Java Math.negateExact() method

The java.lang.Math.negateExact() returns the negation of the argument. It will throw an exception if the result overflows either int or long.

Syntax

Parameter

Return

If the argument is Integer.MIN_VALUE or Long.MIN_VALUE, it will throw an ArithmeticException.

Example 1

  public class NegateExactExample1  {      public static void main(String[] args)       {          int a = 379;          // Input a, Output -a          System.out.println(Math.negateExact(a));      }  }  

Test it Now

Output:

-379

Example 2

  public class NegateExactExample2  {      public static void main(String[] args)       {          long a = -830;          // Input -a, Output a          System.out.println(Math.negateExact(a));      }  }  

Test it Now

Output:

Example 3

  public class NegateExactExample3  {      public static void main(String[] args)       {          int a = Integer.MIN_VALUE;          // Input int overflow, Output ArithmeticException          System.out.println(Math.negateExact(a));      }  }  

Test it Now

Output:

Exception in thread "main" java.lang.ArithmeticException: integer overflow  at java.lang.Math.negateExact(Math.java:977)  at negateExactExample3.main(negateExactExample3.java:7)

Example 4

  public class NegateExactExample4  {      public static void main(String[] args)       {          long a = Long.MIN_VALUE;          // Input long overflow, Output ArithmeticException          System.out.println(Math.negateExact(a));      }  }  

Test it Now

Output:

Exception in thread "main" java.lang.ArithmeticException: long overflow  at java.lang.Math.negateExact(Math.java:994)  at negateExactExample4.main(negateExactExample4.java:7)
