# Java Math max() method with Examples

The Java.lang.math.max() function is an inbuilt function in Java which returns maximum of two numbers. The arguments are taken in int, double, float and long.If a negative and a positive number is passed as argument then the positive result is generated. And if both parameters passed are negative then the number with the lower magnitude is generated as result.

Syntax:

```dataType max(dataType num1, dataType num2)
The datatypes can be int, float, double or long.

Parameters : The function accepts two parameters num1 and num2
among which the maximum is returned
```

Return value:The function returns maximum of two numbers. The datatype will be the same as that of the arguments.

Given below are the examples of the function max()

 `// Java program to demonstrate the use of max() function``// when two double data-type numbers are``// passed as arguments``public` `class` `Gfg {`` ` `    ``public` `static` `void` `main(String args[])``    ``{``        ``double` `a = ``12.123``;``        ``double` `b = ``12.456``;`` ` `        ``// prints the maximum of two numbers``        ``System.out.println(Math.max(a, b));``    ``}``}`

Output:

```12.456
```

 `// Java program to demonstrate the use of max() function``// when one positive and one negative``// integers are passed as argument``public` `class` `Gfg {`` ` `    ``public` `static` `void` `main(String args[])``    ``{``        ``int` `a = ``23``;``        ``int` `b = -``23``;`` ` `        ``// prints the maximum of two numbers``        ``System.out.println(Math.max(a, b));``    ``}``}`

Output:

```23
```

 `// Java program to demonstrate the use of max() function``// when two negative integers are passed as argument.``public` `class` `Gfg {`` ` `    ``public` `static` `void` `main(String args[])``    ``{``        ``int` `a = -``25``;``        ``int` `b = -``23``;`` ` `        ``// prints the maximum of two numbers``        ``System.out.println(Math.max(a, b));``    ``}``}`

Output:

```-23
```
