Please explain here how this code works and how it does what it was supposed to do (display the rows and columns with the largest values).

import java.util.ArrayList;

import java.util.Random;

import java.util.Scanner;

public class Exercise{

public static void main(String[] args) {

Scanner scnr = new Scanner(System.in);

Random rnd = new Random();

System.out.print("Enter the array size: ");

int n = scnr.nextInt();

int[][]arr = new int[n][n];

int []rowCounts = new int[n];

int []colCounts = new int[n];

ArrayList largestRow = new ArrayList<>();

ArrayList largestCol = new ArrayList<>();

for(int i=0; i

for(int j=0; j

arr[i][j] = rnd.nextInt(2);

for(int i=0; i

for(int j=0; j

System.out.print(arr[i][j]+" ");

}

System.out.println();

}

for(int i=0; i

for(int j=0; j

if(arr[i][j]==1)

rowCounts[i]++;

if(arr[j][i]==1)

colCounts[i]++;

}

}

int rowLargeCount = rowCounts[0];

int colLargeCount = colCounts[0];

for(int i=0; i

if(rowLargeCount

rowLargeCount = rowCounts[i];

if(colLargeCount

colLargeCount = colCounts[i];

}

for(int i=0; i

if(rowLargeCount == rowCounts[i])

largestRow.add(i);

if(colLargeCount == colCounts[i])

largestCol.add(i);

}

System.out.println("The largst row is: "+largestRow.toString());

System.out.println("The largst column is: "+largestCol.toString());

}

}
