Comparisons

Understanding Comparisons in Programming

In programming, comparisons are fundamental operations used to evaluate relationships between values. They allow a program to make decisions, control the flow of execution, and implement logic based on specific conditions. Essentially, comparisons answer questions like “Is this value equal to that value?” or “Is this number greater than that number?”

Comparisons are used extensively in conditional statements, loops, and algorithms. They are at the heart of decision-making in code.

Comparisons with Strings and Objects

While numeric comparisons are straightforward, comparisons with strings and objects can be more nuanced. For example, in Java, comparing two strings with == checks whether the two variables reference the same object, not whether the text inside is identical. To compare the actual content of strings, you must use methods like .equals().
