Getting float Value from an Integer Having Positive Value Example

The following example shows the usage of Integer floatValue() method to get float value from an Integer object. We've created a Integer variable and assign it a Integer object containing a positive integer number. Then using floatValue method, we're obtaining the float value from this object and then printed it.

package com.tutorialspoint;
public class IntegerDemo {
   public static void main(String[] args) {
      Integer obj = new Integer(5);
 
      // returns the value of this Integer as a float
      float f = obj.floatValue();
      System.out.println("Value of f = " + f);
   }
}

Output

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

Value of f = 5.0

Getting float Value from an Integer Having Negative Value Example

The following example shows the usage of Integer floatValue() method to get float value from an Integer object. We've created a Integer variable and assign it a Integer object containing a negative integer number. Then using floatValue method, we're obtaining the float value from this object and then printed it.

package com.tutorialspoint;
public class IntegerDemo {
   public static void main(String[] args) {
      Integer obj = new Integer(-5);
 
      // returns the value of this Integer as a float
      float f = obj.floatValue();
      System.out.println("Value of f = " + f);
   }
}

Output

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

Value of f = -5.0

Getting float Value from an Integer Having Zero Value Example

The following example shows the usage of Integer floatValue() method to get float value from an Integer object. We've created a Integer variable and assign it a Integer object containing a zero value. Then using floatValue method, we're obtaining the float value from this object and then printed it.

package com.tutorialspoint;
public class IntegerDemo {
   public static void main(String[] args) {
      Integer obj = new Integer(0);
 
      // returns the value of this Integer as a float
      float f = obj.floatValue();
      System.out.println("Value of f = " + f);
   }
}

Output

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

Value of f = 0.0

Getting float Value from an Integer Having Negative Zero Value Example

The following example shows the usage of Integer floatValue() method to get float value from an Integer object. We've created a Integer variable and assign it a Integer object containing a negative zero value. Then using floatValue method, we're obtaining the float value from this object and then printed it.

package com.tutorialspoint;
public class IntegerDemo {
   public static void main(String[] args) {
      Integer obj = new Integer(-0);
 
      // returns the value of this Integer as a float
      float f = obj.floatValue();
      System.out.println("Value of f = " + f);
   }
}

Output

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

Value of f = 0.0
