Expand the example code to have some simple functionality and then write unit tests that integrate with Guice for their behavior. import com.google.inject.AbstractModule; public class BillingModule extends AbstractModule { @Override protected void configure() { /* * This tells Guice that whenever it sees a dependency on a TransactionLog, * it should satisfy the dependency using a DatabaseTransactionLog. */ bind(TransactionLog.class).to(DatabaseTransactionLog.class); /* * Similarly, this binding tells Guice that when CreditCardProcessor is used in * a dependency, that should be satisfied with a PaypalCreditCardProcessor. */ bind(CreditCardProcessor.class).to(PaypalCreditCardProcessor.class); } }
OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
Expand the example code to have some simple functionality and then write unit tests that integrate with Guice for their behavior.
import com.google.inject.AbstractModule;
public class BillingModule extends AbstractModule {
@Override
protected void configure() {
/*
* This tells Guice that whenever it sees a dependency on a TransactionLog,
* it should satisfy the dependency using a DatabaseTransactionLog.
*/
bind(TransactionLog.class).to(DatabaseTransactionLog.class);
/*
* Similarly, this binding tells Guice that when CreditCardProcessor is used in
* a dependency, that should be satisfied with a PaypalCreditCardProcessor.
*/
bind(CreditCardProcessor.class).to(PaypalCreditCardProcessor.class);
}
}
