How to Import Classes in Java
- 1). Identify the name of the package that contains the Java class(es) you need. Java packages are similar to libraries in other programming languages. A good resource for finding which package contains a given class in the standard Java Platform is Oracle's "API Specification" Web document (see Resources).
- 2). Import one class at a time by including a fully-specified "import" statement at the beginning of your Java program. For example, "import java.net.InetAddress;" imports only the InetAddress class.
- 3). Import a family of related classes by including a single wildcard "import" statement at the beginning of your code. For example, "import java.net.*;" imports all classes that share the "java.net" prefix, such as InetAddress, Proxy and URL.
