Stream : Group names by Length In this Java code snippet, we’re grouping these strings by their lengths. The `groupingBy` collector organizes the strings into a map where the keys represent the lengths, and the values are lists of strings with the same length. The code snippet efficiently creates the `groupedByLength` map, which groups the…
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….
Demystifying the Java Code: Filtering Prime Numbers with Streams Have you ever encountered a piece of Java code that left you scratching your head? Fear not, for today we’re going to unravel the intricacies of a seemingly complex code snippet that filters prime numbers using Java streams. Whether you’re a seasoned programmer or just starting…
