请问怎么接收键盘输入啊?

[dianhui]

我是一个刚刚学习JAVA的小虾.对于JAVA中的接收键盘输入我到现在还不知道!
去想一定是有很多方法的!希望大哥大姐帮我解解难!
我自己写了一个,可是不对,收到的数据根本就不是我输入的!
代码如下:
try
{
this.year=(int)System.in.read() ;
this.month=(int)System.in.read();
this.datatime=(int)System.in.read();
}
catch (IOException e)
{
System.out.println(e.getMessage());
}

怎么没人帮我呢?

BufferedReader br = new BufferedReader(new InputStreamReader(System.in))
String str = new String();
try{
str = br.readLine();
}catch(IOException e){
}

//str就是你输入的一行了，如果要得到整数 ，可以再转一下int i = Integer.parseInt(str);
//其他类似

楼主得不到想要的数，看看下面的api文档吧，read读的是byte

read
public abstract int read()
throws IOExceptionReads the next byte of data from the input stream. The value byte is returned as an int in the range 0 to 255. If no byte is available because the end of the stream has been reached, the value -1 is returned. This method blocks until input data is available, the end of the stream is detected, or an exception is thrown.
A subclass must provide an implementation of this method.


Returns:
the next byte of data, or -1 if the end of the stream is reached.
Throws:
IOException - if an I/O error occurs.
