Code throwing error that m can not be found

Question

import java.util.Scanner;
public class Program
{
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
String myName = sc.nextLine();
int agents = Integer.parseInt(sc.nextLine());
String [] m= new String [4];
String a = m[0];
String b =m[1];
String c=m[2];
String d =m[3];
int q;
int w;
int e;
int r;

char [] z = {'a','A','b','B','c','C','d','D','e','E','f','F','g','G','h','H','i','I','j','J','k','K','l','L','m','M','n','N','o','O','p','P','q','Q','r','R','s','S','t','T','u','v','w','x','y','z','U','V','W','X','Y','Z'};
for(int j=0;j<=3;++j){
m[i]=sc.nextLine();
}
for(int i=0;i<=51;++i){
if(myName.charAt(0)==z[i]){
q = i;

}
if(a.charAt(0)==z[i]){
w = i;

}
if(b.charAt(0)==z[i]){
e =i;
}
if(c.charAt(0)==z[i]){
r = i;
}
}

int [] v = {q,w,e,r};
System.out.print(v[0]);

}
}

Answer 1

Idk if that fixes your problem but in the first for loop you used j as an iteration variable but used i in the body.

Answer 2

Did you catch it?
When you share a code, tell us what you are trying to do, what is the input like etc. This would help the community to help you solve your problem soon.

Answer 3

It's showing NosuchElement exception
