        System.out.println(year+"年"+month+"月"+day+"日);
    }

              int year, month, day;
            System.out.println("请输入 年,月,日：");
            Scanner scanner = new Scanner(System.in);    
            scanner.useDelimiter("[,\r\n]");
            year = scanner.nextInt();
            month = scanner.nextInt();
            day = scanner.nextInt();
             System.out.println(year+"年"+month+"月"+day+"日");

------解决方案--------------------
这个也可以System.in.read();
还有就是用IO流了
BufferedReader br=new BufferedReader(new InputStreamReader(System.in));


------解决方案--------------------
import java.util.Scanner; 
 Scanner input=new Scanner(System.in); 
 System.out.println( "请输入名字： "); 
 String name=input.next();
