Output not matching requirements

Question about the task

We don't need templates

Resolved

For some reason the output is not printing the person's sex.

If you're tired of the typical string format returned by the toString method, then today is your lucky day.

Your task is to create your own string formatting style in the overridden toString method of the Person class, using two specific classes from the org.apache.commons.lang3.builder package of the Apache Commons library.

To achieve this, in the toString method of the Person class, you need to:

Using one of the methods from the StandardToStringStyle class, disable the use of the class name.
Using one of the methods from the StandardToStringStyle class, disable the use of the class's hash code.
Using one of the methods from the StandardToStringStyle class, set the beginning of the string as "This person's ".
Using one of the methods from the StandardToStringStyle class, set the separator as " is " between variable names and their values.
Using one of the methods from the StandardToStringStyle class, set the separator as "; " between variable-value pairs.
Using one of the methods from the StandardToStringStyle class, add a "." at the end of the string.
To output the string in the desired format, use the static method reflectionToString from the ToStringBuilder class.

Expected output in the Solution class:

This person's name is Bob; age is 33; weight is 80; height is 179; sex is male.
This person's name is Mary; age is 35; weight is 60; height is 165; sex is female.

P. S. To solve this task, it is recommended to use the Apache Commons Lang3 library version 3.9.

Requirements:

Do not modify the Solution class.
Do not modify the variables of the Person class.
Do not modify the constructor of the Person class and do not create new ones.
The toString method of the Person class should return a string in the specified format.
The main method of the Solution class should output two strings according to the specified conditions.

Just realized that the field is transient. It was therefore not included in the standard output. I had to use: return ToStringBuilder.reflectionToString(this, style, true); So one additional parameter in the refelectionToString method...
