In java 'this' is a keyword, basically used to refer to the current object. In the following example the setter methods are using 'this' to set the values of name and age of current object.

public class Person {

  String name;
  int age;

  public String getName() {
    return name;
  }

  public void setName(String name) {
    this.name = name;
  }

  public int getAge() {
    return age;
  }

  public void setAge(int age) {
    this.age = age;
  }

  public static void main(String[] args) {
    Person p = new Person();
    p.setName("Rishi");
    p.setAge(23);
    System.out.println(p.getName() + " is " + p.getAge() + " years old");
  }
}
