Java Control Flow in Java

Control flow statements determine the order in which your code executes. Java provides if/else for branching, switch for multi-way branching, and for/while/do-while for loops.

The `if` statement evaluates a boolean expression. If true, the if-block runs; otherwise the optional `else` block runs.

A `switch` statement compares a variable against multiple constant values (called cases). Java's switch works with int, String, char, and enum types.

Java has three loop constructs: `for` (used when the number of iterations is known), `while` (used when iterations depend on a condition), and `do-while` (executes at least once, then checks the condition).

The enhanced for-each loop (`for (type item : collection)`) is ideal for iterating over arrays and collections without needing an index.

`break` exits a loop or switch immediately; `continue` skips the current iteration and moves to the next one.

// If/else
if (condition) {
    // runs if true
} else if (anotherCondition) {
    // runs if anotherCondition is true
} else {
    // fallback
}

// Switch
switch (variable) {
    case value1: doSomething(); break;
    case value2: doSomethingElse(); break;
    default: fallback();
}

// For loop
