For HashSet, LinkedHashSet, and EnumSet the add(), remove() and contains() operations cost constant O(1) time. Thanks to the internal HashMap implementation. Here is what the above code is Doing: 1. Create a HashSet of strings. 2. Add some strings to the HashSet. 3. Check if the HashSet contains a given string. 4. Remove a string…

Here is what the above code is Doing: 1. The tint color is set to the color resource @color/tint_color. 2. The tint mode is set to SRC_ATOP. 3. The tint is applied to the button drawable.

public static double angleDiff(double a, double b) { return ((((a – b) % 360F) + 540F) % 360F) – 180F; } Here is what the above code is Doing: 1. It’s taking the difference between the two angles. 2. It’s adding 540 to that difference. 3. It’s taking the modulus of that sum. 4. It’s…
