回答1:

Java 8

Java 8 will use TLS 1.2 by default

https://blogs.oracle.com/java-platform-group/jdk-8-will-use-tls-12-as-default

So for Java 8 all you need to do is the following.

import javax.net.ssl.*;
import java.net.URL;

URL url = new URL("https://www.google.com");
HttpsURLConnection connection = (HttpsURLConnection) url.openConnection();

Java 7

Java 7 needs to be set manually

import java.security.*;
import javax.net.ssl.*;
import java.net.URL;


URL url = new URL("https://www.google.com");

SSLContext ssl = SSLContext.getInstance("TLSv1.2"); 
ssl.init(null, null, new SecureRandom());

HttpsURLConnection connection = (HttpsURLConnection) url.openConnection();
connection.setSSLSocketFactory(ssl.getSocketFactory());
