以下是一个完整的代码示例,演示了如何使用Scanner和while循环来实现循环输入: java import java.util.Scanner; public class LoopInputExample { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); String input; System.out.println("请输入一些文本(输入'exit'退出):"); wh...
import java.util.Scanner; public class Test { public static void main(String[] args) { Scanner s = new Scanner(System.in); int sum = 0; while(s.hasNextInt()) { sum += s.nextInt(); } System.out.println(sum); } } 我们的预期是:程序开始运行后,我们通过键盘在终端键入一行不定数量的...
* a: 导包import java.util.Scanner; * b:创建键盘录入对象 Scanner sc = new Scanner(System.in); * c: 读取键盘录入的一个整数 * int enterNumber = sc.nextInt(); * d: 读取键盘录入的字符串 * String enterString = sc.next(); * B: 案例代码 import java.util.Scanner; public class Demo05...

hello, I am writing a program with java and i have run with while use Scanner to get user input and I pass the input to another Class method. I made a while loop that repeat the method if it return "false" and after the first time that I pass the scanned Input to the method i ...
Why did you use !choice.equals("QUIT") in while loop it will never go inside loop when you enter QUIT. In this case your program will never terminate. Check this I tried to do like this. I don't know it is correct or not according to your requirement. https://code.sololearn.com/...
Looper.loop(); }onCreate后,MSS将会创建一个带消息处理机制的工作线程,那么消息是怎么投递到这个线程中的呢?2. onStartCommand的分析还记得MSR的scan函数吗?如下所示:[-->MediaScannerReceiver.java::scan函数]context.startService( new Intent(context, MediaScannerService.class).putExtras(args));其中...
每个需要“scanner state”的方法都应该首先检查,然后抛出。 单身汉没有州。相反,它的方法将所需的状态作为参数 你的懒汉1没有,比如说,public void menu()。它有public void menu(Scanner s) {}—每次有代码调用它时,它都会传递scanner。 *)这实际上是有道理的,但前提是某些代码引用Lazy1类而没有获得singleto...
However, when I run in debug mode and put a break point in the while loop, the output is this: She She by She by the She by the sea She by the sea shore Similarly, when debugging with test1, the output is (imagine this builds iteratively like above): "The br...
