How to use Enter to continue inputting text in Java

Direct answer:
In Java, you can use nextLine() Method reads a string with spaces from the keyboard until the Enter key is pressed.

Detailed expansion:

nextLine() method belongs to the java.util.Scanner class, which is used to read from Read data from the input stream. When you use this method to read a string, it reads a sequence of characters from the keyboard until it encounters the Enter key (\n).

Code example:

import java.util.Scanner;

public class InputExample {

    public static void main(String[] args) {
        // 创建 Scanner 对象
        Scanner scanner = new Scanner(System.in);

        // 使用 nextLine() 方法读取带空格的字符串，直到按下回车键
        System.out.println("请输入您的姓名：");
        String name = scanner.nextLine();

        // 使用 nextLine() 方法读取带空格的字符串，直到按下回车键
        System.out.println("请输入您的地址：");
        String address = scanner.nextLine();

        // 输出输入的数据
        System.out.println("您的姓名：" + name);
        System.out.println("您的地址：" + address);
    }
}

In the above example:

• Scanner scanner = new Scanner(System.in); Creates a Scanner object that will read data from standard input (usually the keyboard).
• String name = scanner.nextLine(); Use the nextLine() method to read a string with spaces from the keyboard and store it in name variable.
• String address = scanner.nextLine(); Use the nextLine() method to read another string with spaces from the keyboard and store it in address variable.
• Finally, the System.out.println() statement outputs the input data.
