Java - Float Class parseFloat() Method

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

Float class parseFloat() method

parseFloat() method is available in java.lang package.
parseFloat() method is used to return the float value corresponding to the given String denotation or in other words we can say this method is used to convert string value to a float value.
parseFloat() method is a static method, it is accessible with the class name too and if we try to access the method with the class object then also we will not get an error.
parseFloat() method may throw a NumberFormatException at the time of conversion from string to float.
NumberFormatException: In this exception, when the string argument does not have a parsable float.

Syntax

public static float parseFloat (String str);

Parameters

String str – represents the string value to be parsed.

Return Value

The return type of this method is float, it returns the corresponding float value that represent the String value.

Example

// Java program to demonstrate the example 
// of parseFloat(String str) method of 
// Float class

public class ParseFloatOfFloatClass {
    public static void main(String[] args) {
        // Variables initialization
        String str1 = "100";
        String str2 = "6.7";

        // Object initialization
        Float f1 = new Float(str2);

        // It convert string into float by calling parseFloat() method
        // and store the result in another variable of float type
        float result = f1.parseFloat(str1);

        // Display result
        System.out.println("f1.parseFloat(str1): " + result);
    }
}

Output

f1.parseFloat(str1): 100.0
