import java.io.*;
class FileRead
{
public static void main(String args[])
{

try{


var iChars = "*|,\":<>[]{}`\';()@&$#%";
for (var i = 0; i < string.length; i++) {
if (iChars.indexOf(string.charAt(i)) != -1){
System.out.println("Characters found";
}


catch (Exception e){
System.err.println("Error: " + e.getMessage());
}


}
}
}

Please let me know what is wrong with the above code.

It is giving some compilation errors.

I am trying to set an alert once I read the text file which contains special characters.


Help!!!!

I am using this code to read the txt file.


import java.io.*;
class FileRead
{
public static void main(String args[])
{
try{
// Open the file that is the first
// command line parameter
FileInputStream fstream = new FileInputStream("textfile.txt";
// Get the object of DataInputStream
DataInputStream in = new DataInputStream(fstream);
BufferedReader br = new BufferedReader(new InputStreamReader(in));
String strLine;
//Read File Line By Line
while ((strLine = br.readLine()) != null) {
// Print the content on the console
System.out.println (strLine);
}
//Close the input stream
in.close();
}catch (Exception e){//Catch exception if any
System.err.println("Error: " + e.getMessage());
}
}
}
