Since I decided to use Java in my business,
to output basic Java usage and organize my knowledge.
MyApp.java
public class MyApp{
public static void main(String[] args){
//Calculation
int i;
i = 10 / 3;
System.out.println(i);
i = 10 % 3;
System.out.println(i);
int x = 5;
x++;
System.out.println(x);
x--;
System.out.println(x);
}
}
$ javac MyApp.java
$ java MyApp

MyApp.java
public class MyApp{
public static void main(String[] args){
//Calculation
int x = 5;
//x = x + 12;
x += 12;
System.out.println(x);
String s;
s = "hello" + "world!";
System.out.println(s);
}
}
$ javac MyApp.java
$ java MyApp

helloworld!
