Integer sum() Method in Java

The java.lang.Integer.sum() is a built-in method in java which returns the sum of its arguments. The method adds two integers together as per the + operator.

Syntax : 

public static int sum(int a, int b)

Parameter: The method accepts two parameters which are to be added with each other:
a : the first integer value.
b : the second integer value.

Return Value: The method returns the sum of its arguments.
Exception: The method throws an ArithmeticException when the result overflows an int.

Examples

Input: a = 170, b = 455
Output: 625

Input: a = 45, b = 45
Output: 90
