U - Unit Testing
Used to verify individual parts of code (methods, classes) using tools like JUnit or TestNG. Ensures each part works correctly in isolation.
V - Variables
Containers for storing data values. Java supports:
Instance variables
Static variables
Local variables
Parameters
W - Wrapper Classes
Provide object versions of primitive data types. E.g., int โ Integer, double โ Double. Useful when working with collections or for autoboxing.
X - XML (eXtensible Markup Language)
Used to store and transport data. In Java, XML is commonly used for configuration (e.g., Spring) and data interchange.
Y - Yield (Threading)
The Thread.yield() method hints to the scheduler that the current thread is willing to yield its current use of a processor.
Z - Zero-Based Indexing
Java arrays and collections are zero-indexed, meaning the first element is accessed at index 0.
int[] arr = {1, 2, 3};
System.out.println(arr[0]); // Outputs 1
