java - java中如何在一行中输入4个不同Int的数字？

Question

问题就这么简单。我想，就像Python一样，找到一种方法，帮助我在一行中输入4个具有不同Int的数字。我的意思是在java中，我想要，输入是:1911输出是:年份:19月份:11

Answer 1

试试这个

try {
    Scanner io = new Scanner(System.in);
    String input = io.next();
    // Note StringIndexOutOfBoundsException
    int year = Integer.parseInt(input.substring(0, 2));
    int month = Integer.parseInt(input.substring(2, 4));
    System.out.println("year: " +  year + "month: " +  month);
} catch (Exception e) {
    e.printStackTrace();
}

测试

1911

输出

year = 19, month = 11

或者

Scanner io = new Scanner(System.in);
String year = io.next(), month = io.next();
System.out.println("year: " +  year + "month: " +  month);

测试

19 11

输出

year = 19, month = 11
