When calling REST APIs from Java, which class can be used for HTTPS connections?

• A. java.net.HttpURLConnection
• B. javax.net.ssl.HttpsURLConnection
• C. java.http.HttpConnector
• D. javax.net.HttpURLConnection

Answer: (B)

In Java, when making HTTPS (Hypertext Transfer Protocol Secure) connections specifically, the appropriate class to use is HttpsURLConnection from the javax.net.ssl package. This class extends HttpURLConnection and is specifically designed to handle secure HTTP connections. It provides functionalities that ensure the connection is secured using SSL/TLS protocols, which is essential for ensuring the integrity and security of the data transmitted over the network. Using HttpsURLConnection allows developers to leverage features crucial for secure communications, such as setting SSL socket factories and validating certificates. This makes it particularly suitable for REST API calls that require a secure transport layer. The class provides methods to configure and manage SSL contexts, which are central to secure communications in Java. Other options either refer to general classes not specifically designed for HTTPS or do not exist in the standard Java libraries. For instance, java.net.HttpURLConnection would only offer functionality for non-secure connections (HTTP), which could lead to vulnerabilities. Additionally, java.http.HttpConnector is not a standard class found within the Java SDK, and javax.net.HttpURLConnection does not exist; the correct class is solely HttpsURLConnection for secure HTTP connections.
