我要的是接收一个字符并循环5次，为什么执行后出现

public static void main(String[] args) {
for (int a = 0; a < 5;a++ ) {
System.out.print("Enter a character please:");
Scanner cin=new Scanner(System.in);
String name=cin.nextLine();
System.out.println("You've entered character:" + name);}
}

中间空的那些应该是每一行结尾的\r和\n
字符和字符串其实没什么区别 接收字符串就行
实在要用可以开个byte数组，用read(byte[])

建议用
ch=(char)scanner.nextInt()；
