"Halo, Amigo."

"Halo, Eleanor Carrey."

"Sebut wae aku Ellie. Ora perlu formal banget."

"Oke, Ellie."

"Aku yakin kanthi bantuanku, sampeyan bakal dadi salah siji sing paling apik. Aku duwe akeh pengalaman latihan wong anyar. Tetep karo aku, lan kabeh bakal apik. Ayo, ayo miwiti."

"Ana rong jinis utama ing Jawa : String lan int . Kita nyimpen strings/teks ing String, lan integers (nomer wutuh) ing int. Kanggo mratelakake variabel anyar, sampeyan kudu nemtokake jinis lan jeneng sawijining. Jeneng ora bisa dadi padha karo jeneng variabel lan/utawa fungsi liyane."

Tuladha 1, kode: Katrangan
String s;
Variabel anyar sdiumumake. Bisa nyimpen teks.
int i;
Variabel anyar i, diumumake. Bisa nyimpen integer.

"Sampeyan bisa nemtokake nilai kanggo variabel nalika sampeyan ngumumake."

Tuladha 2, kode: Katrangan
String s = "Ellie";
Variabel snyimpen string "Ellie".
int i = 5;
Variabel inyimpen nomer 5.

"Kanggo nemtokake nilai anyar kanggo variabel, kita nggunakake tandha =. Iki uga disebut 'operator penugasan' . Assignment tegese kanggo nyelehake menyang variabel nilai saka variabel liyane utawa siji diitung saka sawetara variabel. "

Tuladha 3, kode: Katrangan
int a = 5;
Variabel anyimpen nilai 5.
int b = 6;
Variabel bnyimpen nilai 6.
int c = a + b;
Variabel cnyimpen nilai 11.

"Nilai variabel bisa digunakake kanggo ngitung nilai anyar sing bakal ngganti sing lawas."

Tuladha 4, kode: Katrangan
int a = 2;
Saiki apadha karo 2
int b = 3;
Saiki bpadha karo 3
a = a + b;
Saiki apadha karo 5
b = b + 1;
Saiki bpadha karo 4

"Sampeyan bisa nggabungake string karo +tandha:"

Tuladha 5, kode: Katrangan
String s1 = "Rain";
String s2 = "In";
String s3 = s1 + s2 + "Spain";
Variabel s3nyimpen senar"RainInSpain"

"Kadhangkala, string sing dumadi saka siji utawa luwih spasi bisa migunani:"

Tuladha 6, kode: Katrangan
String s1 = "My favorite movie is";
String s2 = "Route";
int roadNumber = 66;
String text = s1 + " " + s2 + " " + roadNumber;
texttoko"My favorite movie is Route 66"

"Ayo deleng carane nampilake teks lan variabel ing layar:"

Ngenalake ints lan String - 1
Tuladha 7, kode:
1
System.out.println("A man's gotta do what a man's gotta do");
2
String s = "A man's gotta do what a man's gotta do";
System.out.println(s);

"Oalah, Diego njaluk aku menehi sawetara latihan:"

CodeGym. Learn once - use anywhere
Here's a riddle: "Written once, it runs everywhere". Answer: A Java program. That's the right answer, because Java is logical and properly structured. Let's rephrase this slogan for students: "learn once, use anywhere!" Here's a little task on this topic: write a program that displays a useful phrase 10 times on the screen.

Uh... Happy New Year!
What if you don't abandon your studies? What if you keep on completing tasks and working through the lessons? If you do, then by next New Year's, which is at least three months away, you can celebrate the new year as a real programmer! That's the dream. But for now, let's go to work. Let's remove the unnecessary comments and display some New Year's well-wishes.

Let's change the code
Editing someone else's code is sometimes more difficult than writing your own. You can trust the experience of experts at the secret CodeGym center. That's why our curriculum includes tasks about fixing code. For now, let's open our textbook, wrap our brains around some simple code, and then change the code so that the variable name takes the value "Amigo".

A few more corrections
Articles such as "1001 Tips for Becoming a Great Programmer" almost always include a phrase like "Someone else's code will teach you how to write your own". A programmer seldom works alone, so this advice is the plain truth. You won't get anywhere by ignoring it. We have to get used to teamwork and fixing other people's code.
