Why is `1 == 1` True but, `1000 == 1000` False in Java?

In this video, we'll tackle a common Java interview question: Why does 1 == 1 evaluate to true while 1000 == 1000 evaluates to false when dealing with Integer objects? We'll dive into Java's wrapper classes, object caching, and the behavior of the == operator. By the end, you'll understand the subtleties behind these comparisons and how Java optimizes memory and performance through caching. This knowledge is crucial for writing efficient and bug-free code in Java.
