You can declare a final variable and later initialize it. true or false?
You can declare a final variable and later initialize it. true or false? Please explain
That statement is true. When you declare a variable with the
final keyword it cannot be reassigned (be given a new value) after it has been assigned. But you can leave it empty during the declaration and provide it with it's value later.
final String example = "Hello World!"; // Creates a final String set to "Hello World" example = "Hello!" // This is invalid since the example variable has already been set to "Hello World!"
final String example; // Creates an empty final String example = "Hello!" // This is valid since the example variable has not been assigned a value yet. example = "Hello World" // This is invalid since the example variable has already been set to "Hello!"
