Java Math min method example shows how to find a minimum of two numbers using the min method of the Java Math class.
How to find a minimum of two numbers using Math class?
We can use the min static method of the Java Math class to find a minimum of two numbers.
|
1 |
public static int min(int x, int y) |
This method returns a minimum of two integer numbers.
The min method has been overloaded for double, float, and long data types so that the same method can be used for all of them.

package com.javacodeexamples.mathexamples; public class FindMinNumberExample { public static void main(String[] args){ int i1 = -21; int i2 = -20; //find minimum of two integer numbers System.out.println( "Minimum Integer number: " + Math.max(i1, i2) ); long l1 = 2314l; long l2 = 1235l; //find minimum of two long numbers System.out.println( "Minimum long number: " + Math.max(l1, l2) ); float f1 = 7654.534f; float f2 = 7654.533f; //find minimum of two float numbers System.out.println( "Minimum float number: " + Math.max(f1, f2) ); double d1 = 58334.34d; double d2 = 58334.35d; //find minimum of two double numbers System.out.println( "Minimum double number: " + Math.max(d1, d2) ); } } |

Minimum Integer number: -20 Minimum long number: 2314 Minimum float number: 7654.534 Minimum double number: 58334.35 |
How to find a minimum of 3 or more numbers?
Themin() method of the Math class accepts only two arguments. So, a minimum of 3 numbers cannot be found directly using the min method. However, we can find a min of 3 numbers like the below given example.
|
1 2 3 4 5 |
int a = 234; int b = 230; int c = 342; System.out.println( "Min of 3 numbers: " + Math.min( Math.min(a, b), c ) ); |
Output
|
1 |
Min of 3 numbers: 230 |
