Java Programming Basics

Front

public

Back

This keyword means that the method can be accessed from anywhere in your program. Example: Like a public notice board in a school.

Front

static

Back

This means the method belongs to the class itself, not to any object you create from the class. Example: Like a general instruction on a blueprint.

Front

void

Back

This tells Java that the method does not return any value. Example: Like turning off the lights without getting anything back.

Front

main

Back

This is the name of the method that Java looks for when it starts running a program. Example: Like the starting point in a board game.

Front

String[] args

Back

This is a parameter for the method, an array of Strings for command-line arguments. Example: Like special instructions when ordering food.

Front

Method in Java

Back

A block of code that performs a specific task. Example: Like a recipe in a cookbook.

Front

Object in Java

Back

A thing you create from a class, allowing you to use the variables and methods defined in that class. Example: Like a house built from a blueprint.

Front

Example of a Simple Method

Back

public static void sayHello() { System.out.println("Hello, students!"); }

Front

Example of Method with Parameters

Back

public static void addNumbers(int a, int b) { int result = a + b; System.out.println("Sum is: " + result); }

Front

Example of Class and Object with Methods

Back

public class Car { String color; public void startEngine() { System.out.println("The " + color + " car engine is starting..."); } }
