以下是在 Java 中从 Quartet 类实现 Quintet 类的示例 −
示例
import org.javatuples.Quartet;
import org.javatuples.Quintet;
public class MyDemo {
public static void main(String[] args) {
Quartet<String, String, String, String>quartet = new Quartet<String, String, String, String>(
"Table", "Chair", "Pen", "Paper");
System.out.println("Quartet elements = " + quartet);
Quintet<String, String, String, String, String>quintet = quartet.add("Notebook");
System.out.println("Quintet (implemented from Quartet) elements = " + quintet);
}
}
输出
Quartet elements = [Table, Chair, Pen, Paper] Quintet (implemented from Quartet) elements = [Table, Chair, Pen, Paper, Notebook]
现在让我们看另一个例子，在 Java 中从 Quartet 类实现 Quintet 类 −
示例
import org.javatuples.Quartet;
import org.javatuples.Quintet;
public class MyDemo {
public static void main(String[] args) {
Quartet<String, String, String, String>quartet = new Quartet<String, String, String, String>(
"Notebook", "Chair", "Pen", "Table");
System.out.println("Quartet elements = " + quartet);
Quintet<String, String, String, String, String>quintet = quartet.addAt0("Board");
System.out.println("Quintet (implemented from Quartet) elements = " + quintet);
}
}
输出
Quartet elements = [Notebook, Chair, Pen, Table] Quintet (implemented from Quartet) elements = [Board, Notebook, Chair, Pen, Table]
