从控制台接收一个字符，然后将其打印出来public static void main(String [] args) throws IOException{
System.out.print(“Enter a Char:”)
char i = (char) System.in.read()
System.out.println(“your char is :”+i)
}
}
从键盘输入其它类型数据：
public static void main(String [] args) {
Scanner sc = new Scanner(System.in)
System.out.println(“请输入你的姓名：”)
String name = sc.nextLine() //字符串
System.out.println(“请输入你的年龄：”)
int age = sc.nextInt() //整数
System.out.println(“请输入你的工资：”)
float salary = sc.nextFloat() //浮点数
System.out.println(“你的信息如下：”)
System.out.println(“姓名：”+name+“\n”+“年龄：”+age+“\n”+“工资：”+salary)
}
