Java Integer min() Method

The min() is a method of Integer class under java.lang package. This method numerically returns the minimum value amongst the two method argument specified by a user. This method can be overloaded and it takes the arguments in int, double, float and long.

Note: If a positive and a negative number is passed as an argument, it generated the negative result. And if both the parameters passed as a negative number, it generates a result with the greater magnitude.

Syntax:

Following is the declaration of min() method:

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

Parameter:

DataType	Parameter	Description	Required/Optional
int	a	Numeric value entered by a user.	Required
int	b	Numeric value entered by a user.	Required

Returns:

The min() method returns the smaller value amongst the two method argument specified by a user.

Exceptions:

Compatibility Version:

Java 1.5 and above

Example 1

public class IntegerMinExample1 {
	public static void main(String[] args) {
		// Get two integer numbers
	      int a = 5485;
	      int b = 3242;   
	      // print the smaller number between x and y
	      System.out.println("Math.min(" + a + "," + b + ")=" + Math.min(a, b));
	}
}

Output:

Math.min(5485,3242)=3242

Example 2

import java.util.Scanner;
public class IntegerMinExample2 {
	public static void main(String[] args) {
		//Get two integer numbers from console
		System.out.println("Enter the Two Numeric value: ");
		Scanner readInput= new Scanner(System.in);
		int a = readInput.nextInt();
		int b = readInput.nextInt();
		readInput.close();			   
	      //Print the smaller number between a and b
	      System.out.println("Smaller value of Math.min(" + a + "," + b + ") = " + Math.min(a, b));
	}
}

Output:

Enter the Two Numeric value: 
45
76
Smaller value of Math.min(45,76) = 45

Example 3

public class IntegerMinExample3 {
	public static void main(String[] args) {
	  //Get two integer numbers
	  int a = -70;
        int b = -25;
        // prints result with greater magnitude
        System.out.println("Result: "+Math.min(a, b));
	}
}

Output:

Result: -70

Example 4

public class IntegerMinExample4 {
	public static void main(String[] args) {
	  //Get two integer numbers
	  int a = -20;
        int b = 25;
        // prints result with negative value
        System.out.println("Result: "+Math.min(a, b));
	}

Output:
