java - Getting Percentages in Progress Bar -


i working on program, there progress bar on side. i'm stumped on seeing if users level (a double), 10 - 100% complete. example, if goal 10, display percentage, not 39%, every tenth of number. thanks, export.

cast level int.

use / integer division 10, yielding 0, 1, 2 .. 10. multiply 10 0, 10, 20 .. 100.

double level = ... ; // level between 0.0 , 100.0 inclusive.

int progressbarvalue = ((int)level / 10) * 10;
