Java Float floatValue() method

The floatValue() method of Java Float class returns the float value of this object.

Syntax:

Parameters:

Return Value:

This method returns the float value of the argument.

Example 1

  public class Float_floatValueMethod_Example1 {      public static void main(String[] args) {                           Float f1=5f;            System.out.println(f1);          System.out.println( “Result after being converted to float value = “+f1.floatValue());                //method would convert to float value            Float f2 = new Float(5.7f);            System.out.println(“Result after being converted to float value = “+f2.floatValue());      }    }  

Test it Now

Output:

Result after being converted to float value = 5.0  Result after being converted to float value = 5.7

Example 2

  public class Float_floatValueMethod_Example2 {      public static void main(String[] args) {                    float f1=5f;            Float  f2=f1.floatValue();            System.out.println( “float value = “+f2);              //this is the correct way of declaring Float class method            Float f3 = new Float(5.7f);            System.out.println(“Result after being converted to float value = “+f3.floatValue());      }    }  

Test it Now

Output:

Error:(12, 21) java: float cannot be dereferenced

Here, float is a primitive data type. Its object can’t be used to call Float class method. If you do so, it will give you an error.

Example 3

  import java.lang.*;    public class Float_floatValueMethodExample3 {              public static void main(String[] args) {               //passing negative float value              float f1 = -98797987876875698796.63655768769857694f;              Float f2 =new Float(f1);              //either call floatValue() method this way              Float f3 = f2.floatValue();              System.out.println(“Float value = “+f3);                  //directly call the method in println function              Float f4= new Float(-8276372f);              System.out.println(“Float value  = “+f4);          }      }  

Test it Now

Output:

Float value = -9.879799E19  Float value  = -8276372.0
