Java string.format() only half working -

-

i trying construct string using string.format(), stops working (just over) half way through.

private string constructmessage(string messagetype, int messagecode,position location) {     double lat = location.getlat();     double lon = location.getlon();     double ele = location.getele();     double speed = 0.0;     double heading = 0.0;      string msg = "$pngvest," + messagetype + "," + vest_id + ","             + system.currenttimemillis() + "," + lat + "," + lon + "," + ele             + "," + speed + "," + heading + "," + messagecode;      string test = string.format("$pngvest,%s,%d,%d,%f,%f,%f,$f,$f,$d",             messagetype, vest_id, system.currenttimemillis(), lat, lon, ele,             speed, heading, messagecode);      system.out.println(msg);     system.out.println(test);     return msg; }

when run above code, following output:

$pngvest,location,1,1439998967553,51.558641765246364,-3.043043462354341,-1.0,0.0,0.0,0 $pngvest,location,1,1439998967553,51.558642,-3.043043,-1.000000,$f,$f,$d $pngvest,location,1,1439998968553,51.55862560874394,-3.043027770590568,-1.0,0.0,0.0,0 $pngvest,location,1,1439998968553,51.558626,-3.043028,-1.000000,$f,$f,$d

why not format last 3 variables?

you made typo's last 3 variables. noted $f , $d instead of %f , %d.

it should :

string test = string.format("$pngvest,%s,%d,%d,%f,%f,%f,%f,%f,%d",         messagetype, vest_id, system.currenttimemillis(), lat, lon, ele,         speed, heading, messagecode);

instead of

string.format("$pngvest,%s,%d,%d,%f,%f,%f,$f,$f,$d", ...);
