java - Count the number of “trues” for n booleans -

public static boolean startrack[][][] = { {{true,true,true}, {true,true,true}, {false,false,false}, {false,false,false}, {false,false,false}, {false,false,false}, {false,false,false}, {false,false,false}, {false,false,false}, {false,false,false}}, {{false,false,false}, {false,false,false}, {false,false,false}, {false,false,false}, {false,false,false}, {false,false,false}, {false,false,false}, {false,false,false}, {false,false,false}, {false,false,false}}, {{false,false,false}, {false,false,false}, {false,false,false}, {false,false,false}, {false,false,false}, {false,false,false}, {false,false,false}, {false,false,false}, {false,false,false}, {false,false,false}}, {{false,false,false}, {false,false,false}, {false,false,false}, {false,false,false}, {false,false,false}, {false,false,false}, {false,false,false}, {false,false,false}, {false,false,false}, {false,false,false}} };

i want know how count number of trues in array using java. "i have array , want count number of trues. how can this?"

if understand you, -

int count = 0; (boolean[][] barrarr : startrack) { (boolean[] barr : barrarr) { (boolean b : barr) { if (b) { count++; } } } } system.out.println(count);

given startrack output of

6
