If you want to use the console.log() method in Java, you can create a Console class and add a static log() method. This method has a single print statement to print the message to the console.After creating this class, you can call the log() method by class name. See the example...
在Java中,可以使用Scanner类来读取用户输入,示例代码如下: import java.util.Scanner; public class ReadInput { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); System.out.print("请输入一个整数:"); int num = scanner.nextInt(); System.out.println("您输入的数...
System.out.print("Enter Your Name: ");//PromptBufferedReaderbufferRead=newBufferedReader(newInputStreamReader(System.in));StringinputString=bufferRead.readLine();System.out.println("The name entered: "+inputString); The program output: EnterYourName:LokeshThename entered:Lokesh ...
importjava.util.Scanner;publicclassMain{publicstaticvoidmain(String[]args){Scannerscanner=newScanner(System.in);System.out.print("请输入您的名字:");Stringname=scanner.nextLine();System.out.println("欢迎,"+name+"!");scanner.close();}}
在Test1和Test3中,输入数据前的提示信息需要使用System.out.print();来输出,但是使用基于Console的Test4类,可以在方法参数中直接放入提示信息。 如果需要在控制台中输入密码等敏感信息的话,像在浏览器或者是应用程序中那样显示替代字符,在 JDK 6.0 以前的做法是相当麻烦的(具体的做法可以参考《Java 编程语言中的口令...
