java,matrix,integer,max , Finding the maximum integer value contained in a matrix using Java

Question:

Tag: java,matrix,integer,max

I try to code some of this:

``````/*
* @param ints
* @return the max value in the array of chars
*/

public static int maxMatrix(int [][] ints) {
int max = ints[0][0];

for(int i = 0; i < ints.length; i++) {
for(int j = 0; j < ints.length){
max = inst[i][j];
}
}
return max;
}
``````

My question is, can I improve this?

`max = inst[i][j];`

Should be `max = Math.max(max, ints[i][j]);`

and...

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

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

So...

``````public static int maxMatrix(int [][] ints) {
int max = ints[0][0];

for(int i = 0; i < ints.length; i++) {
for(int j = 0; j < ints[i].length; j++){
max = Math.max(max, ints[i][j]);
}
}
return max;
}
``````

You need to do Math.max. Otherwise you're just assigning the variable to the next in the array

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

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