Java statements are the core instructions in Java programming, enabling variable declarations, method invocations, and controlling execution flow. They are categorized into declaration, expression, and control flow statements, each with a specific role. Conditional statements like if-else and switch, along with looping constructs such as while and for loops, are crucial for decision-making and automating repetitive tasks in Java applications.

Declaration statements introduce new variables and define their data types
Expression statements perform actions, such as assigning values, invoking methods, or applying operators
Control flow statements enable conditional or iterative execution of code segments
The if statement executes a block of code when its condition is true
The if-else statement adds an alternative path when the condition is false
The switch statement provides a streamlined approach to handling multiple potential values of a single variable
The while loop continues to execute as long as its condition remains true
The for loop is used for repeatedly executing code blocks for a specific number of iterations
The do-while loop executes the code block at least once before checking the condition for further iterations
