How to use setters, also known as set methods or mutators, in Java. In this video I also take a look at the ‘this’ keyword and when to use it.

When the video is running, click the maximize button in the lower-right-hand corner to make it full screen.

Code for this tutorial:

class Frog {
	private String name;
	private int age;
	
	public void setName(String name) {
		this.name = name;
	}
	
	public void setAge(int age) {
		this.age = age;
	}
	
	public String getName() {
		return name;
	}
	
	public int getAge() {
		return age;
	}
	
	public void setInfo(String name, int age) {
		setName(name);
		setAge(age);
	}
}

public class App {

	public static void main(String[] args) {
	
		Frog frog1 = new Frog();
		
		//frog1.name = "Bertie";
		//frog1.age = 1;
		
		frog1.setName("Bertie");
		frog1.setAge(1);
		
		System.out.println(frog1.getName());
	}

}
