//Main method which signify the beginning of program execution

public static void main(String[] args) {

//myInt variable of type Integer is declared

Integer myInt;

// An object of type Integer is declared with initial value of 1

Integer newInt = new Integer(1);

// The value of the new declared and assigned object is displayed to the user

System.out.println(newInt);

// The new declared object is assigned to the reference variable myInt

myInt = newInt;

// The value of myInt is displayed to the user

System.out.println(myInt);
