java - 如何用并行数组替换单词

Question

您好，我是这个论坛的新手。我是 Java 的新手。我正在尝试将美国单词转换为英国单词，这样当我输入包含任何美国单词的句子时，输出将是该句子但替换为英国单词。这是我的尝试:

import javax.swing.JOptionPane;
public class PArraystest
{
    public static void main(String [] arg)
    {
    String[] wordUSA = {"Cell", "Elevator", "Fries", "Gasoline", "Faucet"};
    String[] wordUK = {"Mobile", "Lift", "Chips", "Petrol", "Tap"};
        String changeUK = "";
        String sent;
        sent = JOptionPane.showInputDialog("What name do you want to search for?");
        for (int i = 0; i < wordUSA.length; i++)
        { 
            if (sent.contains(wordUSA[i]))
        {

                sent.replace((wordUK)[i],(wordUSA)[i]);
            //break;
        }
        }
            //if (changeUK.equals(""))
            //System.out.println(" was not found.");
            //else
            System.out.println(sent);   
            }
        }

两件事:

1. 您需要将replace返回的字符串再次赋值给sent，否则sent将保持不变`。

2. replace 方法是public String replace(char oldChar, char newChar)，所以oldChar US word应该放在第一位，后跟英国单词。

这是正确的行:sent = sent.replace(wordUSA[i],wordUK[i]);
