Finding the maximum integer value contained in a matrix using Java -

to find maximum integer value in matrix try code of that:

/*  * @param ints  * @return max value in array of chars  */  public static int maxmatrix(int [][] ints) {     int max = ints[0][0];      for(int = 0; < ints.length; i++) {         for(int j = 0; j < ints.length){             max = inst[i][j];         }     }     return max; } 

my questions are:

• why assigning variable next 1 in array?
• what conditions , why?

max = inst[i][j];

should max = math.max(max, ints[i][j]);

and...

for(int j = 0; j < ints.length){

should for(int j = 0; j < ints[i].length; j++){

so...

public static int maxmatrix(int [][] ints) {     int max = ints[0][0];      for(int = 0; < ints.length; i++) {         for(int j = 0; j < ints[i].length; j++){             max = math.max(max, ints[i][j]);         }     }     return max; } 

you need math.max. otherwise you're assigning variable next in array

math.max(max, ints[i][j]) equivalent to:

if (max > ints[i][j] {   return ints[i][j];  // or inline in loop: max = ints[i][j]; } else {   return max;         // or inline in loop: max = max; not needed }
