Java Lombok | Automatically Generating the toString() Method - @ToString

`@ToString`

If you declare the @ToString annotation on a class, the toString() method is generated automatically.

package com.devkuma.tutorial.lombok;

import lombok.ToString;

import java.util.Arrays;
import java.util.List;

@ToString(exclude="ignore")
public class ToStringTutorial {

    private int id = 100;
    private String value = "devkuma";
    private List<String> list = Arrays.asList("araikuma", "kimkc");
    private double ignore = 999;

    public static void main(String[] args) {
        System.out.println(new ToStringTutorial());
    }
}

Execution result:

ToStringTutorial(id=100, value=devkuma, list=[araikuma, kimkc])

You can also specify fields to omit from the output with the exclude attribute.
If classes have mutual dependencies, calling toString() can cause an infinite loop, so it may be necessary to exclude such fields with exclude.
