---

---

Description

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

Declaration

Following is the declaration for java.lang.Double.floatValue() method

public float floatValue()

Parameters

NA

Return Value

This method returns the float value represented by this object.

Exception

NA

Example 1

The following example shows the usage of Double floatValue() method to get a float primitive value of given positive Double object. We've initialized a Double object with a given positive float value. Then using floatValue() method, we're printing its value.

package com.tutorialspoint;
public class DoubleDemo {
   public static void main(String[] args) {
      Double d = new Double("15.30");
   
      //return the float value
      System.out.println("Value = " + d.floatValue());
   }
} 

Output

Let us compile and run the above program, this will produce the following result −

Value = 15.3

Example 2

The following example shows the usage of Double floatValue() method to get a float primitive value of given negative Double object. We've initialized a Double object with a given positive float value. Then using floatValue() method, we're printing its value.

package com.tutorialspoint;
public class DoubleDemo {
   public static void main(String[] args) {
      Double d = new Double("-15.30");
   
      //return the float value
      System.out.println("Value = " + d.floatValue());
   }
} 

Output

Let us compile and run the above program, this will produce the following result −

Value = -15.3

Example 3

The following example shows the usage of Double floatValue() method to get a float primitive value of given negative Double object of zero value. We've initialized a Double object with a given positive float value. Then using floatValue() method, we're printing its value.

package com.tutorialspoint;
public class DoubleDemo {
   public static void main(String[] args) {
      Double d = new Double("-0.0");
   
      //return the float value
      System.out.println("Value = " + d.floatValue());
   }
} 

Output

Let us compile and run the above program, this will produce the following result −

Value = -0.0

Example 4

The following example shows the usage of Double floatValue() method to get a float primitive value of given positive Double object of zero value. We've initialized a Double object with a given positive float value. Then using floatValue() method, we're printing its value.

package com.tutorialspoint;
public class DoubleDemo {
   public static void main(String[] args) {
      Double d = new Double("+0.0");
   
      //return the float value
      System.out.println("Value = " + d.floatValue()); 
   }
} 

Output

Let us compile and run the above program, this will produce the following result −

Value = 0.0
