Java multi dimensional array

Question

I want to search a multi-dimensional array and print the numbers greater than 7 with their locations.

This code compiles and runs without any errors, but doesn't provide any output.

Please help me to solve this problem.

class Sarr{
 public static void main(String args[]){ 
 int[][] numArray = {{1,2,5,6,4,0},{6,0,1,2},{1,7,3,4},{3,5,6,8,5}}; 
 arr(numArray);
 }
 private static void arr(int [][] array){
 int val = 7;
 for (int r = 0; r < array.length; r++) {
 for (int c = 0; c < array[r].length; c++) {
 if (array[r][c] > val){
 System.out.println("Value found was " + val + "["+r+"]"+"["+c+"]");
 }
 } 
 }
 } 
}

• Goran Jovic: Ok, so what does it output now that you added an 8?
• Narayan: you edit the test array, which you pass as a reference, on my machine it o/p as Value found was 7[3][3]
• shavinda: tnx all... i totally forgot to add a value greater than 7, to my array. i edit it and compiled it. now it works.

Answer 1

Your test array does not have any element which is> 7 ...

Answer 2

The problem is that there is no number greater than 7 in your array. If you want it to print 7's you will need to change your if statement to

if(array[r][c]>=val) {
 //Print
}

Answer 3

It's because you're looking for strictly array[r][c] > 7 none of the values in your array are greater than 7.
