Java Float equals() method

The equals() method of Float class returns a Boolean value corresponding to this Float Object by simply comparing the Float object with the given float object method argument.

Syntax:

Parameters:

The parameter obj is passed which is an object compared with other object.

Return Value:

This method returns the Boolean value of the argument.

Returns true, if the objects are same.
Return false, if the objects are not same.

Example 1

import java.lang.*;
import java.util.Scanner;

public class  FloatequalsMethodExample1 {

    private static Scanner scanner = new Scanner(System.in);

    public static void main(String[] args) {

        Float f1 = new Float(20.09);

        System.out.println("Enter password");
        float f2 = scanner.nextFloat();

        //Comparing the float object 

        if (f1.equals(f2)) {
            System.out.println("Password matched");
        } else {
            System.out.println("Incorrect password!");
        }

    }

}

Test it Now

Output:

Enter password
    20.09
    Password matched

Example 2

import java.lang.*;
import java.util.Scanner;

public class  FloatequalsMethodExample2 {

    private static Scanner scanner = new Scanner(System.in);


    public static void main(String[] args) {


        Float f1 = new Float(9.0);
        Float f2 = new Float(8.0);
        Float f3 = new Float(7.0) ;
        Float f4 = new Float(6.0);
        Float f5 = new Float(5.0);
        Float f6 = new Float(4.0);


        System.out.println("Enter marks in Maths");
        Float marks1 = scanner.nextFloat();

        System.out.println("Enter marks in English");
        Float marks2 = scanner.nextFloat();

        System.out.println("Enter marks in Hindi");
        Float marks3 = scanner.nextFloat();


        Float avg = (marks1+marks2+marks3)/3;
      Float   f7 = new Float(avg.byteValue()/10);//Using byteValue method to convert float into byte.

     // comparing whether the values are equal or not
        if(f1.equals(f7)){
            System.out.println("Your CGPA is "+f1+"\nCongratulation!\nYou passed with A+ grade");
        }

       else if(f2.equals(f7)){
            System.out.println("Your CGPA is "+f2+"\nCongratulation!\nYou passed with A grade");
        }

       else if(f3.equals(f7)){
            System.out.println("Your CGPA is "+f3+"\nWell Done !\nYou passed with B+ grade");

        }

       else if(f4.equals(f7)){
            System.out.println("Your CGPA is "+f4+"\nKeep it up!\nYou passed with B grade");
        }

       else if(f5.equals(f7)){
            System.out.println("Your CGPA is "+f5+"\nWell tired!\nYou passed with C+ grade");
        }

      else if(f6.equals(f7)){
            System.out.println("Your CGPA is "+f6+"\nNot up to mark!\nYou passed with C grade");
        }

       else {
          System.out.println("Your CGPA is 0.0.\nWork hard next time.\nYou failed.");
           }

    }

}

Enter marks in Maths
98
Enter marks in English
90
Enter marks in Hindi
90
Your CGPA is 9.0
Congratulation!
You passed with A+ grade

Example 3

import java.util.Scanner;

public class FloatequalsMethodExample3 {

    public static void main(String[] args) {
        System.err.println("If there are 4 apples.You take away 2 apples.How many do you have in hands?");
        System.err.println("1. 1 apple\n2. 2 apples\n3. 3apple ");

        Float f1=new Float(1);
        Float f2= new Float(2);
        Float f3=new Float(3);

        Scanner scanner=new Scanner(System.in);
        System.out.println("Enter your option.");
        Float answer=scanner.nextFloat();

    if(f1.equals(answer)){
        System.out.println("Wrong answer!");
    }
    else if(f2.equals(answer)){
        System.out.println("Right answer!");
    }
    else{
        System.out.println("Wrong answer!");
    }
    }
}
