JDBC stands for Java Database Connectivity, which is an API that allows us to build applications that can access and manipulate with many different types of databases. In this tutorial, I will talk to you about the basic knowledge of JDBC. First, I will create… Read More
To migrate any file in Java, in Java 6 or older Java versions, we can use the renameTo() method located in the File object to do this:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 |
package com.huongdanjava.javaexample; import java.io.File; public class MoveFile { public static void main(String[] args) { File source = new File("F://source.txt"); File dest = new File("E://dest.txt"); if (source.renameTo(dest)) { System.out.println("Move file " + source.getAbsolutePath() + " to " + dest.getAbsolutePath() + " success."); } } } |
Result:
|
1 |
Move file F:\source.txt to E:\dest.txt success |
From Java 7 onwards, we have another way to move a file, which is to… Read More
The CXF component in the Mule ESB uses the Apache CXF library to help us create a SOAP Web Service or consume from a SOAP Web Service. In this tutorial, I will show you how to use CXF component in Mule ESB to create a… Read More
In this tutorial, we will cover how to copy any file in Java. If you consider Java 6 or earlier, Java does not have an object or method that supports us copying a file, only creating or deleting a file. So if you are working… Read More
Before going into the JPA tutorials, I think I need to clarify the differences between JPA and Hibernate because I see if most of you did not understand thoroughly, will not distinguish the difference between them. JPA stands for Java Persistence API, which is a… Read More
Anyone who wants to learn about JPA needs to know about the concept of Object Relational Mapping. So what is it actually? Suppose, you are working on an application and your application uses a table named users in the database. The structure of this table… Read More
We already know how to get an object from the Spring container using the getBean() method but sometimes we have the opposite need. That is, we want to use the Spring container in our object to have access to other objects in its container. Is… Read More
Even though creating a file in Java is easy, deleting a file is easier. In this tutorial, I will guide you how to delete a file in Java. The File object, which is the main file management object since Java version 6 and earlier, cannot be… Read More
Creating files in Java is a basic operation, everyone must know. So, in this tutorial, I just synthesized the ways that we can create a file in Java. Maybe it is useful for beginners of Java programming. First, I have to mention the File object.… Read More
In my tutorials about the Spring framework, I often use the object of the ApplicationContext interface as a Spring container to call the object that I need to retrieve. For example, in the previous tutorial:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 |
package com.huongdanjava.springbeanautowiring; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; public class Application { public static void main(String[] args) { ApplicationContext context = new ClassPathXmlApplicationContext("spring.xml"); Room room = (Room) context.getBean("room"); if (room.getTable() != null) { System.out.println(room.getTable().toString()); } } } |
But in fact, Spring also provides us with another… Read More
