How Aliasing affects Java's reference variable ?.

Program to demonstrate how aliasing affects Java's reference variable

class Triangle {
 
  public int width;
 
}

public class AliasingEffect {
 
  public static void triangleAlias(Triangle triangle){
  
    triangle.width = 20;
  
  }
 
  public static void main(String[] args) {
  
    Triangle triangleOne = new Triangle();
    triangleOne.width = 10;
  
    System.out.println("1: triangleOne's width = " + triangleOne.width);
  
    triangleAlias(triangleOne);
  
    System.out.println("2: triangleOne's width = " + triangleOne.width);

  }

}
