Lowest value is always 0 in 2d array

New guy here trying 2D arrays. I have these codes but whenever I run it, the lowest value would always end up with 0 even if I input non-zero digits. Any idea how to fix this?

import javax.swing.JOptionPane;

public class TwoDArrayActivity {
    
    public static void main(String[] args){
        
        // declaration of array
        int a[][] = new int[3][3];  

        int i = 0; // rows
        int j = 0; // columns
        String display = ""; 

        int low = a[i][j];
        
        for(i=0; i < a.length; i++) {   // count the number of rows
            
            for(j = 0; j < 3; j++) {      // count the number of columns
                a[i][j] = Integer.parseInt(JOptionPane.showInputDialog("Enter a Number to Array [" + i + "]" + "[" + j + "]"));
                
                if(a[i][j] < low) 
                    low = a[i][j];
                display = display + a[i][j] + "     ";
            } // end of inner for
            
            display = display + "\n"; //new line 
        } // end of outer for
           
    JOptionPane.showMessageDialog(null,"Values in Array\n" + display + "Lowest value is " + low, "Values in Array", JOptionPane.INFORMATION_MESSAGE);
    } // end of method
} // end of class

>Solution :

Replace :

int low = a[i][j];

with :

int low = Integer.MAX_VALUE;
