Java Double max() Method

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

Syntax

Parameters

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

Return value

The max() method returns the greater value amongst a and b.

Example 1

import java.util.Scanner;

public class Double_maxMethodExample1 {
    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 greater of two values
        Double d3= Double.max(d1,d2);
        System.out.println("Enter third number");
        Double d4 =scanner.nextDouble();
        Double d5 =Double.max(d3,d4);
        System.out.println("The Max value is: "+d5);
    }
}

Test it Now

Output:

Enter first number.
67
Enter second number
89.001
Enter third number
89.0011
The Max value is: 89.0011

Example 2

import java.util.Scanner;

public class Double_maxMethodExample2 {
    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;
        for (int i = 0; i < n - 1; i++) {
            // return the max of n numbers
            d1 = Double.max(a[i], a[i+1]);
            a[i+1] = d1;


            //System.out.println(d1);
        }
        System.out.println("Maximum value : " + d1);

    }
    
}

Test it Now

Output:

Enter total number of elements
5
Enter 5 elements
90.009
98.887
67.8898
7566
77
Maximum value : 7566.0

Example 3

import java.util.Scanner;

public class Double_maxMethodExample3 {
    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 f1, temp = 0.0;
        for (int i = 0; i < n ; i++) {
            for (int j = i+1; j < n; j++) {
                f1 = Double.max(a[i], a[j]);
                if (a[i].equals(f1)){
                    //temp = f1;
                    a[i] = a[j];
                    a[j] = f1;
                }
            }
        }
        System.out.print("Descending order = ");
        for (int i = n-1; i >=0; i--) {
            System.out.print(a[i]+",");
        }
    }
}

Test it Now

Output:

Enter number of elements you want.
5
Enter elements
90.009
90.00008
90
89
89.999
Descending order = 90.009,90.00008,90.0,89.999,89.0,
