java - confusion of array -

char[][] boardgame = new char[10][10]; // suppose create array object (char[] row : boardgame) { arrays.fill(row, 'a'); } // suppose fill row in array char '*' // , im using "enhanced" loops (int = 0; < boardgame.length; i++) { (int j = 0; j < boardgame[i].length; j++) { system.out.print("|" + boardgame[i][j] + "|"); } // in loop above isn't "i" , "j" been overwrite // numbers declare int = 0 , update if // status true i++ // how come print|*||*||*||*||*|....instead of |1||2||3|...? system.out.println(); }

in inner for loop above, "i" , "j" have been overwritten numbers, declare int = 0 , update if status true i++.

how come prints |*||*||*||*||*|... instead of |1||2||3|...?

boardgame[i][j] returns char stored @ index j in dimension í, , since have filled entire array asterisks, printed. if want print numbers, replace boardgame[i][j] j

i suggest read this documentation details on how arrays work.
