An array of cross-border issues

Error code is as follows:
Scanner in = new Scanner (System.in);
System.out.println (" Please enter the first sequence of length : " ) ;
int m = in.nextInt ();
char [] array = new char [m];
System.out.println (" Please enter the first sequence : " )
for (int i = 0; i array [i] = in.nextLine (). charAt (0);


---------------------------------------------- ----------------------------------
The result:
Enter the length of the first sequence :
5
Exception in thread "main" java.lang.StringIndexOutOfBoundsException: String index out of range: 0

------ Solution ----------------------------- ---------------

  import java.util.*;
  
  public class Test {
  	public static void main(String[] args) {
  		Scanner in=new Scanner(System.in);
  		System.out.println("请输入第一个序列的长度：");
  		int m=in.nextInt();
  		char []array=new char[m];
  	        System.out.println("请输入第一个序列：");
  		in.nextLine(); // 加入这句话 就可以了
  		for(int i=0;i<m;i++)
  			array[i]=in.nextLine().charAt(0);
  	}
  }

------ Solution -------------------------------------- ------
nextInt () Return will be entered after the first nextLine () capture
------ For reference only ------------ ---------------------------
length of the array is fixed and must be initialized
--- --- For reference only ---------------------------------------
in. nextLine () is an empty string , right

------ For reference only ---------------------------------- -----
in.nextLine (). charAt (0) there are problems
------ For reference only ------------------ ---------------------

+1
------ For reference only -------- -------------------------------
