How to represent property in UML class diagram

public class Example {
  private int x;
  protected int y;
  public int z;
  public Example() { ... }
  public String toString() { ... }
  private void foo(int x) { ... }
  protected int bar(int y, int z) { ... }
}

-x:int    // -x represent x integer variable which is private(-)
#y:int // #y represent y interger variable which is protected(#)
+z:int // +z represent z interger variable which is public(+)

+<<constructor>>Example() // Same Name so represent as Constructor and + represent Public
