    Question 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
    	}
    }

    Where the java program puts the parts of the program when the program is executing depends on the java program's implementation. Usually class objects go in the heap and method variables on the stack.
    Why are you interested in where data is put in memory?
    If you don't understand my answer, don't ignore it, ask a question.

    Why is a beginning programming course concerned about how the java program uses memory?
    There is so many other things to learn.
