In this example, we are going to learn how to find string is palindrome or not using stream. Steps to solve this problem : 1. First we will iterate string by half of its size 2. We will compare each character so here we are comparing ith element with (length-i-1)th element if all matches then…
In this example, we will learn how we can find first non-repeated character using stream so first we will go oversteps how to solve this problem. Step 1: Iterate all the character from input stream Step 2: Now we will count character occurrence and will store this result into LinkedHashMap, why we have used…
In this blog, We are going to discuss basic git commands : 1. git init This command will create a new Git repository in the current directory and it will create a `.git` folder where version control information is stored. 2. git clone <repository> This command will create a local copy of a remote repository…
How to extract initials using stream in java In this Java code snippet, a list of strings named `names` is created, containing full names like “John Doe,” “Jane Smith,” and “Alice Johnson.” Using Java 8 streams, a new list called `initials` is generated by applying a transformation to each full name in the `names` list….
How to Convert temperature using stream in java In this Java code snippet, a list of double values named `celsiusTemps` is created, containing temperatures in Celsius: 0.0, 10.0, 20.0, and 30.0. Using Java 8 streams, a new list called `fahrenheitTemps` is generated by applying a conversion formula to each Celsius temperature. The `map` operation transforms…
How to check Palindrome in java using Stream API In this Java code snippet, a list of strings named `words` is created, containing “radar,” “hello,” and “deified.” Using Java 8 streams, a new list called `palindromes` is generated by filtering the `words` list. The `filter` operation checks if a string is a palindrome by comparing…
How to sum even numbers with Reduce in java In this Java code snippet, a list of integers named `numbers` is created with values 2, 4, 6, 8, and 10. Using Java 8 streams, the code calculates the sum of even numbers from the `numbers` list. The `filter` operation selects only even integers by checking…
How to filter strings via length using stream in java In this Java code snippet, a list of strings named `words` is created, containing “apple,” “banana,” “cherry,” and “date.” Utilizing Java 8 streams, a new list called `longWords` is generated by filtering the `words` list. The `filter` operation selects only those strings from the original…
Calculate factorial using stream in java ? In this Java code snippet, an integer variable `n` is set to 5. Using Java 8 streams, the code calculates the factorial of `n`. It does this by generating a range of integers from 1 to `n` (inclusive), and then reducing them using a multiplication operation. The `reduce`…
Stream : Summing Values in a Map In this Java code snippet, a `Map` called `scores` is created to store name-score pairs. Two entries are added for “Alice” with a score of 90 and “Bob” with a score of 85. The subsequent lines utilize Java 8 streams to extract the values (scores) from the `scores`…
