Need help to explain seats at a cinema program made in java -

can please me understand going on here? find hard understand whats going on these multidimentional arrays. if explain me in detail program does. i'm supposed find first available seat @ movie theatre. program terminate first seat.

public class cinema {     private boolean[][] seats = {{ true, true, false, false, false, true, true false},                              { true, true, true, true, true, true, true, true},                              { true, true, true, true, true, true, true, true}}    public void findavailable() {      boolean found = false;      int row = 0;     while (!found && row < seats.length) {         int seat = 0;         while (!found && seat < seats[row].length) {           if (seats[row][seat]) {             found = true;             system.out.println("row = " + row + " seat = " + seat);           }           seat++;         }         row++;     } } 

a movie theater way explain 2 dimensional array.

boolean[][] seats =  {{true, true, false, false, false, true, true false},  {true, true, true, true, true, true, true, true},  {true, true, true, true, true, true, true, true}  } 

you see every row in array row of seats. can use first seat seats[0][0], or second seat on first row seats[0][1]. in order go through seats on first row, can make loop:

for(x = 0; x < 8; x++){     system.out.println("the boolean value of seat " + x + " on first row is: " + seats[0][x]); } 

now can search second row (keep in mind index of array starts @ 0) seats[1][x]

now, if loop through possible seats, have make 2 loops: 1 loop through number of seat , 1 loop through rows:

for(y = 0; y < 3; y++){     for(x = 0; x < 8; x++){         system.out.println("the boolean value of seat " + x + " on row "+ y + " is: " + seats[y][x]);     } } 

note cannot loop further size of array (3 rows , 8 seats). why using .length attribute determine size.

now thing find first seat available, loop through array once again , when boolean value @ particular seat true, have break out of both of loops. why there boolean variable found, set true when seat found , causes loop not execute again (note ! in while condition).
