@Acer since Tomato() is only a special case of Tomato(int size), you may try
Tomato(){
this(_default_size);
}
not sure, I’m no java expert XD
I would simply set the member foodName to "Tomato", and every time you need the name, you do "this.foodName" or "getFoodName()"..
it will throw error if writing foodName directly.
I dont know the exact reason. maybe it is because foodname is private variable of Food instead of Tomato

@Acer whats the language? looks like Java maybe?
@Acer Whatever the language, shouldn't the function be able to have an 'optional input' so you can set a default if no input is found?
@Acer Looks like Java doesn't have optional parameters. Another reason for me to try to forget this language even exists. ;)
Java does have some tricks to mimic this. Check this page, it gave me some idea about those tricks:
https://stackify.com/optional-parameters-java/
The tricks on the page is not applied to constructor or I already applied accessors
@Acer Tomato (){this(121)}不知道你指的是不是这个意思
java沒有這個語法好像 看不懂這個表達式意思
@Acer java是不能设置默认参数， 起码得两个构造函数。this（121）这一行调用自己的带参数构造函数。this是自己这个类的意思
