# Java – Find Absolute Value of Long – abs() Method with Examples

`java.lang.Math.abs()` method is used to find the absolute value of a long in Java for the given input (`x` – parameter) in Java. If the argument is not negative, the argument is returned. If the argument is negative, the negation of the argument is returned.

## Package

`abs()` method exists in `Math` class of `java.lang` package.
Since: JDK1.0

## Method Declaration of `abs()` Method

The declaration of `abs()` method is:

## Syntax of `abs()` Method

The syntax of `abs()` method in Java is:

Example

Output:
`96389`
Example
By importing `java.lang` package the syntax of `abs()` method can be used as:

Output:
`98674`

## Special Cases of `abs()` Method in Java

Note that if the argument is equal to the value of Long.MIN_VALUE, the most negative representable long value, the result is that same value, which is negative.
Example

Output:
`0 0 -9223372036854775808 0`

## Parameters of `abs()` Method in Java

`x` – Where `x` is any valid long input value. This parameter is required.

## Error Handling

If the `x` parameter is not a number `abs()` method returns an `error`.
If there is no argument (`x` – input value) passes to the method, the compiler will produce an `error`.
Example

Output:
`Error`

## Return Value of `abs()` Method in Java

`abs()` method returns the absolute value of a long value for the given input (`x` – parameter).

## Java `abs()` Method Example 1

Output:
`absolute value of a Negative Value: 867324 absolute value of a Positive Value: 35843 absolute value of Zero: 0`

## Java `abs()` Method Example 2

Output:
`9223372036854775807 -9223372036854775808 0 5555 0 7 -9223372036854775808`
