Convert Integer to Long Java

In Java, you can convert an Integer object to a long type using the longValue() method. Here is an example code:

Integer integerObj = new Integer(10);
long longValue = integerObj.longValue();

System.out.println(longValue);

The output is as follows:

10

Caution: If the value of an Integer object exceeds the range of a long type, the conversion result may overflow.
