Java中是否有与C的scanf等效的方法? [英] Is there an equivalent method to C's scanf in Java?

问题描述

Java具有格式字符串的概念，与其他语言的格式字符串非常相似.它在JDK方法中使用，例如

Java has the notion of format strings, bearing a strong resemblance to format strings in other languages. It is used in JDK methods like String#format() for output conversion.

我想知道是否有类似于Java中 C的scanf 的输入转换方法?

I was wondering if there an input conversion method akin to C's scanf in Java?

推荐答案

看看

Take a look at this site, it explains two methods for reading from console in java, using Scanner or the classical InputStreamReader from System.in.

以下代码来自引用的网站:

Following code is taken from cited website:

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class ReadConsoleSystem {
  public static void main(String[] args) {

    System.out.println("Enter something here : ");

    try{
        BufferedReader bufferRead = new BufferedReader(new InputStreamReader(System.in));
        String s = bufferRead.readLine();

        System.out.println(s);
    }
    catch(IOException e)
    {
        e.printStackTrace();
    }

  }
}

-

import java.util.Scanner;

public class ReadConsoleScanner {
  public static void main(String[] args) {

      System.out.println("Enter something here : ");

       String sWhatever;

       Scanner scanIn = new Scanner(System.in);
       sWhatever = scanIn.nextLine();

       scanIn.close();            
       System.out.println(sWhatever);
  }
}
