This article presents variable naming convention in Java.

Class formatting

Edit

new line before main method,
new line before if statements / loops

Array of integers example

Edit

xxxxxxxxxx
 
import java.util.Arrays;
​
public class Example {
​
    public static void main(String[] args) {
        int[] numbers = {1, 2, 3};
        System.out.println(Arrays.toString(numbers));
    }
}

Array of Strings example

Edit

xxxxxxxxxx
 
import java.util.Arrays;
​
public class Example {
​
    public static void main(String[] args) {
        String[] letters = {"a", "b", "c"};
        System.out.println(Arrays.toString(letters));
    }
}

Array of Objects example

Edit

Example user object:

xxxxxxxxxx
 
public class User {
    private final String name;
    private final int age;
​
    public User(String name, int age) {
        this.name = name;
        this.age = age;
    }
​
    public String getName() {
        return name;
    }
​
    public int getAge() {
        return age;
    }
​
    @Override
    public String toString() {
        return "User{ " +
                "name='" + name + '\'' +
                ", age=" + age +
                " }";
    }
}

Array of objects:

xxxxxxxxxx
 
import java.util.Arrays;
​
public class Example {
​
    private static int[] myArray = {1, 2, 3};
​
    public static void main(String[] args) {
        User[] users = {new User("Tom", 19), new User("Kate", 21)};
​
        System.out.println(Arrays.toString(users));
    }
}
