}long vs int java
An int is a 32-bit integer; a long is a 64-bit integer. Which one to use depends on how large the numbers are that you expect to work with.
int and long are primitive types, while Integer and Long are objects.
Primitive types are more efficient, but sometimes you need to use objects;
for example, Java's collection classes can only work with objects,
so if you need a list of integers you have to make it a List<Integer>, for example (you can't use int in a List directly).what is primitive data type in java
Primitive types are the most basic data types available within the Java language. There are 8: boolean , byte , char , short , int , long , float and double . These types serve as the building blocks of data manipulation in Java. Such types serve only one purpose — containing pure, simple values of a kind.Copyright © 2021 Codeinu
