JAVA 一問: 點樣可以用cmd 一次過 run program 同開埋果txt file呀!! thx......

public static void main( String[] args )
{
// if you type "java TextFileReader yourText.txt" in the command line
// then "yourText.txt" is stored into the variable fileName as a string
String fileName = args[0];

// do something to open the text file
// where the file name is stored in the variable fileName
//...
}

閣下可以用args陣列便可以在main()內找出輸入的第1個,
(即args[0])
