java - How to use a variable in two classes? -


i need able see in of these classes if variable true.

    public void performaction() {     if (door.intersects(hero)) {         system.out.println("actionperformed!");         herox = 0;         heroy = 0;         inside = true;         }     }

this every time press space , want draw inside of house. in main class draw want like:

    public void paintcomponent(graphics g) {     if (!inside) {         g.drawimage(background, 0, 0, null);         achilles.draw(g);     }else if (inside) {         g.drawimage(houseinside, 0, 0, null);          }     }

i don't know how change "inside" in hero class , use in main class. have tried many things , don't know do.

inside property of hero object, so, if property public, can access heroname.inside

if property private (which should be), have use public access function inside hero class, such hero.isinside, , set setting function hero.setinside , hero.setoutside.

this called "getters , setters"

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
