Thread: JAVA - Get array of String from input

Hello,

First element (Zero element) in myString array always is null. Why?
Thanks

import java.util.*;
 
 
class MainClass { 
 
 
	public static void main(String[] args) 
	{ 
		Scanner S = new Scanner (System.in);
		int num = S.nextInt();
 
		String[] myString = new String[num];
 
		for	(int i = 0 ; i < num ; i++)
		{
			myString[i] = S.nextLine();
		}
		String[] MY = null;
		for (int i = 0 ; i < num ; i++)
		{
				MY = myString[i].split(" ");
			for(int j = 0 ; j < MY.length; j++) {
			char[] myChar = MY[j].toCharArray();
			if (myChar[0] >= 97 && myChar[0] <= 122)
			{
				myChar[0]-=32;
			}
			MY[j] = new String(myChar);
			}
			myString[i] = String.join(" ", MY);
		}
		for	(int i = 0 ; i < num ; i++)
		{
			System.out.println(myString[i]);
		}
	}
}
