OptionalInt toString() method in Java with examples
The toString() method help us to get a non-empty string representation of this OptionalInt.This non-empty string representation is suitable for debugging. The exact presentation format is unspecified and may vary between implementations and versions.
Syntax:
public String toString()
Parameters: This method accepts nothing.
Return value: This method returns the string representation of this instance.
Below programs illustrate toString() method:
Program 1:
import java.util.OptionalInt;
public class GFG {
public static void main(String[] args)
{
OptionalInt opInt
= OptionalInt.of( 452146 );
String value = opInt.toString();
System.out.println( "String Representation: "
+ value);
}
}
|
Output:
String Representation: OptionalInt[452146]
Program 2:
import java.util.OptionalInt;
public class GFG {
public static void main(String[] args)
{
OptionalInt opInt
= OptionalInt.empty();
String value = opInt.toString();
System.out.println( "String Representation: "
+ value);
}
}
|
Output:
String Representation: OptionalInt.empty
