Random acces to matrix using seed in Java -

how can access matrix (int[][] matrix) using random (with seed)?

i want print matrix randomly.

how use seed , random methods? can give me example?

seed is important. want write once.

int[][] matrix = ini();  // print matrix randomly using seed...? 

set seed of random instance

random rand = new random(seed); 

you can inclusive random value calling nextint method...

int row = rand.nextint(matrix.length); 

...and use these values access matrix:

int val = matrix[row][otherrandomvalue]; 

to print matrix randomly, need loop on length of row , column. avoid duplicate values, can keep set of indexes (such using java.awt.point class) , check set see if value has been used yet

set<point> uniques = new hashset<point>();  ( int = 0; < matrix.length; i++ ){//loop on rows     ( int j = 0; j < matrix[i].length; j++ ){         point p = new point(rand.nextint(matrix.length), rand.nextint(matrix[i].length));         while ( uniques.contains(p) ){             p = new point(rand.nextint(matrix.length), rand.nextint(matrix[i].length));         }         uniques.add(p);         //p.x , p.y contain indexes     } }
