嘿,我需要代码来替换行尾的txt文件中所有连词的出现。我有一个保存在txt文件中的连词列表。我希望输入的文件和连接文件都以数组形式存储。然后使用for循环我想比较两个数组。但这会产生很多错误。那里有一个更好的方法来做同样的事情? 这是我尝试做的,但它在for循环中显示错误
import java.util.List;
import java.util.Scanner;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.swing.JFileChooser;
public class Toarray
{
private static Object arrays;
public static void main(String args[]) throws FileNotFoundException
{
String filename,path;
System.out.println("select the input file");
JFileChooser chooser = new JFileChooser();
chooser.showOpenDialog(null);
File file1 = chooser.getSelectedFile();
chooser.showOpenDialog(null);
filename = file1.getName();
path= file1.getPath();
Scanner sc;
sc = new Scanner(new File(filename));
List<String> lines = new ArrayList<String>();
while (sc.hasNextLine()) {
lines.add(sc.nextLine());
}
String[] inp = lines.toArray(new String[0]);
for (int index=0;index<=20;index++ ){
System.out.println(inp[index]);}
String remove;
remove="/Machintosh HD/Users/vaishnavi/Desktop/temp.txt";
Scanner sc1;
sc1 = new Scanner(new File(remove));
List<String> con;
con = new ArrayList<String>();
while (sc1.hasNextLine()) {
lines.add(sc1.nextLine());
}
String[] conj = con.toArray(new String[0]);
}
StriString oldtext;
for(int i=0;i<=55;i++)
{
for(int j=0;j<=75;j++)
{
if( inp[i].equals(conj[j]))
{
String newtext = oldtext.replaceAll(inp[i], ".");
FileWriter writer = null;
try {
writer = new FileWriter(path);
} catch (IOException ex) {
Logger.getLogger(Toarray.class.getName()).log(Level.SEVERE, null, ex);
}
try {
writer.write(newtext);
} catch (IOException ex) {
Logger.getLogger(Toarray.class.getName()).log(Level.SEVERE, null, ex);
}
}
}
}
}
请帮助:)

要检查数组是否包含某些内容,请尝试以下操作:
if(Arrays.asList(inp).contains("something")){
//Do something
}
