JVM memory structure when creating objects

Code

1. Student class :

public class Student {
    
    int no;
    String name;
    int age;
    boolean sex;
    String address;
}

2. StudentTest class :

public class StudentTest {
    
    public static void main(String[] args) {
    
        Student s1 = new Student();
        Student s2 = new Student();
    }
}

JVM Corresponding memory structure diagram in

note:

1. s1、s2 It's a local variable ( Variables created in methods ), Local variables are stored in stack memory
2. The difference between objects and references ?

• The object is through new Coming out , Store... In heap memory
• The quotation is : But all variables , And the memory address is saved in this variable , Points to the object in the heap memory ( In this case main Variable in method s1、s2 Is to save the object Student Address in heap memory )
