In this example, we shall show you how to find the maximum numbers in Java, using the Math Class and the method Math.max.
1. About Math Class
The java.lang.Math class contains methods for performing basic numeric operations such as the elementary exponential, logarithm, square root, and trigonometric functions.
By using the associated functions directly, you can skip creating the logic of all the functions. Every mathematical operation/function is in one way or the other part of the Math Class. Few of the examples include sin(), tan(), cos(), abs(),log(), log10() and many others.
Among all the mentioned above methods, one such method is max(). Let us read more to understand what it does.
2. Math.max method in Java
Math.max() is used to find out the largest of two numbers. It takes two parameters and returns the larger of the two. The data type of the returning variable is the same as the input parameters.
Use the max(double a, double b), max(float a, float b), max(int a, int b), max(long a, long b) API methods of Math according to the types of arguments to get the greater of the two values, as described in the code snippet below.
3. Math.max examples in Java
In the first example below, we will be demonstrating the usage of Math.max() with different data types.
Example 1
01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 21 | package com.javacodegeeks.snippets.core;public class FindMaximumOfNumbersWithMathMax { public static void main(String[] args) { // maximum of two integers System.out.println(Math.max(10,50)); // maximum of two float values System.out.println(Math.max(21.64f,56.8f)); // maximum of two double values System.out.println(Math.max(15.94,23.15)); // maximum of two long values System.out.println(Math.max(1234L,9876L)); }} |
Output
50 56.8 23.15 9876
In the second example below, we will be using Math.max()with positive and negative values.
Example 2
01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 | package com.javacodegeeks.snippets.core;public class FindMaximumOfNumbersWithMathMax { public static void main(String[] args) { maximum of two positive integers System.out.println(Math.max(10,50)); // maximum of two negative values System.out.println(Math.max(-10,-50)); // maximum of one positive and one negative value System.out.println(Math.max(-10,50)); }} |
Output
50 -10 50
