The of(int) method help us to get an OptionalInt object which contains a int value which is passed as a parameter to this method.
Syntax:
public static OptionalInt of(int value)
Parameters: This method accepts a int value as parameter that will be set to the returned OptionalInt object.
Return value: This method returns an OptionalInt with the value present.
Below programs illustrate of(int) method:
Program 1:
// Java program to demonstrate// OptionalInt.of(int) method import java.util.OptionalInt; public class GFG { public static void main(String[] args) { // Create a OptionalInt instance // using of() method OptionalInt opInt = OptionalInt.of(452); // Get value of this OptionalInt instance System.out.println("OptionalInt: " + opInt); }} |
Output:
OptionalInt: OptionalInt[452]
Program 2:
// Java program to demonstrate// OptionalInt.of(int) method import java.util.OptionalInt; public class GFG { public static void main(String[] args) { // Create a OptionalInt instance // using of() method OptionalInt opInt = OptionalInt.of(2149); // Get value of this OptionalInt instance System.out.println("OptionalInt: " + opInt); }} |
Output:
OptionalInt: OptionalInt[2149]
