It is a method or function that provides a default value when the actual value is null or not present. This is particularly useful in scenarios where a null value could cause a runtime error or lead to unexpected behavior.
The orDefault method is often used in conjunction with optional types, which are variables that can hold
When using orDefault, if the optional variable contains a value, that value is returned. If the optional
For example, in Java, you might use the orElse method of the Optional class to provide a
Optional<String> optionalName = Optional.ofNullable(null);
String name = optionalName.orElse("Unknown");
In this example, since optionalName is null, the variable name will be assigned the value "Unknown".
The orDefault method is a simple yet powerful tool for handling null or missing values, making code
