import java.util.Scanner; public class Main { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); System.out.print("请输入一个字符串: "); String str = scanner.nextLine(); System.out.print("请输入一个整数: "); int num = scanner.nextInt(); System.out...
java import java.util.Scanner; 接下来,我们就可以创建Scanner对象了。通常情况下,我们将Scanner与System.in关联起来,以便从键盘读取用户输入的数据。具体做法如下: java Scanner scanner = new Scanner(System.in); 二、基本的读取方法 1. next()方法 next()方法用于读取用户输入的下一个完整单词,它会自动过滤掉...
因此,通常在使用 nextInt() 时,会结合 try-catch 块来处理可能的异常。 Scanner.nextInt() 的基本用法 java import java.util.Scanner; public class ScannerNextIntExample { public static void main(String[wap.xadzgs.com] args) { Scanner scanner = new Scanner(System.in); System.out.print("请输入...
AI代码解释 importjava.util.Scanner;publicclassdd{publicstaticvoidmain(String[]args){Scanner scan=newScanner(System.in);// 从键盘接收数据// next方式接收字符串System.out.println("nextLine方式接收:");// 判断是否还有输入if(scan.hasNext()){String str1=scan.nextLine();System.out.println("输入的数...
在以下示例中,我们使用Scanner类和in.hasNextInt()方法创建了一个无限循环,直到用户输入一个整数为止: 代码语言:java 复制 importjava.util.Scanner;publicclassMain{publicstaticvoidmain(String[]args){Scannerin=newScanner(System.in);System.out.println("请输入一个整数:");while(!in.hasNextInt()){Sy...

下面是一个简单的示例代码：java public class TestScanner { public static void main(String[] args) { Scanner s = new Scanner(System.in);System.out.println("请输入字符串：");while (true) { String line = s.nextLine();if (line.equals("exit")) { break;} System.out.println("...

The findInLine(java.lang.String), findWithinHorizon(java.lang.String, int), and skip(java.util.regex.Pattern) methods operate independently of the delimiter pattern. These methods will attempt to match the specified pattern with no regard to delimiters in the input and thus can be used in spe...
