Demo of Java long

Here is the demo of Java long −

public class JavaLongDemo {
   public static void main(String[]args) {
      long kilometer = 9223372036854775807L;
      System.out.println("The largest positive value for long range:"+kilometer);
   }
}

The following is the output −

Demo of BigInt

Let us see an example of BigInt type in MySQL. The following is the query to create a table with field set as BigInt −

mysql> create table BigIntDemo
   −> (
   −> Kilometer BigInt
   −> );
Query OK, 0 rows affected (0.74 sec)

Inserting some records in the table. The query is as follows −

mysql> insert into BigIntDemo values(9223372036854775807);
Query OK, 1 row affected (0.19 sec)

Now you can check whether the above record is inserted or not. The select query is as follows −

mysql> select *from BigIntDemo;

The following is the output −

+---------------------+
| Kilometer           |
+---------------------+
| 9223372036854775807 |
+---------------------+
1 row in set (0.00 sec)
