Java - Float Class compare() Method

Float class compare() method: Here, we are going to learn about the compare() method of Float class with its syntax and example. By Preeti Jain Last updated : March 21, 2024

Float class compare() method

compare() method is available in java.lang package.
compare() method is used to check equality or inequality of the given two float values or in other words, we can say this method is used to compare two float values.
compare() method is a static method, it is accessible with the class name too and if we try to access the method with a class object then also, we will not get an error.
compare() method does not throw an exception at the time of comparing float values.

Syntax

public static int compare(float value1, float value2);

Parameters

float value1, float value2 – represent the float values to be compared.

Return Value

The return type of this method is int, it returns an integer value, based on the following conditions,

It returns 0 if value1 is mathematically equal to value2.
It returns the value < 0 if value1 is mathematically less than value2.
It returns the value > 0 if value1 is mathematically greater than value2.

Example

// Java program to demonstrate the example 
// of compare(float value1,float value2) 
// method of Float class

public class CompareOfFloatClass {
    public static void main(String[] args) {
        // Variables initialization
        float value1 = 18.20f;
        float value2 = 20.20f;

        // It compare two float values and placed the result 
        // in another variable (compare) of integer type
        int compare = Float.compare(value1, value2);

        // Display result
        System.out.println("Float.compare(value1,value2): " + compare);
        System.out.println();

        if (compare == 0)
            System.out.println("value1 is equal to value2");
        else if (compare < 0)
            System.out.println("value1 is less than value2");
        else
            System.out.println("value1 is greater than value2");
    }
}

Output

Float.compare(value1,value2): -1

value1 is less than value2
