Thread: How java programs store in Heap and Stack.

Hi.
I started java programming few weeks ago. Im trying to understand how java objects, variable and main program stored inside heap and stack.
I marked with question marks for places where i want to know. Please help me to understand.

class Student{
    int age;               // ?
    String name;     // ? 
 
    public Student() //  ?
    {
        this.age = 0;
        name = "Anonymous";
    }
    public Student(int Age, String Name) // Parameter int Age and String Name ? 
    {
        this.age = Age;
        setName(Name);
    }
    public void setName(String Name) // method and parameter ?
    {
        this.name = Name;
    }
}
 
public class Main{  
	public static void main(String[] args) { // public method ?
            Student s;                   // ?
            s = new Student(23,"Jonh");
            int noStudents = 1;          //local variable
	}
}

Thank you for your reply. Currently im studding java in a Institute. I got some programs to resolve. But i have to explain in a way how java programs work with memory when running these programs.
