Java Math.addExact() method

The java.lang.Math.addExact() returns the sum of its arguments. It will throw an exception if the result overflows either int or long.

Syntax

  public static int addExact(int a, int b)   public static long addExact(long a, long b)  

Parameter

Return

If one of the arguments is Integer.MAX_VALUE or Long.MAX_VALUE, it will throw an ArithmeticException.

Example 1

  public class AddExactExample1  {      public static void main(String[] args)       {          int a = 469;          int b = 737;          // Input two positive value, Output addition of a and b          System.out.println(Math.addExact(a, b));      }  }  

Test it Now

Output:

Example 2

  public class AddExactExample2  {      public static void main(String[] args)       {          long a = 835;          long b = -1573;          // Input two values, Output addition of a and b           System.out.println(Math.addExact(a, b));      }  }  

Test it Now

Output:

-738

Example 3

  public class AddExactExample3  {      public static void main(String[] args)       {          int a = Integer.MAX_VALUE;          int b = 785;          // Input integer overflow, Output AirthmeticException           System.out.println(Math.addExact(a, b));      }  }  

Test it Now

Output:

Exception in thread "main" java.lang.ArithmeticException: integer overflow  at java.lang.Math.addExact(Math.java:790)  at AddExactExample3.main(AddExactExample3.java:8)

Example 4

  public class AddExactExample4  {      public static void main(String[] args)       {          long a = 25;          long b = Long.MAX_VALUE;          // Input long overflow, Output AirthmeticException           System.out.println(Math.addExact(a, b));      }  }  

Test it Now

Output:

Exception in thread "main" java.lang.ArithmeticException: long overflow  at java.lang.Math.addExact(Math.java:809)  at AddExactExample4.main(AddExactExample4.java:8)
