Control structures in Java dictate the flow of program execution and are divided into three main categories: 1. Sequential Execution—The default behavior where statements are executed line by line. 2. Selection (Decision-Making) Statements—Used for conditional execution: if—Executes a block if a condition is true. if-else—Executes one block if true, another if false. switch—Selects a block based on a variable’s value. 3. Iteration (Looping) Statements—Repeats a block of code: for – Runs a loop a fixed number of times. while – Runs as long as the condition is true. do-while – Executes at least once before checking the condition. 4. Jump Statements– Controls loop execution and method returns: break – Exits a loop or switch statement. continue – Skips the current iteration and moves to the next. return – Exits from a method, optionally returning a value.
