Number.longValue() method in java with examples
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
