想要读取一个字符型数据怎么写输入语句

[蹦极的考拉]

char b;
Scanner a=new Scanner(System.in)
a=input.请问这里填写什么？


或者请高手告诉我怎么写这个语句吧

char c=0;
Scanner scanner = new Scanner (System.in);
while(scanner.hasNext()){
char[] cArr = scanner.next().toCharArray();
c = char[0];
if(c=='q'){
System.exit(0);/退出
}
System.out.println("读取字符:"+c);
}
