can someone explain me the exact use of the "new" keyword

Answer 1

for example you have a class Owl and in some main method of main class you want to use an Owl instance you declaring for example

Owl owl = new Owl();

and you get an owl instance of Owl Class.
this instance can have defined values of fields and if you create next:

Owl nextOwl=new Owl();

and with some setter-methods you define nextOwl fields values you will have two innstances of one class with different values.

So - "new" is a spell to create a new instance of class

Answer 2

the new keyword means you are simply allocating memory to the program for instantiation.

Answer 3

the "new" keyword allocates block of memory without giving it a name:

int x; // allocate 4 bytes of memory for the variable named x
new int; // allocate a part of 4 bytes of memory without giving it a name;

• We can reach an object in memory using either it's name or it's address.
Hence, the seconde statement is useless since no one can reach that position in memory.

• How we can benefit of "new" ?
one of the benefits of using "new" is when we use pointers:

int *p=&x; // we can reach *p from the pointer p or directly by using it's name "x" (e.g) x=34 ≈ *p=34
int *p=new int; // we can reach *p only from the pointer name; (e.g) *p=13;
// and this protects *p from being modified using x
