Arrays: get the maximum number in each row

[nicky priya]

Hello Everyone, I want to write a program in Java using Arrays.
Write a program to get the maximum number in each row of a 6*4 matrix and also addition of the maximum numbers.
But we should write it without using any inbuilt methods such as collections or any other methods.
for example ....
{ 22  13  9  15  85  56 }
{ 12  14 66 23  35  74}
{ 36  52 25 19 28  45 }
{ 17  26  6  20 35  78 }

What do you have so far, and where are you stuck making progress? If you haven't started yet, what ideas have you had?

If you don't know about Java arrays, start reading at https://docs.oracle.com/javase/tutorial/java/nutsandbolts/arrays.html

I have done as  .. but i want to give all the arrays at same time without using system.in and addition of all maximum numbers.

import java.util.Scanner;

public class MaximumNum {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
         int n , max;
         Scanner scan=new Scanner(System.in);
         System.out.println("Enter the number of elements in the array");
         n=scan.nextInt();
         int a[]= new int[n];
         System.out.println("Enter elements of an array");
         
         for(int i=0; i<n;i++){
        	 a[i]=scan.nextInt();
        	  }
         max=a[0];
         for (int i=0;i<n;i++) {
			if(max<a[i]){
				max=a[i];
			}
		}
         System.out.println("Maximum value :" +max);
	}
}

Well that seems to work. Now you have got it for one array, work out how you would do it for several arrays. You would obviously do something similar several times.
Please space your code a bit; look at these suggestions. Don't use n in a for loop; use myArray.length.
