java - Changing the colour of energy bars depending on their values? -


i created method check value in progress bar. works expected when decreasing, i.e. turns red, yellow , orange. when increase value colour doesn't update. when it's below 25 , turns red, remains colour when increase value of energy bar. doing wrong here? in advance. 

public void checkenergybar(jprogressbar energybar){     if(energybar.getvalue()<25){         energybar.setforeground(color.red);     }else if(energybar.getvalue()<51){         energybar.setforeground(color.yellow);     }else if(energybar.getvalue()<76){         energybar.setforeground(color.orange);     }else if(energybar.getvalue()<101){         energybar.setforeground(color.green);     }       energybar.repaint();  }

i made these changes, , still no joy.

public void checkenergybar(jprogressbar energybar){     if(getenergy()<26 ){         energybar.setforeground(color.red);     }else if(getenergy()<51 || getenergy()>26){         energybar.setforeground(color.yellow);     }else if(getenergy()<76 || getenergy()>51){         energybar.setforeground(color.orange);     }else if(getenergy()<101 || getenergy()>76){         energybar.setforeground(color.green);     }       energybar.repaint();  }

personally, think jprogressbar bugged. have own, more customizable way of making progress bar.

instead of using pre-made jprogressbar, use original way of displaying graphics: canvas

create subclass of canvas, override paint method, add variables represent color , value, , add setvalue method. in paint method, set color based on value, setforeground(color), use graphics argument paint rectangle(0,0,value,getheight()).

that how make progress bar. has advantage of:
a) add border & background color canvas, progress bar
b) use graphics.paintimage , scale/crop image correct size

hopefully helped progress bar :)

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.
