Use the "Object Assign" framework to implement the object in the Java class library
Introduction:
When developing Java applications, the attribute value of one object is often required to another object.To facilitate this function, the Java class library provides a framework called ‘Object Assign’.The ‘Object Assign’ framework allows us to copy the attribute values of one or more source objects to the target object to achieve a fast and simple object assignment operation.This article will introduce how to use the ‘Object Assign’ framework to assign object value and provide some Java code examples.
Step of the assignment of the object assignment with the "Object Assign" framework:
1. Introduce related dependencies: First of all, you need to add the dependencies of the ‘Object Assign’ framework to the construction file in the project.If you use Maven for project management, you can add the following dependencies to the pom.xml file:
<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-lang3</artifactId>
<version>3.12.0</version>
</dependency>
If you use Gradle for project management, add the following dependencies in the built.gradle file:
groovy
implementation 'org.apache.commons:commons-lang3:3.12.0'
2. Import the required class: In the Java code, you need to import ORG.APACHE.COMMONS. Lang3.ObjectItils to use the function of the ‘Object Assign’ framework:
import org.apache.commons.lang3.ObjectUtils;
3. Execute object assignment: Using the `assign ()` function of the 'Object Assign' framework can perform an object assignment operation.This function accepts two parameters: target objects and one or more source objects.The attribute value of the source object will be copied to the target object.The following is a simple example:
public class Person {
private String name;
private int age;
public Person(String name, int age) {
this.name = name;
this.age = age;
}
// Getters and setters...
}
public class Main {
public static void main(String[] args) {
Person sourcePerson = new Person("Tom", 25);
Person targetPerson = new Person("", 0);
ObjectUtils.assign(targetPerson, sourcePerson);
System.out.println("Name: " + targetPerson.getName());
System.out.println("Age: " + targetPerson.getAge());
}
}
In the above examples, we created a `Person` class that has the` name` and `age properties.In the `Main` class, we created a source object's` SourcePerson` and a target object `targetperson`.Call the attribute value of the source object to the target object.Finally, we print the attribute value of the target object.
Summarize:
The use of the "Object Assign" framework can easily implement the object value of the object in the Java library.Through the `Assign ()` function, we can copy the attribute values of one or more source objects to the target object, simplify the process of the object value of the object.In addition, the 'Object Assign' framework also provides other functions, such as default values settings and depth copy.Using this framework can improve development efficiency and code readability.
Note: When using the ‘Object Assign’ framework, make sure that the source objects and target objects have the same attribute set and attribute types are compatible.
