How to loop through an array of objects in java?

Question

Java

Hello.
I apologize in advance if I'm asking a too primitive question, but Google does not return results or I cannot formulate the question correctly.
How can one iterate over an array of objects in Java?
those. the structure is as follows:

[
   {
      "name":"Alex",
     "age":"40"
    },
{
      "name":"John",
     "age":"40"
    }
]

In PHP it's clear that foreach is inside foreach. And here I can not understand, swears at type errors. My tried methods:

for (Object child : m.getChilds()) {
        for (String field : child){
            System.out.println(field.name);
        }
    }

Here, m.getChilds() contains the entire array, child, respectively, objects. Of course my writing is nonsense, but I hope I correctly conveyed my idea. Thanks

The trick is that the compiler will not see your fields in the object class. Create a class with the desired structure and just cast an object to it.
