Console Table Builder framework based on the Java class library

Console Table Builder framework based on the Java class library When writing an interactive Java console application, we often need to display the data table to better present and organize information.In order to simplify the creation process of the data table, a commonly used solution is to use the existing Java library to build a Console Table Builder framework.This article will introduce the principle of this framework in detail and provide relevant programming code and configuration examples. The principle of the Console Table Builder framework is based on the Java class library, which aims to provide a simple and flexible way to create and display the data table.It mainly depends on Java's text output function, such as the characteristics of the Java IO stream and string formatting.By appropriate configuration, we can display data in a readability and good format in the console. Below is a simple example code that demonstrates how to use the Console Table Builder framework to create and display a simple data table: import java.util.ArrayList; import java.util.List; public class ConsoleTableExample { public static void main(String[] args) { // Create a table builder object ConsoleTableBuilder tableBuilder = new ConsoleTableBuilder(); // Set the name of the form tablebuilder.addrow ("name", "age", "gender"); // Add data line tablebuilder.addrow ("Zhang San", "25", "Male"); tablebuilder.addrow ("Li Si", "30", "Male"); tablebuilder.addrow ("Wang Wu", "28", "Female"); // Print form to the console tableBuilder.print(); } } In the above code, we first instantiated a ConsoletableBuilder object, and then used the adDRow () method to add a header and data row.Finally call the print () method to print the form to the console. In addition to the simple tables in the above examples, the Console Table Builder framework also supports more configuration options, such as alignment methods, column width, table style, etc.The corresponding configuration can be performed through the following code: // Set up a columns tableBuilder.setAlign(ConsoleTable.Align.LEFT); // Set the column width tableBuilder.setColWidth(20); // Set table style tableBuilder.setStyle(ConsoleTable.Style.BOLD); // Add border tableBuilder.setShowVerticalLines(true); tableBuilder.setShowHorizontalLines(true); Through the above code example, we can perform a more fine -grained table configuration to meet actual needs. In summary, the Console Table Builder framework is a Java -type library -based tool. It provides a simple and flexible way to create and display the data table in the console through appropriate configuration.Developers can present data by using the Console Table Builder framework to present data in a more convenient and elegant way to improve the user experience.
