Java Double min() Method

The min() method of Java Double class returns the double having minor value amongst two double values. The result returned is same as by invoking Math.min () method.

Syntax

Parameters

Here, a & b are the two operands to be compared.

Return value

The min() method returns the lesser value amongst a and b.

Example 1

import java.util.Scanner;

public class Double_minMethodExample1 {
        public static void main(String[] args) {
            Scanner scanner = new Scanner(System.in);
            System.out.println("Enter first number.");
            Double d1 = scanner.nextDouble();
            System.out.println("Enter second number");
            Double d2 = scanner.nextDouble();
            //return the smaller of two values
            Double d3= Double.min(d1,d2);
            System.out.println("Enter third number");
            Double d4 = scanner.nextDouble();
            Double d5= Double.min(d3,d4);
            System.out.println("The smaller number is: "+d5);
        }
    }

Output:

Enter first number.
67.90
Enter second number
67.89
Enter third number
67.99999
The smaller number is: 67.89

Example 2

import java.util.Scanner;

    public class Double_minMethodExample2 {
        public static void main(String[] args) {
            Scanner scanner = new Scanner(System.in);
            System.out.println("Enter total number of elements");
            int n = scanner.nextInt();
            // creating array
            Double a[] = new Double[n];
            System.out.println("Enter " + n + " elements");
            for (int i = 0; i < n; i++) {
                a[i] = scanner.nextDouble();
            }
            Double d1 = 0.0;
            Double d2 =0.0;
            for (int i = 0; i < n - 1; i++) {
                // return the maximum value of n numbers
                d1 = Double.max(a[i], a[i + 1]);
                a[i+1] = d1;
            }
            System.out.println("Maximum value : " + d1);
            for (int i = 0; i < n - 1; i++) {
                // return the minimum value of n numbers
                d2 = Double.min(a[i], a[i+1]);
                a[i+1] = d2;
            }
            System.out.println("Minimum value : "+d2);
        }
    }

Output:

Enter total number of elements
4
Enter 4 elements
100.098
100.9876
19635
100
Maximum value : 19635.0
Minimum value : 100.098

Example 3

import java.util.Scanner;

public class Double_minMethodExample3 {
       public static void main(String[] args) {
            Scanner scanner = new Scanner(System.in);
            System.out.println("Enter number of elements you want.");
            int n = scanner.nextInt();

            Double a[] = new Double[n];
            System.out.println("Enter elements");
            for (int i = 0; i < n; i++) {
                a[i] = scanner.nextDouble();
            }
            Double d1, temp = 0.0;
            for (int i = 0; i < n ; i++) {
                for (int j = i+1; j < n; j++) {
                    d1 = Double.min(a[i], a[j]);
                    if (a[i].equals(d1)){
                        temp = d1;
                        a[i] = a[j];
                        a[j] = temp;
                    }
                }
            }
            System.out.print("Descending order = ");
            for (int i = 0; i < n; i++) {
                System.out.print(a[i]+">");
            }
        }
    }

Output:

Enter number of elements you want.
4
Enter elements
10.000
10,001
11
12
Descending order = 10001.0>12.0>11.0>10.0>

Example 4

public class Double_minMethodExample4 {
       public static void main(String[] args) {
            Double d1=Double.MIN_VALUE;
            System.out.println("Min_Value = "+d1);
            Double d2=Double.MIN_NORMAL;
            System.out.println("Min_Value = "+d2);
            Double d3=Double.min(d1,d2);
            System.out.println("1. Smaller value = "+d3);
            System.out.println();

            Double d7=Double.POSITIVE_INFINITY;
            System.out.println("POSITIVE_INFINITY = "+d7);
            Double d8=Double.NEGATIVE_INFINITY;
            System.out.println("NEGATIVE_INFINITY = "+d8);
            Double d9 =Double.min(d7,d8);
            System.out.println("2. Smaller value = "+d9);
        }
    }
	

Output:

Min_Value = 4.9E-324
Min_Value = 2.2250738585072014E-308
1. Smaller value = 4.9E-324

POSITIVE_INFINITY = Infinity
NEGATIVE_INFINITY = -Infinity
2. Smaller value = -Infinity
