如何仅在Java中打印字符串的特定部分？

问题描述

我正在编写一个程序，该程序使用字符串的特定部分来写字母。

I am writing a program that writes a letter using specific parts of a string.

到目前为止，这是我所拥有的（我只是一个初学者）

Here is what I have so far (I am only a beginner)

import java.util.Scanner;

public class AutoInsurance {

    public static void main (String[] args)
    {
        Scanner scan=new Scanner (System.in);
        System.out.print("Enter Name:");
        String Name;
        Name=scan.nextLine();
        System.out.print("Enter Street Address:");
        String Address;
        Address=scan.nextLine();
        System.out.print("Enter city, state, and zip code:");
        String Location;
        Location=scan.nextLine();
        System.out.println();
        System.out.println();
        System.out.println("Dear "+Name+",");
        System.out.println(" You have been selected to receive this offer of auto insurance from");
        System.out.println("Allspam Insurance Company! Drivers from "++" saved an average "); // I just want it to print the city here, between ++

        // I will finish coding once I figure this out, but I'm stumped
    }
}

推荐答案

您在这里能做的最好的事情就是拆分您的地址字符串，用逗号隔开，并从结果数组中获取第一个值。

The best you can do here is to split your Adress string, by commas, and grab the first value from the resulting array.

看看，以获取有关在Java中拆分字符串的更多详细信息。

我建议在您的代码中执行以下操作：

I suggest the following in your code:

String[] AddressParts = Address.split(",");
String City = AddressParts[0];
System.out.println("Allspam Insurance Company! Drivers from "+City+" saved an average ");
