How to filter empty values in Java stream?

In Java, you can use the filter() method of stream flow to filter out null values. The specific steps are as follows:

1. First, create a stream with empty values.
2. Create a stream of strings containing “apple”, an empty string, “banana”, null, and “orange”.
3. Next, use the filter() method to remove empty values.
4. Create a filtered stream of strings by removing any null or empty strings.
5. Finally, utilize the forEach() method to iterate over the filtered stream and perform the necessary actions.
6. Print each element in the filteredStream using a lambda expression.

The above code will produce:

apple
banana
orange

In the filter() method, a lambda expression is used to determine if a string is empty. By selecting non-empty strings, the function of filtering out empty values can be achieved.
