The java.lang.Number.longValue() is an inbuilt method in java that returns the value of the specified number casted to long data type. This may involve rounding or truncation.
Syntax:
public abstract long longValue()
Parameters: This method does not accepts any parameter.
Return value: This method returns the numeric value represented by this object after conversion to type long.
Below program illustrate the Number.longValue() method:
Program 1:
// java program to demonstrate // Number.longValue() method public class gfg {
public static void main(String[] args)
{
// number as float
Float x = new Float(127483456f);
// print the value as long
System.out.println(x.longValue());
// number as double
Double y = new Double( 78549876 );
// print the value as long
System.out.println(y.longValue());
}
} |
Output:
127483456 78549876
Program 2:
// java program to demonstrate // Number.longValue() method public class gfg {
public static void main(String[] args)
{
// number as float
Float x = new Float(127f);
// print the value as long
System.out.println(x.longValue());
// number as double
Double y = new Double( 76.23 );
// print the value as long
System.out.println(y.longValue());
}
} |
Output:
127 76
