toIntExact()

Example

Convert long values to int:

System.out.println(Math.toIntExact(1500000L));
System.out.println(Math.toIntExact(-32L));
System.out.println(Math.toIntExact(-86345L));
System.out.println(Math.toIntExact(25L));

Definition and Usage

The tointExact() method converts a long value to an int, triggering an exception if the conversion leads to overflow. This prevents inaccuracies that may arise from overflow situations.

Parameter Values

Parameter	Description
x	Required. An integer to negate.

Technical Details
