javaCopy code

public class Car { // Fields (data) String brand; int year; // Methods (behavior) void start() { System.out.println("The car is starting."); } void drive() { System.out.println("The car is moving."); } }

3. Control Flow Statements:

Control flow statements, such as if, else, for, and while, allow you to control the flow of execution in your Java programs. Mastering these statements is crucial for writing efficient and logic-driven code.

javaCopy code

int num = 10; if (num > 0) { System.out.println("The number is positive."); } else { System.out.println("The number is non-positive."); }
