# 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```

Below programs illustrate the Java.lang.Integer.sum() method:
Program 1: For a positive number.

 `// Java program to illustrate the ` `// Java.lang.Integer.sum() method ` `import` `java.lang.*; ` ` `  `public` `class` `Geeks { ` ` `  `    ``public` `static` `void` `main(String[] args) ` `    ``{ ` `        ``int` `a = ``62``; ` `        ``int` `b = ``18``; ` `        ``// It will return the sum of two arguments. ` `        ``System.out.println(``"The sum is ="` `+ Integer.sum(a, b)); ` `    ``} ` `} `

Output:

```The sum is =80
```

Program 2: Below program illustrates the exception.

 `// Java program to illustrate the ` `// Java.lang.Integer.sum() method ` `import` `java.lang.*; ` ` `  `public` `class` `Geeks { ` ` `  `    ``public` `static` `void` `main(String[] args) ` `    ``{ ` `        ``// When very large integer is taken ` `        ``int` `a = ``92374612162``;  ` `        ``int` `b = ``181``; ` `        ``// It will return the sum of two arguments. ` `        ``System.out.println(``"The sum is ="` `+ Integer.sum(a, b)); ` `    ``} ` `} `

Output:

```prog.java:8: error: integer number too large: 92374612162
int a = 92374612162;
^
1 error
