Java Float min() Method:

The min() method of Java Float class returns the float having minimum value between two float values. The result returned is same as by invoking Math.min () method.

Syntax:

Parameters:

Here a & b are the two float operands that are compared.

Return Value:

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

Example 1

import java.util.Scanner;

public class FloatMinExample1 {

        public static void main(String[] args) {
            Scanner scanner = new Scanner(System.in);
            System.out.println("Enter first number.");
            Float f1 = scanner.nextFloat();
            System.out.println("Enter second number");
            Float f2 = scanner.nextFloat();
            //return the smaller of two values
            Float f3= Float.min(f1,f2);
            System.out.println("The smaller number is: "+f3);
        }
    }

Output:

Enter first number.
-1.112
Enter second number
-66.112
The smaller number is: -66.112

            int n = scanner.nextInt();
            // creating array
            Float a[] = new Float[n];
            System.out.println("Enter " + n + " elements");
            for (int i = 0; i < n; i++) {
                a[i] = scanner.nextFloat();
            }
            Float f3 = 0f;
            Float f4 =0f;
            for (int i = 0; i < n - 1; i++) {
                // return the maximum value of n numbers
                f3 = Float.max(a[i], a[i + 1]);
                a[i+1] = f3;
            }
            System.out.println("Maximum value : " + f3);
           for (int i = 0; i < n - 1; i++) {
               // return the minimum value of n numbers
               f4 = Float.min(a[i], a[i+1]);
               a[i+1] = f4;
           }
           System.out.println("Minimum value : "+f4);
       }
    }
