Variable hiding

Scenario where local variable in a method or constructor has the same name as an instance variable or a class variable is known as variable hiding (i.e. local variable hides the instance variable or class variable).

public class Main {

  private String text = "outer variable";

  public Main() {
    String text = "constructor variable";
    System.out.println(text);
  }

  public void localVariable() {
    String text = "local variable";
    System.out.println(text);
  }

  public void instanceVariable() {
    String text = "instance variable";
    System.out.println(this.text);
  }
}

Local variables within the constructor and methods hide the instance variable instance text.
