Java Float - parseFloat() Method

The java.lang.Float.parseFloat() method returns a new float initialized to the value represented by the specified String, as performed by the valueOf method of class Float.

Syntax

public static float parseFloat(String s)
                        throws NumberFormatException

Parameters

Return Value

Returns the float value represented by the string argument.

Exception

• Throws NullPointerException, if the string is null.
• Throws NumberFormatException, if the string does not contain a parsable float.

Example:

In the example below, the java.lang.Float.parseFloat() method is used to parse the string argument as a float value.

import java.lang.*;

public class MyClass {
  public static void main(String[] args) {
    
    //creating a string holding float value
    String x = "25.2";

    //creating float value
    float y = Float.parseFloat(x);

    //printing the string
    System.out.println("The string is: " + x); 

    //printing the float value
    System.out.println("The float value is: " + y);   
  }
}

The output of the above code will be:

The string is: 25.2
The float value is: 25.2
