Hello, My name is Arnav, and I am a 14-year-old developer who is interested in contributing to the OpenJDK. I would like to propose adding a set of "contains" methods to the java.util.Arrays class. Currently, to check if a primitive array (like char or int) contains a specific value needs a large manual for loop, converting to a List, or using a very complicated Stream pipeline. My idea proposes adding a series of static "contains" methods for all 8 primitive types to java.util.Arrays public static boolean contains(char[] a, char key) public static boolean contains(int[] a, int key) public static boolean contains(byte[] a, byte key) public static boolean contains(short[] a, short key) public static boolean contains(long[] a, long key) public static boolean contains(float[] a, float key) public static boolean contains(double[] a, double key) public static boolean contains(boolean[] a, boolean key)
Why should you consider this proposal? Arrays.contains(myChars, 'a') is much more readable than workarounds like a for loop. For newer Java learners, not having a "contains" method on arrays is very confusing when you compare it to other languages like Python. If this proposal is viewed favorably, I am willing to make all of the 8 primitive overloads and any of the corresponding unit tests. I am also looking for a sponsor to help me navigate the OCA process for minors and guide me through the technical process of pushing these changes. I look forward to your feedback on whether this is a direction the Core Libs group would support. Thank you so much for considering my idea and reading through this email, your support means a lot to me! Thank you, Arnav
