue = (String) result;
    }
}
```

**5. Handling Exceptions in CORBA**

```java
import javax.rmi.CORBA;
import org.omg.CORBA.ORB;
import org.omg.CORBA.Object;

public class HandleExceptionsInCORBA {

    public static void main(String[] args) {
        // Create an ORB
        ORB orb = ORB.init(args, null);

        try {
            // Create a stringified IOR (Interoperable Object Reference)
            String ior = "IOR:0000000000000000000000000000000000000000000000000000000000000000";

            // Convert the IOR to a CORBA object reference
            org.omg.CORBA.Object corbaObject = orb.string_to_object(ior);

            // Invoke a method on the CORBA object
            corbaObject.getClass().getMethod("methodName", new Class[] {}).invoke(corbaObject);
        } catch (Exception e) {
            // Handle the exception
        }
    }
}
```

**6. Creating a CORBA Value Type**

```java
import javax.rmi.CORBA.ValueHandler;
import org.omg.CORBA.ORB;
import org.omg.CORBA.StructMember;
import org.omg.CORBA.TypeCode;

public class CreateCORBAValueType {

    public static void main(String[] args) {
        // Create an ORB
        ORB orb = ORB.init(args, null);

        // Create a ValueHandler for the value type
        ValueHandler valueHandler = new ValueHandler() {

            @Override
            public Object extract(TypeCode tc, byte[] data) {
                // Extract the value from the data
                return null;
            }

            @Override
            public byte[] insert(TypeCode tc, Object value) {
                // Insert the value into the data
                return null;
            }
        };

        // Create the value type definition
        TypeCode typeCode = orb.create_value_type("MyValueType", "MyValueType", new StructMember[] {});

        // Register the value type with the ORB
        typeCode.register_value_handler(valueHandler);
    }
}
```

**7. Using a CORBA Value Type**

```java
import javax.rmi.CORBA.ValueHandler;
import org.omg.CORBA.ORB;
import org.omg.CORBA.StructMember;
import org.omg.CORBA.TypeCode;

public class UseCORBAValueType {

    public static void main(String[] args) {
        // Create an ORB
        ORB orb = ORB.init(args, null);

        // Create a stringified IOR (Interoperable Object Reference) for a CORBA object that implements the value type
        String ior = "IOR:0000000000000000000000000000000000000000000000000000000000000000";

        // Convert the IOR to a CORBA object reference
        org.omg.CORBA.Object corbaObject = orb.string_to_object(ior);

        // Get the type code for the value type
        TypeCode typeCode = corbaObject.getClass().getMethod("getTypeCode", new Class[] {}).invoke(corbaObject);

        // Get the value handler for the value type
        ValueHandler valueHandler = typeCode.get_value_handler();

        // Create a value of the value type
        Object value = valueHandler.extract(typeCode, null);

        // Set the value on the CORBA object
        corbaObject.getClass().getMethod("setValue", new Class[] { typeCode.type() }).invoke(corbaObject, new Object[] { value });
    }
}
```

**8. Creating a CORBA Interface**

```java
import org.omg.CORBA.IDLType;
import org.omg.CORBA.ORB;

public class CreateCORBAInterface {

    public static void main(String[] args) {
        // Create an ORB
        ORB orb = ORB.init(args, null);

        // Create an IDLType for the interface
        IDLType idlType = orb.get_interface_idl_type("MyInterface");

        // Create the interface definition
        String interfaceDefinition = idlType.get_definition();
    }
}
```

**9. Using a CORBA Interface**

```java
import org.omg.CORBA.IDLType;
import org.omg.CORBA.ORB;

public class UseCORBAInterface {

    public static void main(String[] args) {
        // Create an ORB
        ORB orb = ORB.init(args, null);

        // Create an IDLType for the interface
        IDLType idlType = orb.get_interface_idl_type("MyInterface");

        // Create an instance of the interface
        Object interfaceInstance = orb.create_instance(idlType);
    }
}
```

**10. Creating a CORBA Server**

```java
import javax.rmi.CORBA.Tie;
import org.omg.CORBA.ORB;

public class CreateCORBA

```
