 Dibawah adalah kod lazyloading untuk membuatkan blog loading lebih laju lalu untuk mendapat score lebih tinggi di Google PageSpeed Insights. Cara memasangnya adalah seperti berikut 1. Copy kod dibawah <script> //<![CDATA[ //Lazy Load (function(a){a.fn.lazyload=function(b){var c={threshold:0,failurelimit:0,event:"scroll",effect:"show",container:window};if(b){a.extend(c,b)}var d=this;if("scroll"==c.event){a(c.container).bind("scroll",function(b){var e=0;d.each(function(){if(a.abovethetop(this,c)||a.leftofbegin(this,c)){}else if(!a.belowthefold(this,c)&&!a.rightoffold(this,c)){a(this).trigger("appear")}else{if(e++>c.failurelimit){return false}}});var f=a.grep(d,function(a){return!a.loaded});d=a(f)})}this.each(function(){var b=this;if(undefined==a(b).attr("original")){a(b).attr("original",a(b).attr("src"))}if("scroll"!=c.event||undefined==a(b).attr("src")||c.placeholder=

Grafical User Interface(GUI) Berenteraksi dengan program visual code: import javax.swing.JOptionPane; public class main { public static void main(String[] args) { String name = JOptionPane.showInputDialog("enter your name"); } } mari tambah lagi satu kod supaya dia dapat berenteraksi sama kita: import javax.swing.JOptionPane; public class main { public static void main(String[] args) { String name = JOptionPane.showInputDialog("enter your name"); JOptionPane.showMessageDialog(null,"Hello"+name); } } Tonton video selanjutnya tentang GUI

 public class main { public static void main(String[] args) { //expression =  operands & operators //operands = values, variables, numbers & quantity //operators = + - * / % int friends = 10; friends = friends *2; System.out.println(friends); } } console output: 20 example 2:                 int friends = 10; friends = friends +3; System.out.println(friends); console input: 13 nota: jika mahu dapat hasil bahagi(/) yang tepat gantikan int kepada double contoh:               int friends = 10; friends = friends /3; -------------------------------------- console output: 3 -------------------------------------- jadi, gantikan kepada double contoh:                         double friends = 10;                   friends = friends /3; ---------------------------------- console output:                        3.3333333333333335 ---------------------------------

Scanner digunakan untuk menerima input pengguna ---------------------------------------- import java.util.Scanner; public class main { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); System.out.println("what is your name?"); String name = scanner.nextLine(); System.out.println("hello "+name); } } console output what is your name? console akan pause ketika ini sehingga anda taip nama awak dan tekan enter console output: what is your name? mamat hello mamat contoh lain: import java.util.Scanner; public class main { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); System.out.println("what is your name?"); String name = scanner.nextLine(); System.out.println("how old are you"); int age = scanner.nextInt(); System.out.println("hello "+name); System.out.println("your age"+age+"years old&quo

 public class main { public static void main(String[] args) { String x="water"; String y="cool-aid"; System.out.println("x: "+x); System.out.println("y: "+y ); } } console output x: water y: cool-aid perkenalkan(tambah) satu lagi variable iaitu temp public class main { public static void main(String[] args) { String x="water"; String y="cool-aid"; String temp; temp = x; x = y; y=temp; System.out.println("x: "+x); System.out.println("y: "+y ); } } console output x: cool-aid y: water
