"this" -> "me/myself/I" 🙋🏽

"this" means the current object we are coding in.

Student
Coding in "Student", "this" is Student.
Planet
Coding in "Planet", "this" is Planet

public class 1Student {

	private String firstName;
	private String lastName;
	private int credits;

	public void foo() {
		2CODING HERE
	}
} //end Student




public class 3Planet {

	String name;
	int radius;		//miles

	public void foo() {
		4CODING HERE
	}
}

Example #1

We are coding in Person. Thus, "this" is "Person"
Person" has ivar "firstName
Accessing Person's ivar "firstName" using "this"

NOTE WELL -- Learn little by little... 👍🏽

public class 1Person {

	private String 2firstName;
	private String lastName;

	public Person(String aFirstName, String aLastName) {
		3this.firstName = aFirstName;
		this.lastName = aLastName;
	}

Example #2

We are coding in Person. Thus, "this" is "Person"
Person" has instance method "getFullName
Accessing Person's method "getFullName" using "this"

public class 1Person {

	private String firstName;
	private String lastName;

	public Person(String aFirstName, String aLastName) {
		this.firstName = aFirstName;
		this.lastName = aLastName;
	}

	public void setNames(String aFirstName, String aLastName) {
		this.firstName = aFirstName;
		this.lastName = aFirstName;
	}

	public String 2getFullName() {
		String fullName;
		fullName = this.firstName + " " + lastName;
		return fullName;
	}

	public String toString() {
		return "Person: " + 3this.getFullName();
	}

}
