What are blocks in Java programming?

Blocks in Java programming are defined by a pair of braces { }. They are used to group statements together so that they can be treated as a single unit. This grouping allows for better structure in the code and makes it easier to manage the scope of variables, control flow statements, and other constructs.

For example, when defining a method, the lines of code inside the method are enclosed within braces. This helps the compiler understand the boundaries of the method. Similarly, blocks are used in control flow statements like if-else conditions, loops (for, while), and in class and interface definitions.

The use of blocks not only enhances readability but also clarifies where variables are accessible and helps avoid naming conflicts. Understanding how to properly use blocks is essential for organizing code effectively in Java programming, leading to more maintainable and organized codebases.
