Math.max() Method in Java

Math.max() Method in Java use in java to find maximum number to given two number. Math.max Java method is defined in java.lang.Math class . Java Math.max method Returns the greater of two given values.There are several overloaded forms of the Math.max java method as

Syntax of Math.max()

public static int max(int a, int b)
public static long max(long a, long b)
public static float max(float a, float b)
public static double max(double a, double b)

There is max a static method and we can access using class name Math it .

max() Parameters :

max method takes two arguments arg1 , arg2 . These argument can be int ,long , float and double.

max() Return Value

Math.max method return greater value of given two arguments .

Math.max() Examples in Java

package com.demo.program;

public class MathMax {
	public static void main(String[] args) {		
		System.out.println(Math.max(10, 20));
		System.out.println(Math.max(10.5, 9));
		System.out.println(Math.max(100, 50));		
	}

}

Output :

20
10.5
100

Special Cases of Java Math.max()

1). If the arguments have the same values, then the result is also the same value.

public class MathMax {
	public static void main(String[] args) {		
		System.out.println(Math.max(10, 10));
	}

}

Output :

10

2). If we provide positive and negative value as argument, this method will return positive argument.

public class MathMax {
	public static void main(String[] args) {		
		System.out.println(Math.max(2, -5));
	}

}

Output :

2

3). If we provide both negative values as argument, number with the lower magnitude is returned as result.

public class MathMax {
	public static void main(String[] args) {		
		System.out.println(Math.max(-2, -5));
	}

}

-2

4). If the arguments are not a number(NaN), this method will return NaN.

public class MathMax {
	public static void main(String[] args) {		
		System.out.println(Math.max(Double.NaN, -5));
		System.out.println(Math.max(80.5f , Double.NaN));
		System.out.println(Math.max(70 , Double.NaN));
	}

}

Output :

NaN
NaN
NaN

In this article we have learned about Java math.max method . This is very useful method if you want to compare two numbers . math.max java is static method and can access with class name Math. You can learn more java coding program for interview .
