PLEASE HELP WITH JAVA

Question

Java max length 2-D array help PLEASE

Please help out over here for java

So I’m doing an assignment where we need to return the number of characters in the table that has the largest number of characters. For example:

Int [] [] table = {{-3, 18, -2053, 13};
{1856, 24601, 7, 92},
{23, 0, 425, -25}};

Return: 5 because -2053 has 5 characters.

I’m just having trouble figuring out how to make the three tables plus for it to read the largest amount of characters. PLEASE HELP

I was able to make a code which will read the largest number.
public class MaxLength {

static int arr[] = { 3, 18, 10,13};

static int largest()
{

int i;

int max = arr[0];

for (i = 1; i < arr.length; i++)
if (arr[i] > max)
max = arr[i];

return max;
}

public static void main(String[] args)
{
System.out.println("Largest in given array is " + largest());
}
}

All I’m asking if someone can help me out with this code. I really really really need help and I will appreciate any help with this code.

Answer 1

This is how it would look.

Answer 2

This one takes additional steps of finding highest positive and negative value. The additional steps is performed in order to reduce number -> string conversion frequency.

Answer 3

Hello You need to check for digits count not for value then you can convert any number to string (check for String.valueOf method) and get the size from that, then apply the comparison. Anyway, just like said by Ipang , i dont understand if you need to return a number in particular or not

Answer 4

- for any number do
- transform the number to string
- get the string length
- compare with current max length
- if its more than current max length, update it to current number length

Answer 5

A slightly cleaner modification of Avinesh code.

int maxCount = 0;
int n = 0;
for(int[] arr : table) {
for(Integer num : arr) {
n = num.toString().length();
if(n > maxCount) {
maxCount = n;
}
}
}

Answer 6

i see
