以下示例显示java.io.Console.reader()方法的用法。
package com.jc2182;
import java.io.Console;
import java.util.Scanner;
public class ConsoleDemo {
public static void main(String[] args) {
Console cnsl = null;
Scanner scan = null;
try {
// creates a console object
cnsl = System.console();
// if console is not null
if (cnsl != null) {
// prints
System.out.print("Enter name : ");
// create new scanner object
scan = new Scanner(cnsl.reader());
// read till the end of data
while (scan.hasNext()) {
// read next
String str = scan.next();
// print
System.out.println(str);
}
}
} catch(Exception ex) {
// if any error occurs
ex.printStackTrace();
}
}
}
让我们编译并运行以上程序,这将产生以下结果-
