Below programs illustrate java.lang.Integer.doubleValue() method.
Program 1:
// Code to illustrate doubleValue() method import java.lang.Integer;
class Gfg {
// Driver code public static void main(String args[])
{
Integer a = new Integer( 14 );
// Convert Integer number to double value
double b = a.doubleValue();
System.out.println(b);
}
} |
Output:
14.0
Program 2:
// Code to illustrate doubleValue() method import java.lang.Integer;
class Gfg {
// Driver code public static void main(String args[])
{
Integer a = new Integer( 120 );
// Convert Integer number to double value
double b = a.doubleValue();
System.out.println(b);
}
} |
Output:
120.0
