Question

So, apparently when I asked this before, I instead of actually getting an answer, I just got my own code spit back at me. What I'm actually trying to do is convert the python code (image) into Java, and for some reason, my code isn't compiling, and I have no idea why. I'll post my work so far, but I want to know why it isn't working in the first place.

class Person{

public String Name;

this.Name = Name;

this.Age = Age;

String result = "";

result += Name + " is ";

if (isStudent = "True") {

result += "a student ";
