Stream: Remove duplicates from List In this Java code snippet, we’re dealing with a list of integers: 1, 2, 2, 3, 4, 4, and 5. Using streams, we’re filtering out duplicate values, resulting in a list of distinct numbers. The `distinct` operation ensures that each value appears only once in the resulting list. The code…
Stream: Finding Average Length In this Java code snippet, we’re working with a list of strings: “apple,” “banana,” and “cherry.” Using streams, we transform each string into its corresponding length and convert it to an integer. Then, we calculate the average of these lengths. If the list is empty, the `orElse` function sets the average…
Summing Even Indices using Streams Here we’re performing a series of operations on a list of integers. The `numbers` list contains 10, 20, 30, 40, and 50. Using streams, we start by filtering the indices that are even. Then, we map these indices to their corresponding values in the `numbers` list. Finally, we calculate the sum…
Combining Strings with Delimiter using stream We’re merging a list of strings into a single string using streams. The `words` list contains “Hello,” “world,” and “Java.” By applying the `joining` collector with a space delimiter, the elements are combined into the string `combined`, resulting in “Hello world Java.” Streams. make this process efficient and concise….
