How to find largest number in multi dimensional array?

Question

Example
Input:{{2,3,5},{6,8,4}}
Output: 8

Answer 1

You could filter through easy element and find the largest number. For instance:
int largestNumber = 0;
for(int i=0;i < input.length;i++){
for(int j=0;j < input[i].length;j++){
if(input[i][j] > largestNumber){
largestNumber = input[i][j];
}
}
}

Answer 2

For the second for loop use arr[i].length
And use max = arr[i][j]; (not two js)

Answer 3

public class MinumArray {

public static void main(String[] args) {
// TODO Auto-generated method stub
int[][] arr= {{2,3,4},{1,0,2}};
int max = arr[0][0];
for(int i=0;i<arr.length;i++) {
for(int j=0;j<arr.length;j++)
if(arr[i][j]>max) {
max=arr[j][j];

}
}
System.out.println(max);
}
}
