Float compare() Method in Java with Examples

Last Updated : 11 Jul, 2025

The compare() method of Float Class is a built-in method in Java that compares the two specified float values. The sign of the integer value returned is the same as that of the integer that would be returned by the function call.

Syntax:

public static int compare(float f1, float f2)

Parameters: The function accepts two parameters:

f1: The first float value to be compared.
f2: The second float value to be compared.

Return Value: The function returns value as below:

0: if f1 is numerically equal to f2.
Negative value: if f1 is numerically less than f2.
Positive value: if f1 is numerically greater than f2.

Below programs illustrates the use of Float.compare() function:

Program 1: When two integers are same

Java

// Java Program to illustrate
// the Float.compare() method

import java.lang.Float;

public class GFG {
    public static void main(String[] args)
    {

        // Get the two float values
        // to be compared
        Float f1 = 1023f;
        Float f2 = 1023f;

        // function call to compare two float values
        if (Float.compare(f1, f2) == 0) {

            System.out.println("f1=f2");
        }
        else if (Float.compare(f1, f2) < 0) {
            System.out.println("f1<f2");
        }
        else {

            System.out.println("f1>f2");
        }
    }
}

Output

f1=f2

Program 2 : When f1<f2

Java

// Java Program to illustrate
// the Float.compare() method

import java.lang.Float;

public class GFG {
    public static void main(String[] args)
    {

        // Get the two float values
        // to be compared
        Float f1 = 10f;
        Float f2 = 1023f;

        // function call to compare two float values
        if (Float.compare(f1, f2) == 0) {

            System.out.println("f1=f2");
        }
        else if (Float.compare(f1, f2) < 0) {

            System.out.println("f1<f2");
        }
        else {
            System.out.println("f1>f2");
        }
    }
}

Output

f1<f2

Program 3 : When f1>f2

Java

// Java Program to illustrate
// the Float.compare() method
import java.lang.Float;

public class GFG {
    public static void main(String[] args)
    {
        // Get the two float values
        // to be compared
        Float f1 = 1023f;
        Float f2 = 10f;

        // function call to compare two float values
        if (Float.compare(f1, f2) == 0) {
            System.out.println("f1=f2");
        }
        else if (Float.compare(f1, f2) < 0) {
            System.out.println("f1<f2");
        }
        else {
            System.out.println("f1>f2");
        }
    }
}

Output

f1>f2
