Getting float Value from Float Object having Positive Value Example

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

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

Output

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

Value = 15.3

Getting float Value from Float Object having Negative Value Example

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

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

Output

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

Value = -15.3

Getting float Value from Float Object having Negative Zero Value Example

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

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

Output

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

Value = -0.0

Getting float Value from Float Object having Positive Zero Value Example

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

package com.tutorialspoint;
public class FloatDemo {
   public static void main(String[] args) {

      Float f = new Float("+0.0");
   
      //return the float value
      System.out.println("Value = " + f.floatValue()); 
   }
} 

Output

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

Value = 0.0
