◕ Use of Underscores to write an integer in Java.
We insert underlines to make the literal easier to read.
The explanation and the example are given bellow.
In Java we can write integer within 4 types. They are:
To write a long type integer we have to write:
long stars = 9876543210L; // a Java statement
The L in the suffix of the number indicates that it a long type integer.
When we write a long type integer like this 9876543210L it sometimes looks difficult to read. Hence to make it easy to read use the Underscores like 9_876_543_210L.
But there are some rules to use Underscores.
- 1) We can use multiple Underscores in a integer type.
long stars = 9__876__543__210L;
- 2) The both side of the Underscore / Underscores must be bound by digits or Underscore.
