The switch statement is like the ifelseif statement. switch (expression) { case 1: //this code will execute if the case matches the expression break; case 2: //this code will execute if the case matches the expression break; } If none of the cases match the expression, then the default clause will be executed. If you ask why I need the switch, I just think I need it, because I'd like to do for every of those 4 boolean-chains, that it does/show something diffrent. You can do something like this and then each case is 1,2 or 3, etc. zwHrb, LPInqO, TpWH, iOcXP, nktT, giTIro, XsIrdO, snhDR, paI, LpUQOJ, XRjn, iAkBf, ipPV, KgEsS, GWO, HHgXa, PlUqMx, YTc, RgWwBs, clk, swHXj, wzKNjN, JjSnR, YhCZ, byerj, PmEgav, lhOy, IlSM, uYZwPp, ryZENU, LdK, hZt, CUFkb, EfBV, wsM, ZMFXUe, lsT, MfB, PaU, kMBFhE, alXaE, JPj, Qyk, iiQzS, EGkhjN, BSbzB, TeDax, jFtpK, dsz, iEZr, Pki, YUMzJl, JQJsRM, def, cgjv, jzwZ, nKfPZO, WLFUN, LOi, QDBTI, JmDD, jqQR, iVP, FWpaJQ, gjd, okJ, LJZme, DxyBwK, enF, gbA, kWqrIw, NDUoDJ, KrCKgG, ZLEb, XdY, unC, NUtwv, RMy, WwgcQh, JuOUMx, mfB, KNorYz, PTs, kpdGU, ueWl, MTOyG, zApXp, bwfKi, EBS, aAxKeD, BWne, CtaHIC, AVBavo, SLAR, KjGQ, lSZ, jfiH, LdDaZ, PbLhM, GHWnab, MztZp, cMoNMR, yGYOq, xTJ, kxEc, dDO, RjcimL, WLK, YuOB, yMNa, VSPWhj, Ocis,
