Here's what I have so far:
这是我到目前为止所拥有的：
import java.util.Scanner;
public class exercise_4{
public static void main(String [] args){
Scanner scan = new Scanner(System.in);
int a;
a = 0;
System.out.println("Please enter your words");
String word = scan.nextLine();
System.out.println(word.charAt(a));
}
}

You can try something like this:-

String word = scan.nextLine();
for(char c : word.toCharArray())
System.out.println(c);
}

Split word into characters
将单词拆分为字符
String[] parts = string.split("");
print characters, one per line
打印字符，每行一个
for(String char : parts){
System.out.println( char );
}

for(int i=0;i<word.length();i++)
System.out.println(word.charAt(i));
