Console Table Builder Framework Implementation of Custom Form Construction of Java Library
Console Table Builder Framework Implementation of Custom Form Construction of Java Library
Overview:
During the development of Java, sometimes we need to display data in the form of a form, which is very helpful for debugging, output results, or only to better visual data.However, Java's native form output method is relatively cumbersome, and it is necessary to manually process the details of data formats, alignment, borders and other details.In order to simplify the construction process of the table, we can use the Console Table Builder framework to construct the form.
Console Table Builder is an open source Java library, which aims to provide Java developers with a fast, flexible and easy -to -use table construction method.This framework allows us to define the structure of the form, the style of the cell, the style of the cell, etc., so that the construction process of the form is more concise and easy to read, and supports rich custom functions.
Example code and configuration:
The following code and configuration will show how to use the Console Table Builder framework to create a table containing student information.First, we need to add the library of Console Table Builder to our project.For example, use Maven dependence:
<dependency>
<groupId>com.github.vincent-paing</groupId>
<artifactId>console-table-builder</artifactId>
<version>2.0.0</version>
</dependency>
Next, we will define a Student class to represent student information:
public class Student {
private String name;
private int age;
private String gender;
// Construct function, getters, setters, etc.
// Rewrite it to display student information in the table
@Override
public String toString() {
return "Student{" +
"name='" + name + '\'' +
", age=" + age +
", gender='" + gender + '\'' +
'}';
}
}
Then we can use Console Table Builder to build our table.The following code demonstrates how to create a form containing student information:
import com.github.vincentrussell.tablebuilder.Table;
import com.github.vincentrussell.tablebuilder.style.Style;
import java.util.Arrays;
import java.util.List;
public class Example {
public static void main(String[] args) {
// Define the name of the form
List <strong> headers = arrays.aslist ("name", "age", "gender");
// Create a list containing student information
List<Student> students = Arrays.asList(
New Student ("Zhang San", 20, "Men"),
New Student ("Li Si", 22, "Female"),
New Student ("Wang Wu", 21, "Male")
);
// Create a new form
Table.Builder tableBuilder = new Table.Builder()
.withheaders (headers) // Set the list name
.addrowsePator (true) // Add row separators
.withstyle (style-> style.setbordrtop (true)) // Set the top border on the top of the table
.withstyle (style-> style.setBordBORDERTM (true)) // Set the bottom border frame frame frame
.withRows(students, (row, student, rowIndex) -> row
.adddata (Student.getName ()) // Add student name data to the form
.adddata (Student.getage ()) // Add student age data to the form
.adddata (Student.getGender ()) // Add student gender data to the table
);
// Print form output
System.out.println(tableBuilder.build().getTableString());
}
}
Through the above code, we can see a beautiful table in the console, which contains the student's name, age, and gender information.The Console Table Builder framework makes the construction process of the table simple, and through the flexible configuration options and callback functions to achieve personalized customization of table styles and content.
