There are two ways to format Java JSON

Gson creates the classes for the demo

class Person{

    private String name;
    private int age;
    public Person() {}
    //java fhadmin.cn
    public Person(String name, int age) {
        this.name = name;
        this.age = age;
    }
    Override
    public String toString() {
        return "Person{" +
                "name='" + name + '\'' +
                ", age=" + age +
                '}';
    }
    Override
    public boolean equals(Object o) {
        if (this == o) return true;
        if (o == null || getClass() != o.getClass()) return false;
        Person person = (Person) o;
        return age == person.age &&
                Objects.equals(name, person.name);
    }
    Override
    public int hashCode() {
        return Objects.hash(name, age);
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public int getAge() {
        return age;
    }
    public void setAge(int age) {
        this.age = age;
    }
}
