初学JAVA,怎样获取控制台输入的一行字符串

[ysycrazy]

string str = args[0];

[阿干2]

不用args[]
用System.in....怎么用啊..
我是用Jcreator里写的...

[weixing979]

public class test {

public static void main(String[] args) throws IOException {

BufferedReader stdin = new BufferedReader(new InputStreamReader(System.in));
String str = stdin.readLine();
System.out.println(str);
}
}

JDK5中引入一个新的类，很好用，可以满足你的要求。

java.util
Class Scanner

java.lang.Object
extended by java.util.Scanner

A simple text scanner which can parse primitive types and strings using regular expressions.

A Scanner breaks its input into tokens using a delimiter pattern, which by default matches whitespace. The resulting tokens may then be converted into values of different types using the various next methods.

For example, this code allows a user to read a number from System.in:

Scanner sc = new Scanner(System.in);
int i = sc.nextInt();

简单方便，甩开I/O库的烦琐。

补充一点注意 IOException，我用1.50。每次都不用exception时候总是不能编辑。：）

String s;
JOptionPane.showMessage****
接收再转换

Scaner好像也要的：）

Scanner不错,确实以前的方法太麻烦了.
